rc coupling
1.Based on the continuous damage theory, considering the shear effect, the high-order shearing, flexural and in-plane deformation coupling model is built; through the nonlinear FEM analysis of RC beams strengthened with FRP, the damage theory and damage course is researched; Compared with experiment results, it shows that the model is effective; The FEM analysis software is prepared to provide simple and effective method for the engineering application; using the soft the FRP strengthened beams before and after damage is modeled so as to provide the theory base for engineering application.
