WebTension and compression chord forces are developed at the perimeter of the floor diaphragm due to the lateral loads. Typi-cally, the floor slab concrete can resist the compression chord forces. Tension chord forces can be resisted by the spandrel steel beams, continuous steel closure plates, or by reinforcing steel within the concrete slab. somalia welthungerWebDiaphragm boundary elements (chords and collectors) are often glulam timber beams.

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.

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.)
