［摘要］通過鋼支撐-混凝土框架結(jié)構(gòu)體系、RC框架結(jié)構(gòu)體系和框架-剪力墻結(jié)構(gòu)體系的對比分析，結(jié)果表明，鋼支撐-混凝土框架結(jié)構(gòu)提高了結(jié)構(gòu)側(cè)移剛度，降低了結(jié)構(gòu)自振周期，減小了結(jié)構(gòu)側(cè)移和層間位移角；鋼支撐分擔(dān)了部分樓層剪力，改變了結(jié)構(gòu)的內(nèi)力分布特點，降低了結(jié)構(gòu)構(gòu)件的內(nèi)力，為雙重抗側(cè)力結(jié)構(gòu)體系，具有良好的抗震性能，可應(yīng)用于高烈度地區(qū)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
