6) For the steel-framed office building shown below, find the design wind loads that should be applied to each floor in the North/South direction.  The structure is located in Detroit, MI.  It is on flat ground in a dense urban environment.  Also find base shear and overturning moment.

7) For the steel-framed office building shown below, find the design seismic loads that should be applied to each floor in the North/South direction.  The structure is located in Detroit, MI.  It is on flat ground in a dense urban environment.  S_s is 0.12, S₁ is 0.05.  The dead load is estimated to be 60 psf for all floors.  Also find base shear and overturning moment.  Which would control, wind or seismic for this structure?
