摘要
静力弹塑性(Pushover)分析法在高层结构的抗震设计和结构性能评估中有着广泛的应用,给出了Pushover分析法的基本原理,介绍了MDOF体系到SDOF体系的转换方法,侧向荷载分布方式及目标位移的确定等,并用该方法对15层框架结构进行了分析。结果表明,Pushover法对规则结构的非弹性行为作出可靠的评估,有很高的精确性,应用前景广泛。
The pushover analysis method has been extensively used in earthquake design and evaluation of tall buildings.It was given the basic principle of pushover analysis method.The content includes the method to convert MDOF system to SDOF system.lateral load patterns and method to obtain target displacement and so on.After that it was analysed a fifteen-floor frame structure by pushover method.The result indicates that the pushover analysis method can evaluate the inelastic behavior of regular structure credibly.The pushover analysis method has high accuracy and wide foreground in application.
