Question

Consider the five-story building shown in the figure.The average weights of the floor and roof are 80 lb/ft and 70 lb/ft, respectively The values of SDS and Spiare equal to 0.9 g and 0.4 g. respectively. Since steel moment frames are used in the north-south direction to resist the seismic forces, the value of Requals 8. Compute the seismic base shear V. Then, distribute the base shear along the height of the bulding A 4@25' 100 Plan (a) roof 20 5 4 15 13 2 Building Section wind pressures in lb/ft2 (c) (b) 5 @ 12'= 60' 3 @ 20'= ( The seismic base shear Vof the building is kips.

The seismic base shear Fx on the third floor is The seismic base shear Fx on the second floor is kips.
