In order to study the mechanical behavior on concrete continuous beams strengthened with CFRP sheets, three two-span continuous beams strengthened with CFRP sheets in the control section at each span were fabricated and tested with two-point loading type. The test data such as load, crack distribution and deformation were obtained in different stages. Based on the test data, the finite element analysis on the continuous beams strengthened with CFRP sheets was carried out by ANSYS software. The variation of steel stress and deflection of control section in the intermediate support and the bearing capacity in different stages were obtained, moreover, the results show that the ultimate strength of continuous beams strengthened with CFRP sheets has not improved largely in elastic state while increased significantly in plastic state, and the continuous beams displayed obviously internal force redistribution.
