Abstract:The quasi-static experiment was conducted on 2 pieces of prefabricated hollow shear walls with different axial compression ratios. The failure process of the wall was described, and the seismic performance such as the failure characteristics, hysteresis characteristics and energy dissipation capacity of the walls were analyzed. The results show that the prefabricated hollow shear wall suffers from bending and shear failures. With the increase of the axial compression ratio, the bearing capacity of the wall is increased, the ductility is improved, the energy dissipation capacity is improved and the rigidity degradation is accelerated. The seismic performance of the prefabricated hollow shear wall is good, and it has large security reserves when it is applied to the structure with three layers or less under low axial pressure ratio. Finally, the correction coefficient of elastic stiffness calculation formula of the prefabricated hollow shear wall was given in combination with the experimental results and the related literatures.
Keywords:prefabricated hollow shear wall; seismic performance; hysteretic characteristic; pseudo-static experiment; stiffness formula
