Abstract

Carbon fiber-reinforced polymer (CFRP) rebars can promote the life-cycle performance of concrete structures due to their high strength and corrosion resistance. However, the application of CFRP rebars into concrete structures is limited because their linear-elastic behavior deviates from the traditional ductile seismic design. To investigate the seismic performance of CFRP-reinforced concrete (CFRP-RC) columns, four CFRP-RC columns, one RC column, and one CFRP/steel hybrid RC column were tested under quasi-static loads, with parameters including longitudinal reinforcement ratio, stirrup spacing, and axial compression ratio. Crack patterns, bearing capacity, residual deformation, and energy dissipation were investigated. Results indicated that the RC column was controlled by rebar buckling and core concrete crushing, while the CFRP-RC columns were controlled by the brittle fracture of the CFRP rebars, which were easily sheared due to the lateral resistance of stirrups against the compressive CFRP rebars. CFRP-RC columns exhibited high strength with a drift larger than 5%, small residual drift, and weak energy dissipation, exhibiting distinct advantages and disadvantages: “strong bearing capacity and low damage” but “low ductility and brittle failure”. The test formed a key dataset to provide a basis for seismic design and application of CFRP-RC structures.
