An overview of 2018 International Building Code (IBC)and 2018 National Design Specification® (NDS®) for Wood Construction provisions related to the use of cross-laminated timber (CLT)will be provided that includes a step-by-step structural and fire design example for a roof and floor application. Additionally, the WoodWorks® Design Office’s Sizer program, version 12 (released January 2019) which enables CLT floor and roof design, will be used to demonstrate the structural design. Innovative wood products such as CLT are leading to a resurgence in heavy timber (Type IV) design and construction. These innovations are also making it possible for wood to be designed and built to taller heights and larger areas than what current codes permit. This has led to code change proposals for the 2021 IBC, expanding Type IV construction for tall “mass timber” buildings. Participants should find this presentation useful for current and future applications utilizing CLT in horizontal assemblies.

Learning Objectives: 

1. Discuss relevant CLT product manufacturing and design standards and identify where these standards are recognized in the IBC.
2. Consider the relevant structural design properties of CLT for floor and roof applications.
3. Discover how to design CLT floors to achieve serviceability goals related to deflection and creep.
4. Identify applications for using CLT and develop solutions using the highlighted resources.

Cross-laminated timber (CLT) has been in use worldwide for over 15 years, but most notably in Europe. Building with CLT has increased in popularity for many reasons including: just-in-time fabrication and job site delivery, speed and efficiency in construction, reduced job site noise and on-site labor force, substitution of high embodied materials with a renewable resource that sequesters carbon, and creating a living or work space that has the aesthetics of exposed wood.

The recent introduction of CLT in the 2015 National Design Specification® for Wood Construction (NDS®) and the 2015 International Building Code has opened up an exciting new chapter in wood construction. The use of CLT alone or in combination with other mass timber elements, such as glued laminated timber (GLT), nail laminated timber (NLT), or structural composite lumber (SCL), is becoming more common in buildings complying with the current code. There is also an effort underway by the International Code Council (ICC) to recognize the use of mass timber elements in taller, combustible construction through the work of the ICC Tall Wood Ad Hoc Committee. This presentation will provide an introduction to CLT including relevant design standards and code references. Examples of various mass timber buildings around the world will be provided and potential future code provisions relating to mass timber will also be discussed.

Fire testing to evaluate the performance of building materials and assemblies used in construction has been a requirement of building codes since the late 19th century. Early in the 20th century, versions of the ASTM E119 Standard Test Methods for Fire Tests of Building Construction and Materials were developed by the National Bureau of Standards as a means to compare the relative structural fire performance of materials and assemblies. Today, a science-based methodology exists, which allows designers to accurately calculate the behavior of wood exposed to an E119 time - temperature curve. Wood building elements are recognized for retaining their structural integrity despite the loss of fiber and cross-section due to charring.

With a rapidly growing interest in tall buildings constructed of mass timber, it became necessary to quantify the degree to which exposed timber contributes to a "real" compartment fire in order to establish appropriate building code requirements. During the work of the ICC Tall Wood Building Ad Hoc Committee (TWB), special test programs were developed and performed with the input of the fire service. Accordingly, a number of full-scale compartments constructed of mass timber building elements and furnished with real furniture and contents were fire tested. Results of these tests that were used by the ICC Tall Wood Building (TWB) Ad Hoc Committee in the development of proposed changes to the 2021 International Building Code will be presented.

Learning Objectives: 

1. Recognize the objectives of recent large-scale compartment fire testing in the U.S.
2. Describe the purpose of tests conducted by and findings of the NFPA Fire Protection Research Foundation at the National Institute of Standards and Technology (NIST) and the tests performed at the Bureau of Alcohol, Tobacco and Firearms (ATF) on behalf of the ICC TWB.
3. Evaluate and describe the outcomes of the ATF tests and contrast those to the outcomes of the FPRF tests.
4. Understand how testing is used to assess the added fire resistance time associated with non-combustible materials applied to mass timber elements in standardized E119 tests and be able to evaluate the results of those tests.

Adhesive bonding of wood laminations allows for the manufacture of large wood members. Adhesives used for this purpose must meet specified levels of resistance to heat at elevated temperatures. This performance is determined through testing. Code-referenced standards currently require such adhesives to pass a bond line shear test at elevated temperatures as a demonstration of this performance. The presentation will include an overview of the manufacturing of glued engineered wood products and the applicable code-referenced standards. During the work of the ICC Tall Wood Building Ad Hoc Committee (TWB), special test programs were developed and performed with the input of the fire service. New test protocols were developed to ensure the adhesive used in cross-laminated timber (CLT) will not result in the re-kindling of uncharred wood at the bond line. Background and the resulting test protocol for CLT will be presented.

Learning Objectives: 

1. Recognize how cross-laminated timber and other glued engineered wood products are manufactured.
2. Describe the compartment fire test results and circumstances that led to the development of a full-scale room fire protocol for qualifying adhesives used to manufacturer cross-laminated timber.

