Study On Seismic Performance Of H Shaped Steel Frame-Corrugated Steel Shear Wall

The corrugated steel shear wall has the advantages of high lateral stiffness,high bearing capacity and energy dissipation.The corrugated steel shear wall studied in here is composed of H frame and embedded corrugated steel plate.The flat steel was bent into sinusoidal corrugated steel plate,which make it have larger out-of-plane stiffness.The corrugated steel plate can be divided into two kinds,the vertical wave and horizontal wave according to the different wave direction.In this paper,the seismic performance of H-shaped steel-corrugated steel shear wall is studied by means of experimental research and finite element numerical analysis.The main contents include:(1)The cycle loading test of H-shaped steel frame-corrugated steel shear wall and the flat steel shear wall were carried out,and which seismic performance was studied respectively.The experimental results show that the corrugated steel plate has a large anti-lateral stiffness,higher bearing capacity,stable hysteresis performance and good energy dissipation capacity.H shape steel column of corrugated steel shear wall,have a major influence on the performance of the corrugated steel plate shear wall.H shape steel frame should have enough bending stiffness,and provide the embedded corrugated steel plate strong constraint action,to give full play to the bearing performance of the embedded corrugated steel.(2)The test model simulation analysis was carried out by the ABAQUS 6.13 version finite element soft ware.The finite element simulation results was compared with the test results and better fitting,which exhibit that the corrugated steel plate shear wall can be calculated by the finite element software,also was verified feasibility to replace and expand the testing method.(3)By using the finite element software,the hysteretic properties of the corrugated steel plate shear wall,stress and strain and surface deformation and stress field are analyzed,loading carry and failure mechanism were revealed.The results show that the vertical corrugated steel shear wall can effectively bear the vertical load,and the horizontal corrugated steel shear wall have better shearing carry ability.(4)The influence of axial compression ratio,high thickness ratio and high width ratio of corrugated steel plate shear wall are analyzed.Results show that the axial compression ratio have smaller influence on the initial stiffness,bearing capacity,energy dissipation capacity of corrugated steel plate shear wall structure.The initial stiffness,bearing capacity and energy dissipation capacity of corrugated steel plate shear wall can be effectively increased by decreasing the high thickness ratio or increasing the high width ratio.
