Abstract

Ground motion duration can significantly influence the dynamic response and cumulative damage of structures. To investigate the influence of ground motion duration on structures with pinch degradation behavior, this study used the seismic design spectra as the target spectra, and the spectra matching method to obtain 221 spectral-equivalent ground motion records, and used them as the inputs to calculate the damage spectra of the hysteretic model with pinch-degradation behavior for four different strength reduction coefficients. The results of analyzing the damage spectra show that the structural damage of the pinch hysteresis model increases with the increase of duration, and the influence of ground motion duration on structural damage first increases and then decreases with the increase of period.
