英文摘要：

Based on available research results and simulation cases, applications and progresses of computer simulation technology in seismic design of structures, seismic assessment of existing structures, analysis of structural responses under extreme external actions and seismic planning or assessment of big area system in a city are introduced. Significance of using numerical methods which are appropriate to discontinuous and large deformation problems is emphasized. Significance of some measures to improve the application of computer simulation technology in structural seismic analysis, including establishing or upgrading the hysteresis model and multiparameter failure criteria of structural members, studying the damping mechanism of structures during decomposing, discussing the application of database technology in simulation system, developing analysis models for innovating structures and algorithms for analysis of earthquake responses of structures with initial damage, and introducing parallel technology is pointed out. Also, it is very important to verify the simulation results using engineering records or structural tests.
