WebNov 1, 2024 · All edges of diaphragms must have boundary members consisting of drag struts, chords, collectors, or vertical lateral force-resisting elements. Boundary members include chords and drag struts at … WebBackground and Applications A drag truss, sometimes referred to as a “collector” truss, is a single- or multi-ply pre-engineered truss designed to “drag,” distribute, and transfer shear loads generated within the plane of …
WebThere still needs to be a chord at gridline C for that diaphragm when loaded in the left-right direction. The collector is for dragging the load into the shear wall when you are analyzing lateral load in the up-down direction. Sometimes, a member can act as a collector in one direction and a chord in the other. 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.
