| Abstract: | To aim at application of precise time integration method in earthquake response analysis of large - scale structures, a new method consisting of expanded order system method and direct integration of state equation method is presented in this paper. A program is developed and used in analyzing the response of frame structures at Shanghai zone. Numerical results show that taking account of uncertain load parameters deeply influenceing responsers, this method has high precision and efficiency, and is adapted to the engineering calculation. |
