| Abstract: | Stochastic seismic response is given for a nonlinear hysteretic system with multi degree of freedom. The earthquake motion is simulated as a stationary filtered non white noise. Combining statistical linearization and complex eigenvalues, use is made of a degrading hysteretic restoring force of the Boue Wen BaberNoori model in random vibration of multi degree of freedom system. Analysed is the dynamic reliability of the system using a damage index parameter that accounts for ductility and energy dissipated in the structure. |
