AWC/ICC Publish
High Wind Guides
|
AF&PA's
American Wood Council (AWC) and the International
Code Council (ICC) are pleased to announce the release
of AF&PA's newly-developed Guides to Wood Construction
in High Wind Areas.
With a tremendous need in the hurricane-prone Southeast for simple
design tools, AWC has developed a new series of easy-to-use Guides
for builders who are constructing one- and two-family dwellings
in high-wind areas of the country. This new series of publications
is co-branded with ICC and targeted at builders.
"
These customized guides will be highly effective
in improving construction and safety of homes
in hurricane-prone regions. When used in conjunction
with the ICC's hurricane resistant construction
requirements, they provide simplified solutions, |

increased
consistency, and improved building code compliance" said
Wally Bailey, President of ICC and Director of Development & Construction
with the City
of Fort Smith, Arkansas. Individually-published Guides
address design requirements in 90, 100, 110, 120, and 130
mph wind zones, respectively. The Guides are simplified
versions of AF&PA's building-code-recognized Wood Frame
Construction Manual (WFCM) for One- and Two-Family Dwellings
2001 Edition. Prescriptive solutions presented in the Guides
are compatible with the WFCM 2001 and in compliance with
the ICC family of building codes. For example, use of any
of the Guides will result in design solutions that prescriptively
meet the requirements of the International Residential
Code.
These Guides were developed with input from, and in cooperation with, the
National Association of Home Builders, FEMA/URS, ICC, and the Institute
for Business and Home Safety.

Recently,
Dr. Jeffrey Stone, Southwest Senior Regional Manager
for AF&PA, presented four programs on the guides to
different areas of Louisiana. Henry H. Fry, the acting
State Fire Marshal for Louisiana, wrote: "The presentation
I personally attended was most informative, and provided
significant insight about Louisiana's new building
code. Your contribution has made the difficult task
of implementing the new code a lot easier, and is greatly
appreciated. Thank you for taking the time to present
your valuable expertise in such clear and understandable
terminology. Those of us who participated gained a
great deal from this experience." |

Cooperative Agreement Concludes |
AF&PA's
American Wood Council held their final project review
meeting with representatives of the United States Fire
Administration, Department of Homeland Security at
the National Fire Academy in Emittsburg, MD. Begun
in 2003, the cooperative agreement was undertaken to
raise awareness within the fire service of wood products
used in building construction. After meeting with fire
service instructors from around the country, a series
of fire service "Awareness Guides" were developed and
are available on the www.woodaware.info website.
The site will be maintained by AWC and is dedicated
to providing current information on fire performance
of traditional and engineered wood products.
|
One
of eight fire service "Awareness Guides" developed
through a cooperative agreement between AF&PA's American
Wood Council and the U.S. Fire Administration, Department
of Homeland Security. |
|
Also,
as part of the project, eight
wood display cases were built
by Building Construction Technology students
at C.S. Monroe Technical Center in Leesburg, VA. Product
samples were furnished by Shelter Systems, Open Joist 2000,
and the Weyerhaeuser Company. The cases will be distributed
to the state fire academies that participated in the cooperative
agreement.
Bill Troup, Department of Homeland Security, and Dr. Kuma Sumathipala,
American Wood Council, discuss the wood product display
case that was presented to the National Fire Academy by
AF&PA.

| In
Memoriam: Roderick Bruce Buchan |
 |
Retired
National Forest Products Association (NFPA) assistant
vice president, Roderick Bruce Buchan, died on November
28. Buchan worked for NFPA, the predecessor organization
to AF&PA, for 28 years in a variety of capacities,
including as regional engineer in the Los Angeles district
office and later at NFPA headquarters as head of the
field staff.
Rod began his professional building code career as a building official
for Pasadena, CA. He was a licensed professional civil engineer and
a licensed professional fire protection engineer, having graduated
from the School of Engineering at the University of Southern California. |
In World
War II, he served as a corporal in the Marine Corps, engaged
in the Pacific Theater of Operations.
Rod's outstanding contributions to the wood industry included his success
in influencing International Conference of Building Officials (ICBO) activities
while he was the NFPA representative in that region. His position on ICBO
and Council of American Building Officials (CABO) advisory committees provided
a valuable means for industry input into those organizations. His participation
on the National Institute of Building Sciences' Consultative Council helped
that organization maintain an important watchdog role over development
of codes and standards that might adversely affect the wood industry. And
his efforts were seen as being influential in convincing the city of Washington,
DC to adopt a national model building code. In 1978, Rod was honored by
ICBO with the John Fies Award, in recognition of his substantial contribution
to ICBO as a member of industry. He retired from NFPA in 1989.
Surviving are his wife, Janice L. Buchan; his son, James, daughter Susan,
and two grandchildren. In lieu of flowers, the family requests that memorial
donations be made to the American Heart Association, Memorial Processing
Center, P.O. Box 5216, Glen Allen, VA 23058, or the American Diabetes Association,
Maryland Affiliate, 800 Wyman Park Drive, Suite 110, Baltimore, MD 21211.

