摘要
针对精细时程积分法在大型结构地震响应中的分析,提出了扩阶方法以及状态方程精细时程积分法的结合,编制了程序;用该方法对高层框架结构受地震荷载作用下的响应进行了计算,计算结果表明,考虑参数随机对框架结构动态响应有显著影响;计算结果同Monte-Carlo法的结果进行了比较,前者计算效率较高,适用于工程计算.图9,参8.
To aim at application of precise time integration method in earthquake response analysis of large-scale structures, the new methods was presented that included expanded order system method and direct integration method of state equation. The program was developed and used to analyze the response of frame structures driven by earthquake. Numerical results indicate that uncertain physical parameters influence response deeply. The results of comparison between the new method and Monte-Carlo method show that the former has high efficiency, and adapt to operation of engineering. 9figs, 8refs.
