    摘要:

    锈蚀箍筋约束混凝土的单轴受压性能是对多龄期钢筋混凝土(RC)结构进行弹塑性分析与抗震性能研究的基础,准确研究其劣化规律,对于多龄期RC结构耐久性能评估、剩余抗震能力预测和数值模拟等具有重要作用。从试验方法、抗压强度和应力-应变本构关系等方面综述锈蚀箍筋约束混凝土单轴受压性能研究现状;详细介绍不同的试验方法,并系统分析其优缺点和适用性;归纳总结锈蚀箍筋约束混凝土单轴抗压性能的影响因素、退化模型和单轴应力-应变本构关系模型;分析当前锈蚀箍筋约束混凝土单轴受压性能研究中存在的不足及研究趋势。既有研究成果表明,现阶段关于重复荷载作用下锈蚀箍筋约束混凝土单轴应力-应变本构关系的研究十分有限。最后,对现有研究中存在的不足及研究趋势进行了讨论。

    Abstract:

    The uniaxial compression performance of rusted hoop-restrained concrete serves as the foundation for the elastoplastic analysis and seismic performance research of multi-age reinforced concrete (RC) structures. The precise study of its deterioration rule is of great importance for durability evaluation, residual seismic capability prediction and numerical simulation of multi-age RC structures. In this paper, the research status of uniaxial compression behavior of concrete restrained by rusted stirrup is reviewed from the aspects of test method, compressive strength and stress-strain constitutive relation. Different test methods are introduced in detail, and their advantages, disadvantages, and applicabilities are analyzed systematically. The factors affecting the uniaxial compressive performance of rusted stirrup confined concrete, the uniaxial compressive performance degradation model and the uniaxial stress-strain constitutive relationship model are summarized. The shortcomings and trends of current research on the uniaxial compression performance of concrete restrained by rusted stirrups are analyzed. A summary of existing research results shows that the current research on the uniaxial stress-strain constitutive relationship of rusted stirrup confined concrete under repeated loads is very limited. Finally, the shortcomings and research trends of existing studies are discussed.
