摘要：

In order to explore the feasibility of using carbon fiber reinforced plastics （CFRP） in the plastic hinge to control the failure mode and further improve the seismic performance of concrete shear wall reinforced by steel strand and steel bar，two specimens of concrete shear wall reinforced by steel strand and steel bar were made. The seismic and resilient performance of concrete shear wall reinforced by steel strand and steel bar and confined by CFRP in plastic hinge was studied by quasi-static loading test. The results show that the plastic hinge of concrete shear walls reinforced by steel strand and steel bar and confined by CFRP can effectively improve both bearing capacity and lateral deformation capacity，and the effect of improving its bearing capacity is better under high axial compression ratio，the hysteretic loops of the specimens confined by CFRP are fuller，and the energy dissipation capacity is improved to a certain extent，but it has no obvious effect on its residual drift. © 2023 Science Press.
