So I'm designing a building that is using precast concrete shear walls to resist seismic and wind loads. Because of the heavy nature of these walls, the seismic story forces are turning out to be fairly large. When designing the diaphragm deck connections (metal roof deck), can you ignore the seismic forces resulting from the weight of the shear wall parallel to the direction of the loading since none of that wall weight will actually be transferring through the diaphragm?
