［摘要］目前屈曲约束支撑广泛用于新建和加固的钢筋混凝土框架结构中，构成屈曲约束支撑-钢筋混凝土框架结构。鉴于这种结构的设计方法未在规范中明确规定，在试验研究和设计实践的基础上，提出一些设计建议, 包括设计时需根据屈曲约束支撑性能采取不同的设计方法、结构适用高度、屈曲约束支撑布置方法和要求、小震作用下屈曲约束支撑计算假定、结构楼层位移角限值、屈曲约束支撑根据不同性能需采取的不同检验要求、屈曲约束支撑与结构的连接设计和钢筋混凝土框架的抗震措施。

Abstract:At present, buckling restrained braces are widely used in new and strengthened reinforced concrete frame structures, which becomes the reinforced concrete frame structure with buckling restrained braces. In view of the fact that the design method of this kind of structure is not clearly specified in the code. Some design recommendations on the basis of experimental research and design practice was proposed, which includes different design methods should be adopted according to the performance of buckling restrained braces, applicable height of structure, arrangement method and requirements of buckling restrained braces, calculation assumption of buckling restrained braces under small earthquake, limit value of floor displacement angle, different inspection requirements of buckling restrained braces according to different performance, connection design between braces and structure, seismic measures of reinforced concrete frame.

Keywords:buckling restrained brace;reinforced concrete frame structure;seismic reinforcement;energy dissipation
