摘　　要：介绍了地震反应分析理论和方法发展的基本概况,并对弹塑性地震反应分析中采用的纤维梁柱单元及国外新近出现的IDA方法进行了详细的说明。在此基础上,对能够有效解决弹塑性地震反应分析计算的OpenSEES软件系统做了介绍。The research and development of theories and methods about seismic analyses of bridge structnres are introduced, and fiber beam-column element and IDA （ Incremental Dynamic Analysis） that is put up recently are expounded in detail. Based on facts mentioned abvoe, the OpenSEES software that could perform the elastic-plastic seismic analyses of the bridges is recommended.
