A five-story building plan is shown in figure (a). Following the ASCE standard, the wind pressure along the height on the windward side has been established as shown in the

figure (c). Considering the windward pressure in the east-west direction, use the tributary area concept to compute the resultant wind force ateach floor level. The resultant wind force at the roof is The resultant wind force at the fifth floor is The resultant wind force at the fourth floor is The resultant wind force at the third floor is The resultant wind force at the second floor is