| WTCA
Updates Load Guide |
WTCA
recently introduced The Load Guide (TLG), v1.02 Beta, a Guide
to Good Practice for Specifying & Applying Loads to Structural
Building Components. This update is a significant revision
from past versions. In addition to a large number of general
improvements, TLG v1.02 adds code requirements from the International
Building Code (IBC) 2006 and International Residential Code
(IRC) 2006, along with loading requirements from ASCE 7-05,
Minimum Design Loads for Buildings and Other Structures.
|
  |
"The
Load Guide is a great tool to help explain to customers
or technical staff that trusses require more information
than pitch, span and fascia details to design correctly," said
Bob Dayhoff, Chair of WTCA's Engineering & Technology
Committee and Director of Technical Operations at Shelter
Systems Limited in Westminster, MD. |
|
Focusing on
floor, roof and dead loads, TLG is a series of Microsoft® Excel
spreadsheets, free to the public, designed to help users
understand, define
and specify all the loads that should be applied to the
design of structural building components. In addition to
allowing users to calculate loads specific to a given building
project, the spreadsheet includes reference materials and
commentary so that determining the applied loads is easier
to understand. The guide also provides three valuable load
calculation worksheets that define all the loading criteria
that have been agreed upon for loading a specific building
component-one each for roof loads, floor loads, or a summary
of dead loads. These sheets can be printed out or saved
in an electronic portable document format (pdf) and added
to the construction project documentation.
TLG provides the code and/or standards-based requirements for determining
design loads specifically for metal plate connected wood trusses and related
structural building components. The document offers industry consensus
positions on the application of code requirements for loading structural
building components, with particular emphasis given to those code provisions
that have been found to suffer from inconsistent interpretation within
the construction industry. This resource provides industry consensus interpretations
and commentary using examples that are industry specific, along with practical
interpretations of some of the more unique structural building component
loading situations. TLG is in no way intended to supersede an architect's
or engineer's judgment and design specification for the loads that should
be applied to a specific building; rather, it serves as a guide and the
basis for coming to an agreement on the loads that should be applied.
A cooperative development between the Truss Plate Institute (TPI) and WTCA,
TLG is available at www.sbcindustry.com/loads.php.
Please be sure to save the document locally for reviewing.

Report Released |
The
National Council for Air and Stream Improvement, Inc. (NCASI)
just released a report titled Energy and Greenhouse Gas Impacts
of Substituting Wood Products for Non-Wood Alternatives in
Residential Construction in the United States. In this study,
NCASI received USDA Forest Service funding from the Resources
Planning Act (RPA) Assessment Program to estimate the effects
of using wood-based building materials on national energy
use and greenhouse gas emissions. Data developed by the Consortium
for Research on Renewable Industrial Materials (CORRIM) were
used in an analytical framework that allowed carbon in forests
and forest products to be tracked over large areas and long
time frames. In addition, NCASI developed a module to follow
the fate of carbon in discarded building materials. To ensure
that short-term and transient effects did not bias the findings,
a time horizon of 100 years was used.
The results indicate that houses with wood-based wall systems required
approximately 15 to 16% less total energy for non-heating/cooling purposes
than thermally-comparable houses employing alternative steel- or concrete-based
building systems. The results for non-renewable energy consumption were
essentially the same as those for total energy, reflecting the fact that
most of the displaced energy was in fossil fuels.
Net greenhouse gas emissions associated with wood-based houses were 20
to 50% lower than those associated with thermally-comparable houses employing
steel- or concrete-based building systems. Only a small fraction of the
building materials need to be changed to accomplish these improvements.
In an Atlanta-based example, the additional wood used in the wood-based
house represented only 2.3% of the mass of the house, while in the Minneapolis-based
example, the additional wood used in the wood-based house represented 7.7%
of the mass.
On an annual basis, assuming 1.5 million housing starts a year, the difference
between wood and non-wood building systems is about 9.6 million tons of
CO2 equivalents per year, and the corresponding energy benefit associated
with wood-based building materials is approximately 132 million GJ per
year. These figures represent approximately 22% of the embodied energy
and 27% of the embodied green house gas emissions in the residential sector
of the economy.
The estimates developed in this study were found to be very sensitive to
assumptions about carbon accumulation in forests and about the fate of
carbon in forests no longer needed for production of wood building materials.
Future studies would benefit from a more refined analysis of these issues
as well as an analysis of the benefits of producing energy from forest
biomass under a variety of scenarios. In addition, the estimates would
be improved if data were available for houses representative of regions
not included in the CORRIM Phase I work.

