Analysis of Seismic Performance of High-strength Steel Bar Concrete Short-leg Shear Wall
In this paper,three kinds of short-limb shear walls were prepared by orthogonal test method.The hysteretic characteristics,skele-ton curve,stiffness degradation trend,energy dissipation capacity and self-resetting ability of the short-limb shear walls were tested by low-cycle repeated loading test.The seismic performance of high-strength steel-bar concrete short-limb shear walls was comprehensively analyzed.The results show that high-strength steel rod can significantly improve the load-carrying capacity and self-resetting capacity of short-leg shear wall.When the displacement Angle is 3.5%,the ultimate bearing capacity of high-strength steel rod concrete short-leg shear wall is in-creased by 67.03%,and the residual deformation is reduced by 67.35%,and it is further increased under the action of high axial compression ratio.The energy dissipation of ordinary concrete short-leg shear walls is higher,and the axial compression ratio has little influence on the e-quivalent viscous damping coefficient of the specimens.
