Seismic response analysis of a jointed precast concrete frame structure
Abstract：A nonlinear, transient dynamic analysis was performed as a pseudo-dynamic test of a jointed precast concrete frame structure. In these calculations beams and columns were simula ted by beam elements and a Takeda restoring force model. The beam to column connections were simulated by spring/clamp elements in nonlinear elastic restoring force model. A numeri- cal simulation employing series connected earthquake waves was used to estimate the effects from cumulative damage. The results show that the numerical simulation predicts values close to the test results： The differences between tests and calculations are less than 15.5~//oo. The effect of cumulative damage to the earthquake response is only distinct at the beginning of each test and becomes indistinguishable （less than 5 ~//00） when the earthquake waves increase to the peak.
