Abstract:
In order to study the influence of different coaxial pressure ratio on the hysteresis performance of the assembled regenerated concrete shear wall, the quasi-static simulation experiment and systematic analysis of the shear wall are carried out by using the finite element software in this paper. The results show that the bearing capacity of the shear walls increases and the ductility decreases with the increase of the axial compression ratio.The axial compression ratio increases by 0.1, the yield load increases by 13.2%, the peak load increases by 15.3%, and the ductility coefficient decreases by 10%.With the decrease of axial compression ratio, the initial stiffness of shear walls decreases and the speed of stiffness degradation is faster before the failure stage.When designed the assembled recycled concrete shear wall structure in practical engineering, the axial compression ratio should be strictly controlled, and the light floor should be chosen as far as possible to reduce the axial compression ratio of the composite shear wall. The axial compression ratio should not exceed 0.4. The structure can be applied to small high-rise buildings through reasonable design.
