【 摘 要 】

To study the seismic behavior and post-earthquake repairability of coupled shear wall with concrete filled steel tube (CFST) frame and concealed partitioned steel plates (SPs), three 1/5 scaled coupled shear wall specimens were designed with different type of CFST column or core structure. Low-cycle reversed loading was adopted in the test. The test contained two stages. Load-carrying capacity, energy dissipation, ductility, stiffness and failure characteristic of the specimens were compared in pre-repair stages and post-repair stages. The conclusions are drawn that the core structure shows a good ductile yielding mechanism. The cross-section type of frame has an obvious effect on the seismic behavior of shear wall. After damage and strengthening, the new coupled shear wall still has enough seismic capacity and good energy dissipation capacity, and it is easy to be repaired after earthquake. Finite element analysis software ABAQUS has been used to simulate the behavior of coupled shear wall. Ultimate strength is obtained with the vibration of thickness of SPs.
