Study On Seismic Behavior Of Steel Frame Structure With Steel Plate Brace Precasted In Shear Wall

Along with the development of the high-rise building, the level force is very important in designing the buildings, and the steel plate brace precasted in shear wall is a good type of lateral force resisting system. This kind of structure system will be used widely in the high-rise buildings because it holds the merits such as better earthquake-resistance performance,low cost,fast construction speed and so on. Because both of the experiment study and the theory research of this structure are few at present in our country, SAP2000 is applied to analyze the working behaviors of this system to ensure the safety of the structure.In this paper,the characteristics and performance of the structure, the steel plate brace precasted in shear wall,is studied. The model is established to analyze the linear elastic behavior of the system. For the restriction effect of concrete versus steel plate brace,its stability and stiffness can be enhanced greatly. By the study in the variety of the geometrical parameter of the structure model,we can get the influence of working performance of the structure by it and the interrelated conclusion of the buckling behavior, stiffness improving,and working stability of the steel plate brace precasted in shear wall,what can be used in the structure designing in the future.Owing to the superior work function of the steel plate brace precasted in shear wall system, the main structure of a real engineering project is analyzed in this paper. SAP2000 is applied to establish an appropriate calculation model and analyze the dynamic performance, spectrum response and time-history response of the structure, which use the steel plate brace precasted in shear wall system. And at last,the response characteristic of the buildings under earthquake is concluded. Contrasting with the other lateral force resisting systems, the excellent work function of this new system can be summarized by study. At last, it is a conclusion that this new system is a promising lateral force resisting system and it will be applied widely in the future actual engineering project.
