摘　　要：以南京火车站的站房结构为模型,使用一致激励和多点激励计算了结构在不同激励状况下的结构响应。计算结果表明,一致激励和多维多点的计算结果有很大区别。计算大跨度结构在大震作用下的结构响应(大震不倒)是十分重要的,给出在大震作用下计算空间结构弹塑性分析的方法。使用时程法计算了南京站网架在大震作用下的结构反应,计算结果已用于工程实际。The seismic responses of structure of Nanjing Station are numerically simulated under the uniform excitation and the traveling-wave excitation.The results show that the internal forces of structural bars may be greatly changed by considering the spatial effect of earthquake motion.It is very important to evaluate its safety（non-collapse） during severe earthquake.The analysis method for long span structures during severe earthquake is given.The reaction of Nanjing station structure during severer earthquake is calculated through time history method,and the result is satisfactory and useful to the design work.
