摘要
在结构基本指标一致的前提下,对比分析高层钢框架-中心支撑结构采用普通支撑和屈曲约束支撑的经济性,确定合理方案。通过时程计算,分析结构采用屈曲约束支撑减震方案后,结构的整体抗震性能和屈曲约束支撑的工作状态。结果表明,屈曲约束支撑应用于钢结构,能够充分发挥其塑性耗能的能力,有效保护主体结构。
On the premise of the same basic structural indexes,the economy of using common brace and buckling-restrained brace in high-rise steel frame-central braced structure is compared,and the reasonable scheme is determined.Through time-history calculation,the whole seismic performance and the working state of buckling-restrained brace are analyzed for the buckling-restrained brace structure.The results shows that the buckling-restrained brace can fully exert its plastic energy dissipation ability and protect the main structure effectively when it is applied to the steel structure.
