中国美院良渚校区体育馆高位隔震研究

High-position seismic isolation of gymnasium in Liangzhu campus of China Academy of Art

中国美术学院良渚校区体育馆结构高度13.650m,采用框架结构体系,屋盖采用混凝土连续拱壳,大小拱交错布置。简要介绍了该工程的结构体系及结构弹性计算,采用支座隔震方法实现释放柱端弯矩、温度应力以及减小地震反应,利用SAP2000程序对整体结构进行了地震反应时程分析。

The structural height of gymnasium in Liangzhu campus of China Academy of Art is 13.650 m.Frame structure served as the based structure system.Multiple-span semi-circle shaped concrete shell,which was set alternately by larger radius and smaller ones,was used as the structural roof.The structural system and the elastic calculation results were introduced.Through analysis,it is found that bending moment,temperature-induced force was released and seismic response was reduced by means of installing isolator.Time history seismic response analysis of the structure,with or without isolation,were performed using SAP2000 program.
