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).

Learning Objectives:

1. Recognize relevant NDS provisions for designing CLT connections
2. Utilize requirements for using non-standard fasteners in conjunction with the 2018 IBC
3. Calculate fastener capacity in shear and withdrawal for CLT connections
4. Describe fire protection requirements for CLT connections
