P2: For the structure shown in FIGURE P9.9 (the same structure as in P3 in Assignment 9, and P1 in Assignment 10), subjected to harmonic forces h(t) = sin(0.15t), p2(t) = 3sin(t),Ps(t) = 8sin(St) write the equations for the drift of each floor and the base shear. Plot these for 10T1, where T is the first mode period. repeat part a, but with the assumption of 5% classical damping for modes 1 and 2. a) b) Assume E-29000 ksi and columns bend about their strong axis. wou 0.5 kip/ft Rigid 20ft W14x82 W14×53 WDL21.0 kip/ft Rigid WDL2 w14×53 20ft |w14×99 W14x82 WDL3 WDls -1.0 kip/ft WDLs Rigid 25 ft 1 w14×132 W14X99 W14x82 W14×53 25 ft 50 ft 25ft Figure P9.9
