屈曲约束支撑在侧向刚度不规则结构中的应用

Application of Buckling-restrained Braces in Irregular Structures with Lateral Stiffness

介绍了因结构层高差异较大导致侧向刚度不规则的工程设计难点,综合对比混凝土框架结构、框架–剪力墙结构、框架–普通钢支撑结构及框架–屈曲约束支撑结构对于此类工程的应用特点。对比结果表明框架–屈曲约束支撑结构适用此类工程。对框架–屈曲约束支撑结构进行模拟计算,分析侧向刚度及抗剪承载力计算结果,均满足规范要求。实现了框架–屈曲约束支撑结构体系从概念设计到模拟计算的过程。

This paper introduces the difficulty in engineering design of the lateral stiffness irregularity due to the high difference of structure layer.The application characteristics of concrete frame structure,frame-shear wall structure,frame-ordinary brace structure and frame-buckling restrained brace structure for such projects are compared.The comparison results show that the frame-buckling restrained brace structure is suitable for such projects.The frame-buckling restrained brace structure is simulated.The calculation results of the lateral stiffness and shear bearing capacity all meet the requirements of the code.The process from conceptual design to simulation calculation of frame-buckling restrained brace structure system.
