Bearing Mechanism Study Of Sinusoidal Corrugated Steel Plate Shear Walls

In this paper,based on the Steel frame-steel plate shear wall,through comparing the differences in bearing between it and Corrugated webs,a new kind of structure type was proposed,the Steel frame—Sinusoidal corrugated steel plate shear walls structure.In this structure type,by changing Stiffness in two directions,Corrugated steel plate limited Steel plate’s Buckling Outside the surface,then improved the Anti-side performance of the new structure.In order to research the new structure’s Anti-side performance comprehensively,this paper have done the following works:(1)Introduced the steel frame-corrugated steel plate shear wall structure.And classified them according to the direction of the corrugation,the connection of different ways.And the junction structure of frame beam,column connection,corrugated steel plate and frame is briefly described.(2)Built the establishment of different types of steel frame-corrugated steel plate shear wall structure model respectively.And the static and elastic puffing analysis of each model was carried out.Analysis of different types of corrugated steel plate shear wall structure of the lateral bearing capacity of the size,stress and out-of-plane deformation development and other performance indicators are finished.(3)On the basis of the above study,the hysteretic behavior of four types of corrugated steel plate wall structures with high bearing capacity is studied under low cyclic loading.Analyzed the anti-lateral ultimate bearing capacity,stress and out-ofplane deformation of various corrugated steel slabs under low cyclic reciprocating load.Compared it with the static elastic-plastic push-over analysis data.(4)Analyzed the steel frame-corrugated steel plate shear wall,researched the effects of corrugated steel plate thickness tw,ripple wavelength L,ripple peak a,aspect ratio of corrugated steel plate ? and other factors on the anti-side performance.The study shows that,under the action of static push-down analysis,Corrugated steel plate with reasonable steel frame-corrugated steel plate shear wall structure has a high anti-side bearing capacity and good ductility.Under low cyclic loading,it has good hysteresis performance and bearing capacity stability.In general,Steel frame-corrugated steel plate shear wall is a good structure with anti-side performance.
