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.) 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. flowers to plant in spring in south africa https://rockadollardining.com