| AWC
Launches CAD Details |
Responding
to user requests, AWC has launched a new section on its website
which allows designers to download electronic computer-aided
design (CAD) details found in many of AWC’s popular
standards and publications. The most requested details have
been figures from AF&PA’s Wood Frame Construction
Manual (WFCM) for One- and Two-Family Dwellings, 2001 Edition.
The building code-referenced WFCM has gained widespread
acceptance among the building design community, especially
in high wind and high seismic regions. As a result, users have
begun incorporating many of the design and construction figures
from the WFCM into their documents and drawings. Having
these figures in various electronic formats allows users the
flexibility to import and customize them for their specific
needs.
On the webpage, electronic file formats provided are GIF, DXF,
DWF, and DWG. Access to the CAD files is available via an icon
in the upper right side of the AWC homepage at www.awc.org,
from the menu bar on any page, or directly at: http://www.awc.org/CAD/index.html.
Designers visiting the AWC website have commented on the vast
array of resources available. One California structural engineer
wrote, “AWC…has done more than most professional
sites I have been on to help improve the quality of construction
and understanding of the various methods they support.”
Work is underway to incorporate more drawings onto the website,
including those from Details for Conventional
Wood Frame Construction - WCD No. 1 and the various fire
assemblies from DCA No. 3 - Fire Rated Wood Floor and Wall
Assemblies.

Announces New President & CEO |
 |
Michael
E. Case, President and CEO of The Westervelt Company
and Chairman of the Board for the American Forest & Paper
Association (AF&PA), announced on July 14 that
Juanita D. Duggan has been selected to be AF&PA’s
new President and CEO. Ms. Duggan will assume her duties
on October 25, 2006, replacing W. Henson Moore, who
last October announced his intention to retire in 2006.
“We are very excited to have Juanita lead our industry’s public policy

Elected Vice-Chair of ICC-IAC |
 |
Kenneth
E. Bland, AF&PA Senior Director of Codes and Standards,
was elected to serve a two-year term as vice-chair
of the International Code Council's (ICC) Industry
Advisory Committee (IAC). The IAC is comprised of 94
organizations representing professional, labor, trade,
voluntary standards, public interest organizations,
and public agencies. The IAC provides a forum for industry
to develop and make recommendations for consideration
by the ICC Board of Directors.
Additionally, the IAC voted to recommend that the ICC
Board not |
develop
technology to allow for building officials to vote on code
change proposals from sites remote from the actual hearings.
The proposal was developed to provide an opportunity for greater
building official participation in the code development process.
Although not unanimous in its negative recommendation, many
IAC members were fearful that proper safeguards could not be
put in place to ensure that a person voting from a remote location
would have the benefit of the meeting testimony.
At the meeting, ICC staff also reported on a broad range of activities occurring
within ICC, including standards development and hearings scheduled for the upcoming
code development forum in Orlando, FL. Of primary interest was the announcement
of an agreement in principle to develop a single plumbing code with the International
Association of Plumbing and Mechanical Officials (IAPMO). The IAPMO Uniform
Plumbing Code continues to compete with ICC’s International Plumbing
Code (IPC), primarily in the western United States. While met with considerable
reservation by many IAC members, the relationship is seen by ICC as removal of
the final barrier to being the undisputed leader in code promulgation and adoption
in the United States.

