Abstract

In order to study the mechanical performance on concrete columns strengthened with prestressed CFRP sheets, three groups of twelve concrete columns were made, according to the reinforcement ratio and tensile stress of CFRP sheets. Then the axial compression test under static load was completed and the experimental data was obtained. Moreover, the collapse state, ultimate bearing capacity and the steel and concrete strain analysis were studied. The results show that the prestressed CFRP sheets could put off the appearance and development of initial cracks, limit the lateral deformation of the concrete, improve the ultimate strength and compressive strain of the concrete. At the same time the longitudinal reinforcement give full play to the performance of plastic deformation. The columns strengthened with prestressed CFRP sheets were simulated by ANSYS software, the result shows that the test and the analysis value are in good agreement.
