Design/Construction Guide: Diaphragms and Shear Walls
www.osbpanel.orgdiaphragms and shear walls are used in the lateral design of a building, the structural system is termed a “box sys-tem.” Shear walls provide reactions for the roof and floor diaphragms, and transmit the forces into the foundation. An accurate method for engi-neering diaphragms has evolved from analytic mod-els and extensive testing, and
