摘要：
To improve the seismic behavior and resilience of reinforced concrete structures, four specimens of shear walls reinforced by steel strands and steel bars with different axial compression ratios and boundary stirrups were designed. Through the low cycle revered lateral load tests of the shear walls, the crack propagation and failure pattern of the shear walls were studied. The effects of the axial compression ratio and boundary stirrup form on the hysteretic characteristics, deformation capacity, reinforcement stress, stiffness degradation, energy dissipation capacity and resilient performance (residual deformation, residual crack) of the specimens were discussed. The test results show that with the increase of the axial compression ratio, the lateral deformation capacity of the specimen decreases, the horizontal load at the same displacement angle increases, and the residual deformation increases to a certain extent. Compared with the specimens with circular boundary stirrups, the ultimate load and lateral deformation capacity of the specimens with composite stirrups are enhanced, and the residual deformation of the latter is slightly smaller at the same axial compression ratio. © 2020, Editorial Office of Journal of Building Structures.