of Australia. |
|
| As
co-sponsor, AWC presented the 2006 Wood Engineering Achievement
Award at the 60th International Convention of the Forest
Products Society (FPS) to the Manufacturing and Infrastructure
Technology division of the Commonwealth Scientific and Industrial
Research Organization (CSIRO) and Forest and Wood Products
Research and Development Corporation of Australia (FWPRDC).
The CSIRO/FWPRDC team has developed engineering models and
software called TimberLife – Service Life Prediction
of Wood Construction, which are intended to provide
standardized methods for assessing durability issues in buildings.
Dr. Gregory C. Foliente, team leader for this project at
CSIRO, accepted the award on behalf of his team.
One award nomination stated, “…these first generation
serviceability/durability models for wood construction exposed
to environments conducive to above-ground decay, ground-contact
decay, termite attack, marine-borer attack, or corrosion
will be viewed as a milestone for wood engineering in the
not-so-distant future. Engineers in every structural material
around the world are now demanding that serviceability and
durability be given equal consideration as structural integrity.
The vision and resourcefulness of this CSIRO/FWPRDC team
over this 10-year research and development project has led
to the first major step within the wood engineering community
to specifically address this demand. As such, this project
exemplifies the true meaning of engineering innovation that
is the theme of this year’s award.”

| AWC Launches
eQuiz System |
|
Culminating
two years of development, the American Wood Council
(AWC) is pleased to announce the launch of its online
eQuiz system. A link on the AWC homepage directs
users to the eCourses webpage at http://www.awc.org/
HelpOutreach/eCourses/index.html. When used with
AWC’s online “eCourses,” the eQuiz
system provides users with the additional feature of
accredited continuing education credit. Many users
|
|
have
expressed appreciation for the convenience of earning valuable continuing
education credits in the comfort of their own surroundings
on their own schedule.
Registration for eQuizzes is straightforward and is required
for participation. The system is designed so that eCourse
materials and eQuizzes can be displayed in separate windows,
much like an open-book test, as permitted by the accreditors.
Taking the eCourses and tests is free of charge and provides
an informative and integrated learning experience. For each
eCourse, users are queried on the subject matter with feedback
immediately provided for all answers.
The eQuiz system boasts some novel features, including a
variety of question formats such as multiple choice, true/false,
and matching. Every eQuiz is entirely unique for each user,
and among users, with questions and their order of presentation
posed differently with each test. The bottom line is that
no two eQuizzes are ever alike and every test experience
is unique, preserving the integrity of the system. Once a
learner has successfully completed an eQuiz, an option is
provided to purchase and print a continuing education certificate
if desired. Pricing varies among courses based on their length
(1.0 to 4.0 CEU’s), but typically cost about $25 for
2.5 CEU’s.
Continuing education certificates are honored by any agency
accepting AIA (American Institute of Architects), IACET (International
Association for Continuing Education and Training), and the
AIBD (American Institute for Building Design) protocols for
online training. As required, AWC reports awarded continuing
education credits to registering agencies at the beginning
of each month for the previous month’s online activity.
For more information about the eQuiz system, contact Dr.
Robert Taylor at 202/463-2771 or robert_taylor@afandpa.org.

AWC
has developed a new series of easy-to-understand guides
for designing wood-frame homes in high wind areas such
as the Southeast. See a sample page below. |
dwellings
in high-wind areas of the country. Under the agreement,
this new series of publications will be co-branded with ICC
and targeted at builders.
Separate documents will address design requirements in 100,
110, 120, 130, 140, and 150 mph wind zones. These Guides are
simplified versions of AF&PA's building-code-recognized Wood
Frame Construction Manual (WFCM) for One- and Two-Family Dwellings
2001 Edition. Prescriptive solutions presented in the
Guides are compatible with the WFCM 2001 and are in
compliance with building codes. Use of the Guides will result
in design solutions that prescriptively meet the requirements
of the International Residential Code.
These Guides are being developed with input from, and in cooperation
with, the National Association of Home Builders, FEMA/URS,
ICC, and the Institute for Business and Home Safety.

| New
NDS Commentary Available |
A
new Commentary on the 2005 National Design Specification® (NDS)
for Wood Construction was recently posted on AWC’s
website at http://www.awc.org.
The new Commentary is intended to respond to user needs for
background information and interpretive discussion of the
provisions of the building-code-referenced 2005 NDS.
For ease of use, the Commentary follows the same subject matter
organization as the NDS. Discussion of a particular NDS provision
is identified in the Commentary with the same section
or subsection number for that provision in the NDS.
Commentary on each provision consists of background information,
interpretation, or example. References containing more detailed
information on the subject are included. Interpretive discussion
of how a provision should be applied is also provided where
the specific intent of a requirement may be ambiguous.
Adopted in all model building codes in the United States, the NDS is
used to design wood structures worldwide. Release of the 2005
Wood Design Package, which will include the NDS, NDS
Commentary, and other design documents, is expected this
summer.
The first Commentary
on the 1991 National Design Specification for Wood Construction,
prepared by renowned wood expert Dr. Edward King, was published
by AF&PA in 1993. It contains extensive background information
concerning provisions of the NDS, complete with historical
development, example problems, and tables comparing the 1991
design provisions with earlier editions of the standard. An
addendum to the Commentary was later published corresponding
to the 1997 NDS. Both the 1991 and 1997 NDS Commentaries are
still available on the AWC website.
For more information about the NDS Commentary, contact

