摘要

介绍了屈曲约束支撑在上海东方体育中心综合馆中的应用。综合馆拱架平面外每侧设置了三榀大型支撑框架。为满足建筑对截面的要求,同时避免支撑杆件在结构承受水平荷载时受压屈曲先于强度屈服,提高支撑框架在罕遇地震中的耗能性能,在竖向支撑框架中采用了屈曲约束支撑。对结构设置屈曲约束支撑的优点、总体和节点设计方法以及安装施工手段进行了阐述,对其在结构设计中的应用和推广具有现实意义。
The application of buckling restrained braces in Shanghai Oriental Sports Center General Gymnasium was presented.Three large support frameworks were set up on each side of General Gymnasium out of arch plan.To meet the construction requirements of section,avoid supporting bar pieces to be buckling under pressure before strength yield while withstand lateral loads,and improve energy dissipation capacity of the supporting frame in rare earthquake,the buckling restrained braces were used in vertical support framework.The advantage of the buckling restrained braces,design method of integral structure and node,methods of erection construction,were described.There will have practical significance of its application in structural design and promotion.
