| Abstract: | This paper presents an experimental and finite element method (FEM) investigation for evaluating the load deformation process of reinforced concrete two-way slabs strengthened with GFRP composites. The deformation and the variation of GFRP strain along with load were studied, and the mechanism of RC two-way slabs strengthened with GFRP strips was analyzed based on the numerical results. Compared with test results, the FEM results can effectively simulate the flexural behavior of two-way slabs strengthened with GFRP strips with the proper numerical model. The analytical and experimental results also indicate that the GFRP strips were effective in appreciably increasing the flexural stiffness, cracking load and ultimate capacity of the repaired slabs. |