Blog Launched |
Podcasting,
Blogs, and Wikis—Can New Technology
Lead to More Efficiency?
(Reprinted from
the June 2006 issue of Structure Magazine, written
by AWC’s John “Buddy” Showalter, P.E.)
|
I
certainly don’t claim to be a technology guru. However,
part of my job involves trying to determine the most effective
ways to communicate technical information to engineers, architects,
and building officials. I also constantly try to learn new
ways to be more efficient and effective in my own work environment.
So, can technology’s new communications tools lead
to more efficiency, or are podcasting, blogs, and wikis just
another passing technology fad? And, what do any of these
have to do with structural engineering? Here are some possible
ideas to consider.
Podcasting
Is
podcasting the future for continuing education? Did you know
that 60% of all vehicles manufactured today are iPod compatible?
If continuing education material is developed in 20-30 minute
podcasts, would engineers take advantage and listen to CEU
material on their commute?
|
Definitions*
podcast
A
non-music audio broadcast that has been converted
to an MP3 file or other audio file format for playback
on a digital music player. Developed by former
MTV VJ and Internet businessman Adam Curry in 2004,
the term was coined from Apple's iPod. Using the
RSS 2.0 syndication format, podcasts are made available
to subscribers just like news feeds. The client
program that captures the audio feeds and synchronizes
them with the music player is a “podcatcher.”
blog
(WeBLOG)
A Web site that contains dated entries in reverse
chronological order (most recent first) about a
particular topic. Functioning as an online newsletter,
blogs can be written by one person or a group of
contributors. Entries can contain commentary and
links to other Web sites, and images as well as
a search facility may also be included. A blog
with video clip entries instead of text is called
a “video Weblog” or “vlog.”
wiki
A
Web site that can be quickly edited by its visitors
with simple formatting rules. A Wiki was first
developed by Ward Cunningham in the mid-1990s to
provide collaborative discussions. “Wiki
wiki” means “quick” in Hawaiian.

How
about podcasts of technical articles, like those in Structure magazine?
Imagine the opportunity to “catch up on your
reading” on your commute home, listening to articles
recorded in MP3 format? There might be a commercial
or two involved to help defray the cost to the publisher,
but it certainly could be an efficient way of keeping
up with some of those stacks on our desks that we’d
like to “get to someday.”
Blogs
Blogging,
using or participating in a blog, could be used by a
company to obtain customer feedback. What if you were
able to get this feedback instantaneously, in a format
your customers were comfortable providing? Whether you
admit it or not, your customers are talking about you.
Some may not tell you directly, but they are talking
to fellow customers or talking with their wallet (going
elsewhere). And while I am sure that most customers are
saying good things about you, a few may be criticizing
aspects that you need to know about. Instead of all that
going on behind your back, why not use the power of the
Web to put it all in a format that benefits you—both
the good and the bad? A blog could also be used for project
management. It could be set up as an Intranet accessible
only to certain users. Instead of following discussions
in a folder in your e-mail system, a blog allows the
thread to be organized and searchable using a Web browser.
Just to demonstrate how easy it is to set up a blog,
I created one myself. If you’d like to check it
out, visit:
|
|
http://www.awc.org/wood-design//index.html where
I’ve begun to blog some of the frequently asked questions
(FAQs) to our helpdesk. Perhaps you have your own FAQs
from architects and builders. A blog might be a way for
your company to provide a forum for your customers to ask
questions and receive feedback. For those of you worried
about “liability,” comments can be actively
moderated to keep offensive or questionable content from
being posted.
Wikis
Have you ever worked
on a document with a
group of people and had several drafts floating around? You’re
not always sure which one is current and if someone forgets
to turn on “track changes,” you’re not even
sure what changes were made. Enter the “wiki,” a
type of web site that allows users to add and edit content
in real time.
Similar
to Lotus Notes, a wiki is far less expensive, while offering
80% of the functionality of a full-blown collaboration tool.
So far, only a few big time companies such as Best Buy®,
Yahoo!®, and Walt Disney® have
adopted this technology, but predictions are that by 2009,
fifty percent of companies will have adopted wikis as a collaboration
tool.
Probably the most familiar wiki is
Wikipedia (http://en.wikipedia.org/wiki).
Their welcome page touts, “Welcome to Wikipedia,
the free encyclopedia that anyone
can edit.” The beauty of this technology is the ability
to “roll back” pages to previous edits if erroneous
or poorly written content is added.
Applications for your organization
might be development of specifications and other documents
requiring collaboration. Similar to a blog, it could be set
up as an Intranet, with password protection.
Keeping Up
Are
you keeping up with technological advances? It seems to be
advancing at a blazing pace. Consider these statistics:
| |
-
Processing power doubles every 18 months |
| |
-
Storage capacity doubles every 12 months |
| |
-
Bandwidth throughput doubles every 9 months |
Conclusion
So, can new technology
lead to more efficiency, or are podcasting, blogs, and wikis
just another passing technology fad? The only way I know how
to find out is to try it. We’ve all done it—from
calculator to computer, from typewriter to word processor,
from snail mail to e-mail and then instant messaging, from
desk to cell phones, from desktops to laptops…what’s
next? Ask your kids. They’ll “text message” the
answer to you. |
| AF&PA Presents
Wood Design Seminar in Idaho |
Furthering
its mission of providing quality education to designers,
AWC staff was invited to present an all-day program
to the Structural Engineers Association of Idaho
(SEAI) on building code requirements for various
types of building materials, design methodologies,
the 2005 NDS®, fire-rated assemblies,
and design of wood connections. The group’s
newsletter article which followed the event
|
|
|
noted:
“SEAI officers continually strive to provide highly relevant information
to our membership and the Idaho engineering community through our meetings and
seminars. Judging by the seminar turnout last month, it’s apparent that
wood remains an important building material in Idaho… With that in mind,
SEAI was proud to have sponsored the Wood Design Seminar last month.
“SEAI would like to thank Robert Taylor and James Bowman for their presentations,
and all those that attended the seminar.”

