Shear force demand on headed stud for the design of composite steel plate shear wall

Composite steel plate shear wall (C-SPW) consisting of steel plate with reinforced concrete encasement on one or both sides of the steel plate using headed studs is an effective lateral load resisting system. Previous researches focus mainly on its seismic behavior, while few researchers pay attention to the shear force demand on headed stud, which is an important issue in the design of C-SPW. In this paper, an investigation on the shear force demand on headed stud for the design of C-SPW is carried out by finite element analysis. A novel finite element model incorporating an effective simulation of boundary frame as well as reasonable interaction behaviors of elements is established using ABAQUS and validated in comparison with available tests. The responses of structural elements in C-SPW under monotonic lateral load are investigated. The effects of headed stud diameter, infill steel plate thickness, concrete panel thickness, number of headed studs as well as aspect ratio of shear wall on the maximum stud shear force are analyzed. Based on the analysis results, an available formula for the demand on stud shear force in the design of C-SPW is proposed.
