Shear Force Demand On Headed Stud For The Design Of Different Aspect Ratio C-SPW With Concrete Panel On Two Side Of Steel Plate

Composite steel plate shear wall(C-SPW)is an effective lateral load resisting system which has higher lateral stiffness and shear resistance than concrete shear wall and steel plate shear wall.Reinforced concrete panel provides effective lateral restraint to prevent the prematurely buckling of steel plate.In the ductility design of C-SPW,steel plate should have certain plastic deformation and energy dissipation capacity after reaching its shear yield.To date,the design guidelines for C-SPW have not been completed yet,resulting in the limitation to the application of C-SPW.In this paper,the shear force demand on headed stud in the C-SPW with reinforced concrete encasement on both sides of the steel plate is studied.28 specimens are designed and the C-SPW finite element model is established using ABAQUS software.The responses of structural elements in C-SPW under monotonic lateral load are investigated,the interactive action between different structural components and the performances of the infill steel plate,concrete panel and headed stud are investigated deeply.The effects of depth-width ratio of wall,steel plate thickness,concrete plate thickness and stud diameter on shear bearing capacity of C-SPW and shear force of headed studs are analyzed.Based on the results from finite element simulation,a formula for the demand on stud shear force in the design of C-SPW is proposed.
