【Abstract】 Fiber reinforced polymer was increasingly interested in civil engineering due to its high performance such as light weight, high strength, good resistance to corrosion and fatigue, and thermal stability. In recent years FRP materials was extensively applied to the rehabilitation and retrofit of the multiple types of existing structure, even applied to the construction of new structures. A stateoftheart of FRPconfined concrete column was reviewed from the following aspects including the stressstrain relationship of confined concrete, the conclusions obtained through structural tests and the specifications in national and foreign corresponding design code and guidelines. Several key problems in the future research were put forward.更多还原
