Diaphragms and shear walls
WebThe shear being transferred into the shear walls at lines A and G is the perpendicular component of the direct shear and is not additive. To better understand this, consider the shear on a small square section of the roof diaphragm, as shown in Figure 1a.

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. WebA diaphragm wall is a rectangular section that is built in place beneath the soil. These walls are constructed panel by panel both interlocked to guarantee structural stability and water tightness. The diaphragm walls’ thickness can range from 60 cm to 150 cm, and their width can be between 2.0 and 3.5 meters.

Cyclic testing has shown that nails tend to bend and withdraw slightly rather than breaking and withdrawing completely. Even when partially withdrawn, nails retain some reserve withdrawal resistance.
WebNov 1, 2024 · All edges of diaphragms must have boundary members consisting of drag struts, chords, collectors, or vertical lateral force-resisting elements. Boundary members include chords and drag struts at diaphragms and shear wall perimeters, interior openings, discontinuities, and re-entrant corners. WebDiaphragms are com- monly created by installing wood structural panels over roof or floor supports. Shear Wall – a vertical, cantilevered diaphragm that is constructed to resist lateral shear loads by fastening wood structural panels over wall framing.
