Given: The single-story commercial building in Fig. 9.A. The wood structural panel is
thick 32/16 span-rated sheathing unblocked. Nails are 8d common. Critical lateral forces (wind) are
Find: a. For the transverse direction:
1. Roof diaphragm unit shear
2. Panel load case (state criteria)
3. Required nailing and tabulated ASD allowable shear (from IBC) or tabulated nominal shear (from SDPWS) adjusted to ASD capacity per SDPWS.
4. Unit shear due to LRFD load combinations, required nailing and tabulated nominal shear (from SDPWS) adjusted to LRFD capacity per SDPWS.
b. For the longitudinal direction:
1. Roof diaphragm unit shear
2. Panel load case (state criteria)
3. Required nailing and tabulated ASD allowable shear (from IBC) or tabulated nominal shear (from SDPWS) adjusted to ASD capacity per SDPWS.
4. Unit shear due to LRFD load combinations, required nailing and tabulated nominal shear (from SDPWS) adjusted to LRFD capacity per SDPWS.
c. If blocking is not required, do the edges of the panel need some other type of edge support?
