Study on Long-Period Inelastic Spectra of near-Fault Pulse-Like Strong Ground Modeled Using Analytical Model

Because the parameters of Mavroeidis analytical model of pulse-like strong ground motion have an unambiguous physical meaning, the analytical model has been calibrated using a large number of actual near-field ground-motion records, and It can successfully simulate available near-fault pulse-like acceleration time histories, in this paper, we synthesize ground motions using the model to investigate elasto-plastic earthquake responses of long period single-degree-of-freedom system to the pulse-like ground motions, revealing the elasto-plastic long-period ground motion characteristics of pulse-like ground motion.
