| Abstract: | Rehabilitation of RC members with high-strength wire mesh and polymer mortar is a new method of structural strengthening with the advantage of resistance to fire,corrosion and ageing.The finite element method(FEM) for evaluating the nonlinear analysis of the shear behavior of RC members strengthened with high-strength wire mesh and polymer mortar is presented in this paper.The analytical results show that FEM could effectively simulate the shear behavior of the repaired members with the proper numerical model.The analytical and experimental results indicate that the strengthening method is effective in increasing the shear stiffness,cracking load and ultimate capacity and validate the feasibility and advantage of the FEM analysis using ANSYS. |
| Keywords: | high-strength steel wire mesh polymer mortar FEM strengthening |