| Illinois Task
Force Recommends Adoption of Statewide Building Code |
The
Illinois Task Force on a Uniform Building Code recommended
overwhelmingly that the Illinois General Assembly adopt a
uniform, comprehensive, statewide building code. The task
force was created in 2005 to study the issue. AWC staff has
been involved in the effort since the beginning.
In its review, the task force believed that the adoption of
a uniform, comprehensive, statewide code creates greater protection
for the health, safety and welfare of Illinois residents, businesses
and property owners.
The task force investigated and discussed every aspect of the
built environment, as well as areas related to or affected
by the design and construction industries. This resulted in
a lengthy list of reasons why a statewide uniform code is of
critical importance for Illinois and its citizens.

| Louisiana
Homes Must Be Raised |
| Federal
Emergency Management Agency (FEMA) guidelines just released
are meant to help Louisiana residents rebuild in compliance
with drafts of new flood maps showing how high water would
rise during a once-in-a-100-year storm. These flood advisories
also detail how well the city’s levees would protect
residents. The guidelines recommend that thousands of homes
and businesses in the area be raised at least three feet. |
Property
owners who ignore the guidelines risk losing out on
government aid to rebuild and could miss an opportunity
for lower flood insurance premiums.
In drawing up the advisories, government experts took
into account the increasingly active hurricane seasons,
recent erosion of coastal land that |
|
|
acted
as a buffer against large storms, and the sinking of land
in parts of southern Louisiana. FEMA had delayed the release
of the advisories several times since the start of the year
as researchers incorporated new post-Katrina data.
Federal aid is available to pay for elevating houses, but many
home-owners could still be stuck with paying a portion of the
costs. Raising a house typically involves lifting it with hydraulic
jacks and constructing new wooden or steel supports.
In historic neighborhoods, many homes had already been built
several feet above ground and may not have to be raised at
all, even if they flooded during Katrina, because the advisories
assume that repaired levees will not break. Reportedly, the
White House’s new $2.5 billion request for flood protection,
if approved by Congress, would pay to replace flood walls and
raise levees surrounding 98 percent of the homes in the region.
The long-term work, which is expected to be completed by 2010,
includes the replacement of 30 miles of flood walls, said Lt.
Gen. Carl Strock of the Army Corps of Engineers.

