Abstract

Abstract

Two standard wall panel units were tested under bending load to study the flexural behavior of light-gauge steel stud concrete composite wall panel (SC wall panel) and the stud spacing was considered as an experimental parameter. The experimental results showed that the failure of SC wall panels were mainly caused by the buckling of the stud and the bearing capacity of the SC wall panel was controlled by the serviceability limit state. Moreover, stud spacing had a great influence on the bearing capacity of the SC wall panels. Then, finite element models of SC wall panels were established with ABAQUS and a parameter analysis was conducted. The results showed that the flexural behavior of SC wall panels was mainly influenced by the thickness of the keel, the height of the web, the type of the thermal insulation material, the air layer and the spacing of the shear studs. The flexural capacity of the composite wall panels could be greatly improved when the air layer was cancelled. Besides, replacing the rock wool with foam concrete could effectively restrict the deformation of the stud and improve the flexural capacity and energy dissipation capacity of the SC wall panels.
