摘　　要：采用ANSYS有限元程序对巨型框架结构进行了抗震动力时程分析,讨论了巨型框架结构在多条地震波作用下的动力位移及内力等地震响应。计算结果表明,在几条不同的地震波作用下,巨型框架结构的主、次结构的地震反应是有差异的,就所讨论的巨型框架结构,El-centro地震波对结构的地震影响是最明显的;次框架的地震反应比主框架强烈,在结构抗震设计中不能忽略次框架的抗震问题。计算结果对巨型框架结构的抗震设计有较大的参考价值。Using the ANSYS finite element program,it was analyzed the earthquake resistance to the mega-frame and the mega-frame system′s displacement responses,such as dynamical displacement,internal force response,etc were also discussed. The calculated results show that the responses of earthquake are different in the main-frame and the sub-frame under the function of several different waves of earthquake,and El-centro wave is the most distinct.The responses of earthquake of the sub-frame are stronger than those of the main-frame.Therefore,the earthquake resistance of the sub-frame cannot be ignored in the design of construction.The calculation results have an important referential value to the design of earthquake resistance of mega-frames.
