摘要:

A composite shear wall with concrete filled steel tube (CFST) boundary columns and embedded steel plates was proposed. The test shows it has good seismic behavior. In order to investigate its stress characteristic, the plane cross-section assumption was introduced based on the test study. The simplified calculation model for the normal section flexural load-bearing capacity was put forward. The formulae of stripe method were given and the corresponding calculation program was complied. The effect of the thickness of steel tube, thickness of the embedded steel plate and the concrete strength on the flexural load-bearing capacity was discussed. The calculated results are in good agreement with the test results. Results show that: the flexural load-bearing capacity is improved greatly with the increasing of the thickness of steel tube; the load-bearing capacity is improved with the increasing of the thickness of steel plate, but it has lower efficiency than increasing the thickness of steel tube; the flexural load-bearing capacity is improved marginally with the increasing of concrete strength, but the increasing amplitude decreases with the increasing of steel tube thickness; the parameters, such as the thickness of steel tube, thickness of embedded steel plate, the thickness of wall and concrete strength, should be set optimally so as to give full play to the seismic efficiency of composite shear wall.
