The concrete columns confined by high-strength stirrups exhibited higher bearing capacity and better deformation ability. Based on the test results of concrete columns confined by high-strength stirrups under lateral cyclic loading, it is found that stirrup yield strength could not be used directly in calculating bearing capacity, because the high-strength stirrup could not yield at the peak point. Moreover, according to the seismic performance of a total of 49 sets of confined concrete columns from this paper and other 5 research papers, an easy-to-use model of skeleton curve is proposed by using a set of empirical equations to calculate the characteristic points of skeleton curve. Furthermore, based on the proposed model of skeleton curve, hysteretic rules are developed for the unloading and reloading stages by providing calculating formula of unloading stiffness and ignoring the effect of strength degradation. Finally, the proposed model of skeleton curve and hysteretic rules are verified and evaluated by comparing the calculated curves and experimental curves.

高强箍筋约束的混凝土柱表现出更高的承载力和更好的变形能力。结合高强箍筋约束混凝土柱在横向循环荷载作用下的试验结果发现，由于高强箍筋在峰值点不能屈服，不能直接用箍筋屈服强度计算承载力。此外，根据本文和其他5篇研究论文中总共49组约束混凝土柱的抗震性能，通过使用一组经验方程来计算特征点，提出了一种易于使用的骨架曲线模型骨架曲线。此外，基于所提出的骨架曲线模型，通过提供卸载刚度的计算公式并忽略强度退化的影响，为卸载和重新加载阶段制定了滞回规则。最后，通过对比计算曲线和实验曲线，对提出的骨架曲线模型和滞回规律进行了验证和评价。
