| 摘 要： | 本文对结构抗震分析的随机响应方法与反应谱方法作了比较.表明在两种方法的三维分析中,都应按CQC方法进行振型组合.文中还对于主要以第一振型参振的结构,给出按抗震规范的规定推算地面加速度功率谱密度的近似方法.

| Abstract: | In this paper, a comparison is made of structural aseismic analysis b means of the response spectrum method and the random response method. It is shown that in structural 3D aseismic analysis. CQC formulas of modal combination are more reasonable than SRSS formulas for both aseismic methods. And for structures in which first mode is induced by earthquake, an approximation of the auto-power spectral density of the ground acceleration is offered based on the response spectrum method stipulated by the Chinese aseisilic code of industrial and civi architectures. |
