CLT Connection Design Provisions in the 2018 NDS

The addition of cross-laminated timber (CLT) to AWC’s National Design Specification® (NDS®) and upcoming changes in the 2021 International Building Code (IBC) has given engineers exciting design options never before available in US building codes and standards. New provisions were introduced for CLT connection design in the 2015 edition of the NDS and clarified in the 2018 edition. This presentation will provide background on relevant NDS provisions governing structural design of connections for CLT members, present a design example, and discuss fire protection requirements specified in NDS and AWC’s newly updated Technical Report 10 – Calculating the Fire Resistance of Wood Members and Assemblies (TR10).
