Analysis On The Seismic Behavior Of Buckling Restrained Steel Plate Shear Wall

Shear wall, as a component to resist lateral force, widely used in various kinds ofstructure system, has a long history. Reasonable to set the location of the shear wall,thereby to improve the seismic performance of the building structure. Shear wall hashigh bearing capacity, lateral stiffness big, the seismic performance of good advantages.Along with the development of The Times, people is higher and higher requirementsfor construction, we have more kinds of new type shear wall, Tsinghua university inChina put forward a new type of shear wall-buckling restrained steel plate shearwall(BR-SPSW), the shear wall is first put forward by professor Guo Yanlin andexperimental research. Prevent buckling of steel plate shear wall has the advantage thatcan significantly weaken the pull effect of embedded steel plates, the embedded plateof plane stress state, increase the ultimate bearing capacity of shear walls.This article main research object is the buckling restrained steel plate shearwall(BR-SPSW), using the nonlinear finite element method, through the ANSYS finiteelement software simulation analysis of the buckling, the seismic performance of steelplate shear wall under the action of earthquake. Key research prevent bucklingrestrained steel plate shear wall(BR-SPSW) applications in steel frame and shear wallseismic performance and overall in the shear wall structure seismic performanceinfluence.This paper first to prevent buckling restrained steel plate shear wall(BR-SPSW) inthe four layers of three cross steel frame system of the modal analysis and three andfour layer across steel frame steel plate shear wall structure system natural frequenciesof the contrast, a deeper understanding to this new structure system; Analysis threespans four layer steel frame buckling restrained steel plate shear wall structure,respectively, according to outside load, according to inertia force and seismiccalculation under the earthquake effect, structure in the X, Y, Z three directions of themaximum displacement, maximum stress analysis, contrast four layer three span steelplate shear wall steel frame structure system, put forward against the bucklingrestrained steel plate shear wall superiority, focus on analysis of the buckling restrainedsteel plate shear wall under the action of the three seismic calculation method for themaximum displacement and maximum stress and stress effect on the structure. Through a series of analysis, to prevent buckling restrained steel plate shear wallstructure system has carried on the research and exploration, the conclusion for thisnew type of shear wall structure system of further research and development to providecertain guiding significance and theoretical reference value.
