Consider the five-story building shown in Figure P2.10. The average weights of the floor and roof are 90 lb/ft 2 and 70 lb/ft 2 , respectively. The values of S DS and S D1 are equal to 0.9g and 0.4g, 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.
