［摘要］通过钢支撑-混凝土框架结构体系、RC框架结构体系和框架-剪力墙结构体系的对比分析，结果表明，钢支撑-混凝土框架结构提高了结构侧移刚度，降低了结构自振周期，减小了结构侧移和层间位移角；钢支撑分担了部分楼层剪力，改变了结构的内力分布特点，降低了结构构件的内力，为双重抗侧力结构体系，具有良好的抗震性能，可应用于高烈度地区以及加固改造工程中。

Abstract:Through the comparative analysis of steel braced concrete frame structure system, RC frame structure system and frame-shear wall structure system, the steel braced concrete frame structure system improves the lateral  stiffness of the structure, reduces the natural vibration period of the structure, and reduces the lateral displacement and story drift ratio. The steel brace shares part of the floor shear force, changes the internal force distribution characteristics of the structure, reduces the internal force of the structural member, and is a dual lateral force resisting  structural system with good seismic performance, and can be applied  in high intensity areas and reinforcement and renovation projects.

Keywords:steel braced concrete  frame structure; RC frame structure; frame-shear wall structure; dual lateral force resisting system; damping ratio
