Drag truss/diaphragm design?
Drag truss/diaphragm design?
(OP)
Given:
2-story building.
Wind controlled design.
Shearwall located under drag truss.
Is it necessary to design the drag truss to transfer the roof wind loads (wind loading on roof only) OR does it need to transfer the diaphragm loads (wind loading on roof + half of 2nd floor wall height)?
I know that the shearwall load at the top of the 2nd floor is the diaphragm load, but is it necessary to design my drag truss for this total load?

If there is a shear wall "B" below shear wall "A", then that shear wall would see roof plus second floor lateral forces, but not shear wall "A".