Building fire safety incorporates a combination of passive and active features. A passive fire safety feature may limit the height and area of the building, prescribe the use of fire-rated building elements or provide for adequate means of egress. Active fire safety features are those such as automatic fire detection or suppression systems that provide occupant notification, alarm transmittance and the ability to suppress fire growth until the fire service arrives. Codes are relying increasingly on active systems, since, with proper maintenance and alarm supervision, they have a high degree of reliability. This CEU covers the fundamentals of passive and active fire protection. It includes a summary of allowable wood use in buildings in accordance with the 2015 IBC, emphasizing the design flexibilities permitted for wood in nonresidential and multifamily construction.

When the International Building Code (IBC) was introduced in 2000, it consolidated three regional model building codes into one uniform code that has since been adopted by most jurisdictions. It increased the possibilities for wood construction by (among other things) recognizing additional fire protection techniques, consolidating the maximum allowable areas and heights from the three legacy codes into one (thus increasing what’s allowable in some jurisdictions), and allowing the use of wood in a wider range of building types. In subsequent versions of the IBC, even more opportunities have been created where additional fire protection features are used. This course serves to familiarize readers with provisions of the 2012 IBC relevant to wood construction.

Proper design of wood structures to resist high wind loads requires the correct use of wind load provisions and member design properties. A thorough understanding of the interaction between wind loads and material properties is important in the design process. Adjustments from reference wind conditions to extreme-value peak gusts require designers to make similar adjustments to design properties to ensure equivalent and economic designs. Wind load provisions have been developed for design of major structural elements using Main Wind-Force Resisting System (MWFRS) loads and secondary cladding elements using Component & Cladding (C&C) loads. Elements and subassemblies which receive loads both directly and as part of the main wind force resisting system, such as wall studs, must be checked independently for MWFRS loads and C&C loads. A load bearing stud wall design example based on the allowable stress design methods outlined in AWC's 2015 National Design Specification® (NDS®) for Wood Construction and 2015 Wood Frame Construction Manual along with ASCE 7-10 Minimum Design Loads for Buildings and Other Structures will demonstrate standard design checks for limit states of strength and deflection.

Fire testing to evaluate the performance of building materials and assemblies used in construction has been a requirement of building codes since the late 19th century. Early in the 20th century, versions of the ASTM E119 Standard Test Methods for Fire Tests of Building Construction and Materials were developed by the National Bureau of Standards as a means to compare the relative structural fire performance of materials and assemblies. Today, a science-based methodology exists, which allows designers to accurately calculate the behavior of wood exposed to an E119 time - temperature curve. Wood building elements are recognized for retaining their structural integrity despite the loss of fiber and cross-section due to charring.

With a rapidly growing interest in tall buildings constructed of mass timber, it became necessary to quantify the degree to which exposed timber contributes to a "real" compartment fire in order to establish appropriate building code requirements. During the work of the ICC Tall Wood Building Ad Hoc Committee (TWB), special test programs were developed and performed with the input of the fire service. Accordingly, a number of full-scale compartments constructed of mass timber building elements and furnished with real furniture and contents were fire tested. Results of these tests that were used by the ICC Tall Wood Building (TWB) Ad Hoc Committee in the development of proposed changes to the 2021 International Building Code will be presented.

Learning Objectives:

Adhesive bonding of wood laminations allows for the manufacture of large wood members. Adhesives used for this purpose must meet specified levels of resistance to heat at elevated temperatures. This performance is determined through testing. Code-referenced standards currently require such adhesives to pass a bond line shear test at elevated temperatures as a demonstration of this performance. The presentation will include an overview of the manufacturing of glued engineered wood products and the applicable code-referenced standards. During the work of the ICC Tall Wood Building Ad Hoc Committee (TWB), special test programs were developed and performed with the input of the fire service. New test protocols were developed to ensure the adhesive used in cross-laminated timber (CLT) will not result in the re-kindling of uncharred wood at the bond line. Background and the resulting test protocol for CLT will be presented.

Increasingly, wood from sustainably managed forests is viewed as a responsible choice—for a number of reasons. Wood grows naturally by harnessing energy from the sun, absorbing carbon dioxide and releasing oxygen. It is renewable and a carbon sink, and outperforms other materials in terms of embodied energy, air and water pollution, and other impact indicators. But what about the forest? The benefits above notwithstanding, how can building designers be sure that specifying wood doesn’t negatively impact the North American forest resource? As this course will demonstrate, the answer to that question has several elements.

Learning Objectives: 

1. Evaluate the use of wood as a construction material in the context of long-term forest sustainability as well as attributes such as low embodied energy and light carbon footprint.
2. Discuss forest sustainability measures such as biodiversity, soil and water quality, and harvest vs. net growth.
3. Examine the concept that using wood in buildings provides an incentive to landowners to keep forested lands forested instead of converting them to uses such as urban development.
4. Compare the carbon benefits of an unmanaged forest vs. a managed forestwhere timber is used for wood buildings.
