| Abstract: | In this paper,local spectra of earthquake ground motions estimated by wavelet transform and pseudo exciation method are adopted to acquire the solutions for linear structural nonstationary random response,and several formulations of dynamic reliability based on the first-excursion failure criterion are employed to discuss the structural dynamic reliability.The comparison between stationary results and nonstationary ones is also carried out. |

| Keywords: | wavelet transform first-excursion failure dynamic reliability |
