Abstract: | The seismic performance of composite steel plate shear walls (CSPSWs) that consist of a steel plate shear wall (SPSW) with
reinforced concrete (RC) panels attached to one or both sides by means of bolts or connectors is experimentally studied. The
shear wall is connected to the frame beams but not to the columns. This arrangement restrains the possible out-of-plane buckling
of the thin-walled steel plate, thus significantly increasing the bearing capacity and ductility of the overall wall, and
prevents the premature overall or local buckling failure of the frame columns. From a practical viewpoint, these solutions
can provide open space in a floor as this type of composite shear walls with a relatively small aspect ratio can be placed
parallel along a bay. In this study, four CSPSWs and one SPSW were tested and the results showed that both CSPSWs and SPSW
possessed good ductility. For SPSW alone, the buckling appeared and resulted in a decrease of bearing capacity and energy
dissipation capacity. In addition, welding stiffeners at corners were shown to be an effective way to increase the energy
dissipation capacity of CSPSWs. |
