摘要
文中介绍结构平稳和非平稳随机地震响应分析精确高效的虚拟激励法，无论是完全相干还是部分相干，比例阻尼还是非比例阻尼，都能方便地处理大跨度及多点输入问题。
This paper introduces the precise and high-effective pseudo-exicitation analysis method for stationary and nonstationary random seismic response of structures,no matter what is completely coherent or partially coherent,proportional damping or nonproportional damping,it can all easily handle the issues of large spans and multi-point inputs.
