| Abstract: | 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. |
