摘要：

In order to improve the seismic performance of high-strength concrete shear walls, the high-strength rectangular spiral reinforcements (HRSRs) are applied to the constrained edge members and wall body of high-strength concrete shear wall. Through the seismic performance investigations of 10 high-strength concrete shear walls confined with HRSR, and considering the strong constraint of HRSR, the bending moment curvature calculation method of high-strength concrete shear walls confined with HRSR is proposed corresponding to the cracking, yielding, peak and ultimate states. The study shows that the bending moment curvature formula of the bending member can describe the load-deformation relation of the shear wall more accurately, and the calculated values are in good agreement with the experimental values. Compared with the form of common stirrup, the continuous closed HRSR can significantly improve the sectional bearing capacity and deformation capacity of high-strength concrete shear walls.
