Nonlinear Model on Torsional Behaviors of CFRP Strengthened Reinforced Concrete Beams
In this paper, a reasonable three dimensional finite element beam model was developed to predict the mechanical behaviors of carbon fiber reinforced polymer (CFRP) strengthened RC box beam under combined bending, shear and torque. The comparison of calculated results with the experiment results of torque-twist relationship, the strain developments in steels and CFRP strips and the force of non-linear string element indicates that the finite element method presented in this study can simulate the behavior of beams well.