| AWC’s
Online eQuiz System Registered |
| The
American Institute of Architects (AIA) has registered 15
of AWC’s popular online eCourses. This marks an important
milestone as many other institutes, associations, and licensing
entities recognize AIA registration for compliance with their
own membership’s continuing education requirements.
In the pilot study of AWC’s courses, leading up to
registration, 60 design professionals and building officials
took a total of 292 courses and eQuizzes, earning free continuing
education credits. In addition, twelve participants earned
free AWC Standards by completing all 15 eCourses/eQuizzes—a
total of 32.25 hours of training for each participant. |
 |
AWC
eCourses range in topics from wood building design
standards, building codes, fire performance, wood durability,
connections, wood as a material, and traditional and
engineered wood products; to specialized topics such
as lateral torsional stability of beams. eQuiz continuing
education hours range from 1.25 hours to as many as
4.0 hours for the longest course.
|
|
For
the registered courses listed at http://www.awc.org/HelpOutreach/eCourses/index.html,
the eCourse/eQuiz system will now operate on a pay-per-CEU/LU
basis. Students can still view eCourses and take eQuizzes
for free as often as they want. However, for a modest fee,
the student is offered an opportunity to obtain the CEU/LU
certificate for the online eCourse completed.
Another eQuiz pilot study will be announced in the third quarter
of 2006 for the 2005 NDS®, Lateral Torsional Buckling for
Beams, and Special Design Provisions for Wind and Seismic.

| Documentary “ Disaster
Resistant Homes” Features American Wood Council |
A
one-hour documentary developed for Public Broadcasting
Service (PBS) on disaster-resistant housing is currently
playing on television stations in the United States,
predominantly in the West and Midwest. The documentary
features on-air interviews of AF&PA technical
staff concerning safe and effective design for homes.
The show airs as the U.S. Southeast begins its post-Katrina,
post-Rita rebuilding process.
This
ITV website provides information about disaster-resistant
housing. The two half-hour documentary segments featuring
American Wood Council staff and their expertise can
be viewed here.
When
expertise on disaster resistant home design and construction
was needed for the program, the producers naturally
turned to AF&PA's American Wood Council. In the
program, viewers will be educated on proper design
for homes and small businesses that may be threatened
not only by hurricanes, but by earthquakes and wildfires
as well. The taping allowed AWC staff to share how
wood can play an important role in helping designers,
builders, and homeowners make their homes more disaster-resistant.
The
producers chose to include two segments of AWC staff,
one in the first half on wood

product
performance in earthquakes, and again in the second half
about the potential contribution to safety of available
innovative products. AF&PA’s Wood Frame Construction
Manual (WFCM) for One- and Two-Family Dwellings was
also mentioned as a good tool to be used for designing
more disaster-resistant homes.
In
the documentary, Robert Glowinski, Executive Director of
the American Wood Council, is quoted as saying, "[O]ne
of the benefits of using wood construction in an earthquake
area is that wood is very ductile. For example, when wind
blows a tree, the tree bends, it doesn't break...and wood
has the characteristic that it is very flexible and very
strong. So, in an earthquake that is shaking a building,
wood is a flexible material that actually performs very,
very well. And so, as long as you've used proper design
for your building in that earthquake, you will do very,
very well in a wood-frame building."
Additionally,
the industry's Wood Frame Construction Manual,
specifically developed by AF&PA for aiding design of
buildings in high wind, snow, or seismic areas, was highlighted.
The show’s narrator commented that “to help
homeowners figure out what to do to make their homes more
disaster-resistant and how to go about doing that, there
are many publications to choose from. Those include...the
American Wood Council's Wood Frame Construction Manual....”

