摘要：箍筋可显著提高混凝土构件延性，在弹塑性分析中，合理的箍筋约束混凝土本构模型可更真实地反映结构的动力响应。已有的部分抗震性能化相关标准和规程中，给出了建议的约束混凝土本构模型和相应的构件性能评价准则，但由于本构模型多样且评价准则存在差异，应用不同方法对结构弹塑性分析结果带来的影响尚不明确。基于目前工程中常用的Mander模型、Kent-Park模型和钱稼茹模型等约束混凝土本构，结合现有不同的性能评价方法展开了一系列研究。从工程应用角度，对比分析了不同本构模型的适用范围、骨架曲线差异和应用便捷性；基于某钢筋混凝土压弯试件和某钢筋混凝土框架结构，对比分析了不同模型对构件滞回性能和结构层间位移角等宏观弹塑性响应的影响，以及应用不同评价方法对构件性能评价结果的影响。结论可为工程项目在进行动力弹塑性分析时，如何选择和应用箍筋约束混凝土本构模型，以及了解现有不同性能评价方法的特点和差异，提供良好的参考。

Study on the application of stirrup-confined concrete constitutive models in elastic-plastic analysis
Abstract: Stirrups can significantly improve the ductility of concrete members. In the elastic-plastic analysis, a reasonable stirrup-confined concrete constitutive model can reflect the dynamic response of the structure more realistically. In some of the existing standards and regulations for seismic performance, constitutive models of confined concrete and corresponding evaluation criteria for member performance have been recommended. However, because of the variety of constitutive models and evaluation criteria, the impact of using different approaches on structural elastic-plastic analysis is not yet clear. Based on the Mander model, Kent-Park model, and Qian Jiaru model, which were widely used in engineering, a series of studies have been carried out in combination with different existing performance evaluation methods. From the perspective of engineering application, the scope of application, differences in skeleton curves and ease of application of different constitutive models were compared and analyzed. Based on a reinforced concrete beam-column specimen and a reinforced concrete frame structure, the effects of different models on the elasto-plastic response such as the hysteretic performance of the member and the displacement angle between the layers of the structure were compared and analyzed. Additionally, the effects of employing various evaluation criteria on the performance evaluation results of the member were examined. The conclusion can serve as a useful guide for choosing and using stirrup-confined concrete constitutive models for dynamic elastic-plastic analysis in engineering projects, as well as for comprehending the characteristics and differences among various performance evaluation techniques currently in use.
Keywords: confined concrete; constitutive model; elastic-plastic analysis; hysteretic behavior; performance evaluation
