(a) Problem description
(b) SDOF system model
(c) Response spectrum computations
From the triple Kalamata 1986 earthquake response spectrum given in Figure 2.29, we have:
●maximum relative displacement is u=y−y =1.8 cm;
s
●maximum velocity is y=35 cm/sec;
2
●maximum acceleration is ÿ=0.7 g=6.87 m/sec ;
●maximum column shear is V=(ku)/4=16,600(0.018)/4=74.7 kN; and
2
●maximum column shear stress is τ=V/A=74.7/(0.4 )=467 kN/m 2
