WebA diaphragm acts in a manner analogous to a deep beam or girder, where the panels act as a “web,” resisting shear, while the diaphragm edge members perform the function of “flanges,” resisting bending stresses. These edge mem-bers are commonly called chords in diaphragm design, and may be joists, ledgers, trusses, bond beams, studs, top 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 …

WebThe chords, collectors and their connections, (y) and (z) in Figure 5, and other structural components transferring shear, such as the CLT panels themselves, have different design requirements.These components and connections must be designed to a higher required capacity using a force increase factor applied to the diaphragm design force. WebThe deficiency is in the strength of the diaphragm in the vicinity of corners. Evaluate the chord/collector requirements at the reentrant corners and other locations of plan irregularities by applying the maximum of the diaphragm force and the calculated story force to a model of the isolated diaphragm.
