When a moment frame does not exceed 12 stories in height and the story height is at least 10 ft, the ASCE standard provides a simpler expression to compute the approximate fundamental period: T = 0.1N where N = number of stories. Recompute T with the above expression and compare it with that obtained from Problem P2.16. Which method produces a larger seismic base shear?
Problem 2.16
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.
