DA 8 - Interior Shear Walls

5 pages (85 KB PDF)

This document describes how interior shear walls are designed to resist lateral loads. AWC's Wood Frame Construction Manual (WFCM) for One- and Two-Family Dwellings2001 Edition and Special Design Provisions for Wind and Seismic (Wind & Seismic), 2005 Edition, each provide design criteria for shear walls. Note that design assumptions are different for wind loads versus seismic loads. While wind loads act primarily on the “skin” of the structure, seismic loads are developed internally due to weight of materials and components in the structure. Therefore, certain provisions for interior shear walls may only apply to seismic loads and not wind loads.
