摘要
对随机结构动力分析方法，包括随机模拟法、摄动随机有限元法、动态随机有限元法和正交展开法等进行了评述，介绍了该领域内的研究进展，并讨论了研究中存在的问题以及发展方向．
Various approaches of random dynamic response analysis of structures with stochastic parameters, including random simulation, perturbation stochastic finite element method, dynamic stochastic finite element method and orthogonal expansion, are comprehensively discussed in this paper. The new advances of random dynamic response analysis of structures with stochastic parameters are reviewed. The existing problems and the future improvement trends are also briefly outlined.
