The article makes a simulation on the external CFRP prestressed reinforced concrete continuous beams with ANSYS, the beams which had made analysis by Kiang Hwee Tan and Robert A. Tjandra. There is a little difference between the results of simulation and experimental results. It shows the reliability of simulation on concrete continuous beams with ANSYS. Then it makes a finite element analysis about parameters of the bending properties of continuous beams. It could provide relevant information about bending performance of concrete continuous beams with external CFRP prestressed tendons.
