Consider the five-story building shown in the figure.The average weights of the floor and roof are 100 Ib/ft and 70 Ib/it respectively. The values of Sps and Sp1 are 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 R equals 8. Compute the seismic base shear V. Then, distribute the base shear along the height of the building. The seismic base shear Vof the building is The seismic base shear Fy on the roof is The seismic base shear Fx on the fifth floor is The seismic base shear Fy on the fourth floor is The seismic base shear Fx on the third floor is The seismic base shear Fy on the second floor is
