Research on hysteretic behaviour of high-strength concrete shear wall plate for steel tube in building construction

摘要

For the problem of insufficient analysis of the hysteretic behaviour of the traditional concrete shear wall, the research method of hysteretic behaviour of high-strength concrete shear wall for steel tube in building construction is proposed in paper. Based on the OpenSee platform, the displacement of the base was recorded by the displacement metre installed on the base, and the load displacement curve is plotted, and the shear bearing capacity of the model was analysed. The failure modes, axial compression ratio and concrete strength parameters of the specimens were studied to obtain the following conclusions. Higher the axial compression ratio and the wall shaft pressure, the higher the load capacity of the specimen. By comparing the hysteretic behaviour of different steel tube high strength concrete shear strength specimens, this paper analyses the performance of steel tube high strength concrete shear wall panels, which provides data and reference for future construction.
