摘要
利用小波分析估计的地震动局部谱，采用虚拟激励法求得了线性结构非平稳随机响应，结合基于首超破坏准则的几种动力可靠度表达式，对结构的动力可靠度进行了讨论，并与平稳响应的情况进行了比较。
In this paper, local spectra of earthquake ground motions estimated by wavelet trans form 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.
