ABSTRACT

Three T-shaped concrete walls built with HRB 600 MPa reinforcement were tested under cyclic loading, and research parameters included axial load ratio and lateral loading direction. As part of the study, the method to obtain the yield strength and deformation was proposed. Test results show that compared to the specimen loaded along the web length direction, the wall loaded at 45° direction has smaller strength, initial stiffness, energy dissipation, and larger drift ratio capacity. The tension strength of HRB 600MPa reinforcement can be fully used in T-shaped walls. The method for yield strength and deformation has reasonable calculation accuracy.

摘要

采用HRB 600 MPa钢筋建造的三堵T型混凝土墙在循环荷载下进行了试验，研究参数包括轴向荷载比和横向荷载方向。作为研究的一部分，提出了获得屈服强度和变形的方法。试验结果表明，与沿腹板长度方向加载的试件相比，45°方向加载的墙体具有较小的强度、初始刚度、耗能和较大的漂移比容量。HRB 600MPa钢筋的抗拉强度可充分用于T型墙。屈服强度和变形的方法具有合理的计算精度。