| AWC Post-Katrina
Efforts Along the Gulf Coast |
As
Gulf Coast cleanup operations continue and rebuilding begins,
AWC continues its efforts to assist in the design and construction
of new buildings and to retain the market for wood products.
Although damage to most wood-frame buildings during Katrina
and Rita was the result of either storm surge or failure
to comply with existing building codes, emotional responses
to events like this often lead to unwarranted local restrictions
on wood products. To prevent this, in the last several months,
AWC has:
|
·
|
Contributed
free copies of AF&PA’s Wood Frame Construction
Manual (WFCM) to building code officials in the affected
areas.
|
·
|
Participated
in a conference for 350 Louisiana home builders, designers,
and code officials to educate them on the use of the WFCM.
|
·
|
Conducted
an all-day seminar in Houston to discuss the building code’s
requirements for lateral bracing and to introduce the WFCM to
participants.
|
·
|
Conducted
a series of WFCM training sessions in Florida and
other areas in the Southeast.
|
·
|
Impacted
legislation in both Louisiana and Mississippi that will adopt
statewide building codes, successfully eliminating provisions
that would adversely affect the wood industry. These provisions
were proposed by the insurance industry and were an attempt
to revamp an outdated Standard Building Code document that’s
still referenced in the International Building Codes
(IBC) without having to go through the International
Code Council (ICC) consensus process for revisions.
|
·
|
Held
conversations with the Institute for Building and Home Safety
(IBHS), an insurance industry organization, and successfully
convinced their representatives that construction-related
provisions being promoted by IBHS were unnecessarily restrictive.
These conversations could lead to joint creation of relatively
simple builders’ guides for use during reconstruction.
|
·
|
Began
work to produce a simplified version of the WFCM to
expand its appeal to non-technical users.
|
·
|
Additionally,
AWC is serving as a member of the ICC’s Hurricane Construction
Standards Committee. This committee is working to create
a prescriptive wind design document to replace the outdated
reference in the International Codes. Despite a number of
trade associations—that publish material-specific design
standards for their industries—objecting to this effort,
ICC appears determined to continue with the work. As a result,
AWC is actively participating in the activity. The committee’s
current goal is to have this prescriptive standard completed
by early 2007.

in the News in Texas |
After
staff from AWC and APA—The Engineered Wood Association
presented a program in Palestine, TX on building code requirements
for grade marking, preservative treated wood, finger-jointed
lumber, and span tables, the Palestine Herald reported
on the important event. Following are excerpts from the article:
|
| |
Around
60 building profes-sionals attended the City
of Palestine’s first East Texas Building
Conference at the Palestine Civic Center to learn
about the wood framing industry and updated building
codes. Speakers included engineered wood specialist
Ed Underwood and Dennis L. Pitts, regional manager
for the American Forest & Paper Association. “We’ve
been giving them instruction on how to do things
correctly to industry standards,” Pitts
said.
|
|
|
The
conference included details about the International Residential
Code for wood construction and the differences from the older
codes, as well as information on lumber and engineered wood
products. Information on common building problems such as avoiding
uneven roofs, squeaky floors and mold-moisture control also
were discussed.
Malakoff public works director Glen Herriage attended the conference to learn
more about building codes. “I learned about the different kinds of materials
and the actual process for treating wood,” Herriage said. “It’s
been helpful because I am pretty new to code enforcement.”
City of Palestine building official Warren Oakley said the building conference
was the first of its kind, but the city is planning future events. “We
want to continue to provide education for people here in Palestine.”
Oakley said the combined experience of the conference’s speakers—Pitts
and Underwood —made for an outstanding event. “These guys are the
best in the business. They are not only the ones out there training everyone,
but they also are the ones making the proposals to code groups—they help
write the code,” Oakley said.

2006
IBC Permits Wood Framing
to Support Structural Concrete
|
| One
important change to the 2006 International Building Code
(IBC) will permit wood framing to support structural
concrete, removing prescriptive restrictions on the use of
wood construction. The code change, initiated by AF&PA
and supported by the National Council of Structural Engineers |
 |
Associations
(NCSEA), was approved during the 2003/2004 code change
cycle.
Previous restrictions on wood framing supporting structural
concrete were carried-over from the 1997 Uniform
Building Code. These legacy provisions responded
to concerns about creep in horizontal wood members. However,
section 3.5.2 and Appendix F of the 2001 National
Design Specification® (NDS®) for
Wood Construction contain provisions to account
for time-dependent deformations (creep). These provisions
were introduced in the 1971 NDS as a general
criterion to limit |
|
long-term
deflection.
A second approved change clarified that restrictions on wood
supporting horizontal seismic loads from concrete/masonry were
for forces contributed by concrete/masonry walls. Prior to
this change, code language was being interpreted to prohibit
wood members from supporting horizontal seismic forces contributed
by brick veneer in buildings over two stories. Also, as concrete/masonry
construction is not limited to walls, this misinterpretation
could have included any other horizontal seismic forces from
concrete/masonry, such as from lightweight concrete floor toppings
or structural concrete floors.

design and building professionals who will be able
to use wood products in a safe and efficient manner.” Building
Construction major Ronald O’Brien said, “I
really appreciate your support in helping out our class
so that we may use these manuals at no cost (to us).
Your generosity will not be forgotten”…”none
of our homework assignments could have been completed
without them. The donation also helped with the financial
burden of purchasing textbooks; it would be nice if
there were more companies like Boise Corporation who
helped purchase important material for collegiate courses.
You’re being a leader and starting a trend!” wrote
