Leeward vs Windward Loads

Shearwalls calculates and displays both leeward (suction) and windward loads. However, for all surfaces in the ASCE C&C method, the leeward criterion is greater than the windward one for tributary widths < 10 feet, therefore the suction C&C loads govern for both nail withdrawal design and plywood bending strength, and it is the positive internal pressures that are considered for C&C loads.
