This paper presents an investigation on the cyclic behavior and design aspects of a hybrid self-centering wall (SW), in terms of the wall’s axial stress and post-tensioning tendons’ prestressing ratios. These key parameters are examined extensively within the context of both force and displacement-based design approaches. Finite element models of SWs are developed and verified against experimental results available from the literature. The numerical model is used to perform a parametric study where the wall’s behavior, including cyclic response, damage severity and pattern, energy dissipation, stiffness degradation, period shift, and residual drift are widely discussed in the context of the aforementioned design approaches. Numerical results indicate that an increase in the axial stress ratio intensifies the extent and severity of the wall’s damage, lateral capacity, residual drift, energy dissipation, and structural seismic demand. Additionally, it is shown that by increasing the tendons’ prestressing ratio, the structural seismic demand is increased, while the wall’s damage, residual drift, and energy dissipation capacity are decreased. Based on this study, the wall’s axial stress ratio and the tendons’ prestressing ratio should be limited to a range of 0.075–0.115 and less than 0.75, respectively, to meet the basic objective performance. Higher objective performance criteria could be maintained with using external energy dissipaters, and adopting a suitable design approach.

本文针对混合自定心墙（SW）的循环特性和设计方面进行了研究，涉及墙的轴向应力和后张预应力筋的预应力比。这些关键参数在基于力和位移的设计方法的范围内进行了广泛的检查。SW的有限元模型已开发并针对文献中的实验结果进行了验证。数值模型用于进行参数研究，其中在上述设计方法的背景下广泛讨论了墙体的行为，包括循环响应，损伤严重性和样式，能量耗散，刚度退化，周期位移和残余漂移。数值结果表明，轴向应力比的增加会加剧墙体破坏，侧向承载力，残余漂移，能量耗散和结构地震需求的程度和严重性。此外，还表明，通过增加钢筋束的预应力比，可以增加结构抗震需求，同时减少墙体的破坏，残余位移和能量耗散能力。根据这项研究，墙的轴向应力比和钢筋束的预应力比应分别限制在0.075-0.115和小于0.75的范围内，以满足基本的目标性能。通过使用外部耗能器并采用适当的设计方法，可以维持更高的客观性能标准。此外，还表明，通过增加钢筋束的预应力比，可以增加结构抗震需求，同时减少墙体的破坏，残余位移和能量耗散能力。根据这项研究，墙的轴向应力比和钢筋束的预应力比应分别限制在0.075-0.115和小于0.75的范围内，以满足基本的目标性能。通过使用外部耗能器并采用适当的设计方法，可以维持更高的客观性能标准。此外，还表明，通过增加钢筋束的预应力比，可以增加结构抗震需求，同时减少墙体的破坏，残余位移和能量耗散能力。根据这项研究，墙的轴向应力比和钢筋束的预应力比应分别限制在0.075-0.115和小于0.75的范围内，以满足基本的目标性能。通过使用外部耗能器并采用适当的设计方法，可以维持更高的客观性能标准。为了满足基本的目标性能，墙的轴向应力比和钢筋束的预应力比应分别限制在0.075-0.115和小于0.75的范围内。通过使用外部耗能器并采用适当的设计方法，可以维持更高的客观性能标准。为了满足基本的目标性能，墙的轴向应力比和钢筋束的预应力比应分别限制在0.075-0.115和小于0.75的范围内。通过使用外部耗能器并采用适当的设计方法，可以维持更高的客观性能标准。
