Diaphragm shear

WebOct 28, 2003 · The floor diaphragm shear should be transferred into the collector beams down each side of the diaphragm. As the shear is built up along the collector, you have an increasing axial tension/compression as the collectors approach the brace. WebOn large diaphragms, it is common to vary the deck gauge and connection patterns across the roof as the shear forces change. Chord Forces The sidewall wind pressure creates bending moment in the roof. This moment can be calculated by assuming the roof as a simply supported beam between shear walls.

WebA diaphragm is a flat structural unit acting like a deep, thin beam. The term “diaphragm” is usually applied to roofs and floors. A shear wall, however, is a vertical, cantilevered diaphragm. A diaphragm structure results when a series of such vertical and horizontal diaphragms are properly tied together to form a structural unit. (See Figure 1.) WebThe lateral diaphragm forces need to be transferred into the walls. Often, the attachment of the blocking or rim joist to the walls is inadequate or missing. New shear anchors can be installed to transfer the horizontal diaphragm forces into the walls.
