Seismic Behavior Of Three Typical Steel Plate Shear Walls

Frame-core wall structures are popular systems for high-rise buildings,in which shear walls are key elements to resist lateral loading.Steel plate shear walls(SPSWs)are a new kind of lateral resisting elements with high strength and stiffness,as well as ductility and energy dissipation capacity.Based on the finite element analysis method,this paper compares and analyzes the seismic behavior of three kinds of thin steel plate shear wall,the non stiffened steel plate shear wall,the stiffened steel plate shear wall and the buckling restrained steel plate shear wall.Firstly,using finite element software ABAQUS to establish the finite element of three kinds of thin steel plate shear wall model,analyze the back loading lag,will test results and related results in the literature are compared to verify the correctness and reliability of the finite element analysis method.Then a unified component geometry and section size,set up three kinds of thin steel plate shear wall model of single span,influence analysis of edge frame column stiffness and embedded steel plate width to thickness ratio and span to height ratio of steel plate shear wall stiffness,strength,ductility and energy dissipation capacity.On this basis,established the finite element of steel frame steel plate shear wall structure model,pushover analysis and time history analysis of the thin steel plate shear wall to compare the different effects on the structure of the system,a experiment of three kinds of steel plate shear wall with three blocks of the same size,comparison and analysis of results further comparison and verification of the front.Analysis results show that the stiffness of VBE has significant effection on SPSW,but less effeciton on SSPSW and BR-SPSW.The energy dissipation capacity of SSPSW and BR-SPSW is better than SPSW.Steel frame-SPSW structure has multiple seismic resistance members.The failure procedure of this structure system is infilled steel plate yield first,and then horizontal boundary elements yield,finally the frame beams yield.The results of this dissertation can provide guidance to engineering.
