The diaphragm between the walls in a shear line would essentially remain rigid, and just bend between the shear lines themselves. Still, we agree that our initial design was a little liberal in what could be considered the same ... WebShear wall stiffness can have a significant effect on the distribution of shear forces through the diaphragm. It has become increasingly difficult to find exterior walls that can be used as shear walls due to diminishing wall lengths, larger openings, and building offsets.
