1 - Details for Conventional Wood Frame Construction
(formerly T11 Manual for Wood Frame Construction)
(54 pages, 1.4 Mb pdf) June 2001
WCD #1 is a comprehensive
summary of rules and guidelines for the proper construction of wood
frame buildings built to conventional construction provisions in
the model building codes. WCD #1 includes information on various
types of construction, framing systems, fire and draftstopping, protection
against termites and decay, fastenings, insulation, and materials,
as well as a series of figures included to illustrate proper framing
techniques.
Today, some building codes may require a more rigorous structural
design methodology than is associated with conventional construction.
This requirement may result from a need for better building performance
when the structure is exposed to moderate-to-high wind, seismic,
and snow loads. AF&PA publishes the Wood
Frame Construction Manual for One- and Two-Family Dwellings to
provide solutions based on engineering analysis, in accordance
with recognized national codes and standards. Like conventional
construction, the engineered solutions are provided in a prescriptive
format.

WCD 2 - Tongue and Groove Roof Decking
(12 pages, 2.3 Mb pdf) February 2004
Timber tongue
and groove decking is a specialty lumber product, constituting
an important part of modern timber construction, that can be
used for many applications to provide an all-wood appearance.
Nominal three and four inch decking is especially well adapted
for use with glued laminated arches and girders and is easily
and quickly erected. This document contains all that's needed
to design and construct tongue and groove wood roof decking,
including span and load tables.

4 - Plank-And-Beam Framing for Residential Buildings
(40 pages, 1.8 Mb pdf) April 2003
The plank-and-beam
method for framing floors and roofs has been used in heavy
timber buildings for many years. The adaptation of this system
to residential construction has raised many technical questions
from designers and builders concerning the details of application.
This publication presents technical data that will be helpful
to students, architects, engineers and builders. It contains
information pertaining to principles of design, advantages
and limitations, construction details, and structural requirements
for the plank-and-beam method of framing, including span and
load tables.

WCD 5 - Heavy Timber Construction
(17 pages, 2.8 Mb pdf) February 2004
Heavy timber
construction is one of the oldest types of buildings used in
the development of this country. Its superior performance has
been demonstrated in thousands of buildings during the past hundred
and fifty years, many of which are still in satisfactory use.
As originally conceived, the heavy timber building was a multi-story
structure, designed and used primarily for industrial and storage
purposes. Today, its use has been expanded to include many other
occupancies. It is commonly used for assembly and mercantile
buildings, such as schools, churches, auditoriums, gymnasiums,
supermarkets, and for various other structures.
This publication defines the minimum requirements for heavy timber
construction, and provides illustrations of good construction details.
These are recommended to the architect and builder as a guide in
developing a safe and economical form of construction.

6 - Design of Wood Frame Structures for Permanence
(23 pages, 1.3
Mb pdf) February 2006
Design of
durable structures is the result of careful planning and understanding
of loads and forces that will likely act upon a building during
its lifetime. If these key elements are not taken into consideration,
the designer may compromise the ability of the structure to remain
fully functional over extended periods of time.
When properly
designed, wood frame structures will resist damage by moisture
and living organisms. Recommendations for control of moisture
and protection against decay and insect infestations are contained
in this document. Many of the recommendations are established
practice among architects, engineers, and builders.
Protection
of wood frame structures to provide maximum service-life involves
four methods of control, which can be handled by proper design
and construction: (1) control moisture content of wood, (2) provide
effective termite controls, (3) use of durable materials such
as naturally durable or pressure treated wood, and (4) quality
assurance.
