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.

Steel Reinforced Concrete

Nonlinear finite element analysis of abnormal exterior joints consist of Steel Reinforced Concrete column and Reinforced Concrete beam was performed using ABAQUS computation program, the joints failure mode and the skeleton curve were calculated. Comparison with experimental results to prove the reliability of finite element analysis. Then, the paper analyzed different parameters which affect the joints loading capacity, the results indicate that to a certain extent, the eccentricity of the upper and lower column sections and steel ratio both have important effects on the stiffness and ultimate loading capacity of the joints; with the increment of the ratio of axial compression, the joints ductility will be reduced.
