3.7.4 Elasto-Plastic and Bilinear Response Comparisons

The effects of various ps on response behavior are shown for the rigid frame shown in Figure 3.38. Assume EI = 1000 kip in.2 (2.8697 kNm2), M = 2 x 10~4 ks2/in. (35.0236 Ns2/m), h = 10 ft (3.048m), I = 20 ft (6.096m), F(t) = 0.02sin(pf)k (88.96sin(pt)N), p = 0.05, and ultimate moment capacity Mp = 0.2 kin. (22.59584 Nm). The initial conditions are x0 = Xq = Xq = 0. The effect of ps on xs
