WebMar 3, 2008 · At the "chord" edge of the diaphragm (the edge of our "element"), this horizontal shear has to be resisted (by something) for stability. That is where the "chord" comes in. For a simple span diaphragm, the vertical shear at the support would be wL/2d (lbs/ft), where d is the depth of the diaphragm.
