Out-plane interaction behavior of partially buckling-restrained steel plate shear walls
Abstract Partially buckling-restrained steel plate shear wall (PBRSPSW) mainly involves a steel plate partially restrained by out-plane restraining members, which is convenient to be transported and installed. The energy dissipation ability of PBRSPSW can be adjusted by changing the number of the restraining members. This paper focuses on the interaction behavior between steel plate and restraining members in PBRSPSW. The buckling and out-plane interaction behavior of PBRSPSW are studied by the simplified analytic method. The out-plane interaction force acting on the partially buckling restraining member results from the tension action and extrusion effect of the steel plate. Furthermore, a simplified continuous trusses model considering the fully developed buckling mode of the steel plate is developed to simulate the out-plane interaction behavior in PBRSPSW. Based on the internal force analysis of the continuous trusses model, an out-plane interaction force equation of PBRSPSWs is derived. Additionally, experimental studies were carried out to investigate the out-plane interaction behavior of PBRSPSW. The test results indicated that the out-plane interaction force of the PBRSPSW rises with the decline of the unstiffened zone’s height-to-thickness ratio. The out-plane force at the corner and bottom regions are higher than that of other regions. Considering the influence of the plastic buckling of steel plate, the theoretical equation for calculating the out-plane interaction forces of PBRSPSWs is modified and verified with the test results.
Highlights Simplified model of partially buckling-restrained steel plate shear wall (PBRSPSW) is developed. Theoretical equation used to calculate out-plane interaction force of PBRSPSW is derived. Interaction force between steel plate and restraining member in PBRSPSW is. Distribution of out-plane interaction force between steel plate and restraining members is analyzed.
