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. Diferent test methods are introduced in detail，and their advantages，disadvantages，andapplicabilities are analyzed systematically.The factors afecting the uniaxial compressive performance of rusted stirup confined concrete，the uniaxial compressive performance degradation model and the uniaxial stres-strain constitutive relationship model are summarized. The shortcomings and trends ofcurent 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 concreteunder repeated loads is very limited.Finally，the shortcomings and research trends of existing studies are discussed.
