| Reinforced concrete shear wall and core tube is a main lateral resistance member of horizontal seismic load and wind load in tall and super high-rise buildings.In order to ensure this kind of complex structure with good seismic performance,especially the reinforcing area at the bottom several layers of the structures,massive reinforced concrete shear walls or steel concrete composite shear wall are usually used,which can resist horizontal load and ensure the ductility of the structure performance.Inspired by the the large stiffness out of plane of corrugated steel plate,and from the point of view of taking the advantages of both steel and concrete,Corrugated steel plate shear walls and corrugated steel concrete composite shear walls are proposed.Corrugated steel plate shear wall is composed of surrounding steel frame and embedded corrugated steel.The steel frame can be shape steel,Embedded corrugated steel plate is bended by a flat plate in a certain interval and bending angle,according to the wave direction it is divided by vertical and horizontal placement type.Corrugated steel concrete composite shear wall is that the corrugated steel plate shear wall are ecased by the concrete outside,through the design of a certain seismic detailing measures,such as place the shear stud,binding rebar.,distributed reinforcement,etc,which inorder to ensure the effective bond anchorage of steel and concrete,make the steel plate and concrete deformation and energy dissipation,give full play to the combination of the composite effect.Based on background of the engineering practice and the present study focus on the flat steel plate shear wall and flat steel concrete composite shear wall,in order to bring the corrugated steel's advantages of out-of-plane stiffness to improve the lateral stiffness and ductility of shear wall.Design and make a flat steel plate shear wall specimen and 2 corrugated steel plate shear wall specimens,then put them into the concrete,which becoming a flat steel concrete composite shear wall specimen and 2 corrugated steel concrete composite shear wall specimens.Based on the quasi-static testing,the influence of different modes of steel plate arrangement and outer wrapped concrete are researched and analyzed,which will influence the lateral resistance behavior of steel plate shear wall and Steel concrete composite shear wall.The damage phenomenon of the test specimens,bearing capacity,ductility,strength,stiffness and energy dissipation capacity and so on were carried on the comparison and analyzed.The destruction of the steel plate shear wall form is usually due to instability of the outer frame.The bearing capacity,stiffness,ductility and energy dissipation of Composite shear wall will increase several times than the whole steel steel one under the influence of the constraint of concrete.Composite shear wall specimens are eventually damaged by the the bottom corner of the wall concrete crush and the yield flange of the exposed H-shape steel,so it is essential to design effective confined boundary elements.Finite element numerical simulation are carried on of the horizontal and vertical corrugated steel plate shear wall specimens,the finite element analysis is verified by comparring with the test failure features and hysteresis curves.In order to expand analysis the result of the test,using the ABAQUS finite element analysis software validating the corrugated steel plate shear wall specimen under reciprocating load role.The Hysteresis curves and experimental validations are obtained,related suggestions of designing and construction measures are put forward for the corrugated steel concrete composite shear wall.Numerical simulation analysis of using square steel tube as the boundary members of corrugated steel plate shear wall arecarried out.Seismic performance of horizontal and vertical corrugated steel plate shear wall is analyzed.Related Suggestions of the design and application of corrugated steel plate shear wall are put forward based on the test damage phenomenon and numerical simulation analysis results... |
