Experimental studies of cyclic performance of wood-frame shear walls give insight into structural performance and have informed recent changes implemented in the 2021 Special Design Provisions for Wind and Seismic (SDPWS). Experimental results for 10d short nails, shear wall end post details, and gypsum wallboard contribution to shear wall strength and stiffness are summarized. SDPWS requirements and commentary guidance relative to the tested systems will also be discussed.

Learning Objectives:

• Recognize select SDPWS provisions for design of wood frame shear walls
• Describe wood frame shear wall behavior under cyclic loading
• Identify shear wall detailing that provides better performance
• Discuss typical wood frame shear wall failure modes
