CLT Diaphragm Design for Wind and Seismic Resistance

Technical resource addressing the design of CLT diaphragms following the new provisions in SDPWS 2021. Covers overview of new CLT diaphragm provisions, implementation recommendations, design loads and force increase factors, connection requirements using dowel-type fasteners, detailing considerations for boundary elements, and diaphragm flexibility analysis. Addresses coordination with ASCE 7-16 requirements, collector and chord design, panel-to-panel connection details, and provides practical guidance for practicing engineers implementing CLT diaphragm design in mass timber projects.
