WebMar 2, 2024 · In theory, if your diaphragm is perfectly rigid and can't deform then you don't have a chord force. No strain = no stress. Would think in practice if you qualify as a rigid diaphragm under ASCE 7's definition then your chord force would be pretty small anyways. KootK (Structural) 3 Mar 18 01:03 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.)
