The above link explains how to define a wind load using wind definition.
I have 2 comments/inquiries about it:
1) @ 5:12, the input was L=75 ft and B = 90 ft but the geometry @ 1:17 states that along Global X, L=90 ft and B = 75 ft. Please clarify this. I believe the input should be reciprocated for L and B windward and leeward directions but kept the same for the Sidewalls direction.
2) @8:33 For the sidewalls of the wind +X direction, the Building Length along the direction of wind should be (L=70 FT) & Building Length Normal along the direction of wind (B=90FT) as the wind acting on the sidewalls are normal to the windward and leeward direction and therefore the L,B are not the same as the windward and leeward.
