The American Wood Council (AWC) released an updated “Technical Report 10 (TR10), Calculating the Fire Resistance of Wood Members and Assemblies.”
“The emergence of mass timber as a competitive product in the construction marketplace has increased designers’ interest in the fire performance of mass timber,” said Brad Douglas, AWC vice president of engineering, in a news release. “Recognizing that increased interest, the principal changes to this edition provide new examples and background on mass timber members and assemblies.
“TR10 will assist in the design of efficient and building-code-compliant load-bearing wood members and assemblies by providing background information, examples of calculations, and end-use tables for a variety of structural wood products.”
Revisions include expansion of design provisions for calculating the contribution of gypsum board protection, and updated calculation of thermal separation times.
