In the 2024 International Building Code (IBC) and 2024 International Fire Code (IFC), several changes were made to mass timber provisions, including the following:
…Proper design of bearing intersections between mass timber members is critical to the overall success of a mass timber project. The details of these intersections have a significant effect on cost and schedule. This article focuses on the multi-story column condition, where loads from the column above need to be transferred down through the beam-column intersection, and the beams are supported using a bearing pocket instead of a bearing hanger (Figure 1).
…The 2021 Edition of Special Design Provisions for Wind and Seismic (SDPWS) was approved as an American National Standard on July 22, 2020, with the designation ANSI/AWC SDPWS-2021 (Figure 1). The 2021 SDPWS was developed by the American Wood Council’s (AWC’s) Wood Design Standards Committee (WDSC) and contains provisions for the design of wood members, fasteners, and assemblies to resist wind and seismic forces. Notable revisions are summarized below (also see Table 1 online for a summary of changes by Chapter):
