WebThe tributary-based unit diaphragm shear of 8 kips is to be transferred along the drag truss and must be called out on the framing plans. Shear walls of 10 feet and 8 feet are sectioned to accommodate for architectural features, which yields approximately 445 plf to be transferred into each shear wall below (Figure 5 ). Figure 5. WebSep 1, 2024 · It has become increasingly important to consider the relative stiffness of the diaphragms and shear walls, and the effects of multi-story shear walls as buildings become taller and more complex in shape.

WebDiaphragm – a flat structural unit acting like a deep, thin beam. The term is usually applied to roofs and floors designed to withstand lateral loads. Diaphragms are com-monly created by installing wood structural panels over roof or floor supports.
