This presentation will include background on the ICC Tall Wood Building (TWB) Ad Hoc Committee, which was created in 2016, reviewed voluminous materials regarding tall wood buildings, including results of various testing around the world, as well as studies domestically in support of the TWB charge to conduct a thorough review of the science of tall wood. An overview of the TWB research which developed its own test scenario(s) to substantiate code change proposals (testing was carried out at ATF labs); and worked to develop a comprehensive set of technically-substantiated code changes for consideration during the ICC 2018 Group A code development process. The resulting approved changes to the 2021 International Building Code allow for construction of mass timber buildings with larger heights and areas than is currently permitted in Types III, IV, and V construction.
1. Identify the make-up of the TWB Ad Hoc Committee.
2. Recite the process used to reach consensus on proposed code changes.
3. Recognize how new types of construction compare with existing types of construction in the International Building Code and specify the inherent differences and conservative approaches for the new construction types.
4. Evaluate the fire resistance requirements for tall mass timber building elements.
