摘　　要：北京天文馆新馆采用以钢骨混凝土框架 -支撑结构为主的新型抗震结构体系。该工程结构体系复杂 ,应用ANSYS有限元分析程序对天文馆新馆进行了静、动力反应分析计算 ,为结构构件设计提供依据。着重讨论了地震作用下支撑构件的耗能作用 ,得出一些指导工程实践有益的结论。A novel seismic type of structural system called steel skeleton concrete frame-brace structure is used for Beijing new planetarimu,whose structural system is very complex.Calculation and analysis are carried out on static and dynamic responses for the engineering by means of finite element analysis program ANSYS,which provides a basis for design of structural members.Brace memebers are mainly discussed of dissipating energy under the action of earthquake.Finally some useful conclusions can be drawn to direct engineering practice.
