Cyclic Test for Framed Steel Plate Walls with Various Infill Plate Details

Abstract eng:
The framed steel plate wall has been used in U.S, Canada, and Japan, primarily as an earthquake resisting system. However, in order to design the steel plate wall system effectively, it was needed to verify the structural capacity of steel plate walls with various infill plate details that can be applied in practical affairs. In the present study, experimental studies were performed to investigate the variations of the structural capacity of steel plate walls with various infill plate details. The major parameters for the test specimens were the location and length of weld-connection, coupling wall, and the connection details between the moment frame and infill plates, such as, weld- and bolt-connections. A concentrically braced frame (CBF) and a moment-resisting frame (MRF) were also tested for comparison. Regardless of the infill plate details, the steel plate wall specimens exhibited excellent initial stiffness, strength, and energy dissipation capacity. However, the wall with bolt-connected infill plates showed slightly low deformation capacity. This result indicates that for architectural reasons and cost-saving, various wall details can be used in practice without a significant decrease in the structural capacity of the steel plate walls.
