Numerical study to investigate the behavior of reinforced concrete slabs with CFRP sheets
ABSTRACTThe current study implements nonlinear finite-element analysis using ANSYS15 software for the preparation of models to investigate the behavior of reinforced concrete slabs strengthened with carbon fiber-reinforced polymer (CFRP) sheets. A comparison between the results of ANSYS, experimental works, and equations of Egyptian Standing Code (ESC) was made for strengthened slabs with different sheet areas. Also, comparisons were carried out between strengthened slabs with equivalent applied areas that differ in distributions. The effects of the change of main reinforcement, compressive strength of concrete, slab thickness, and sheet thickness on strengthened slab behavior were investigated. The results of ANSYS are in good agreement with equation of ESC. The strengthening of examined slabs with CFRP sheets improves the flexural strength capacity. The distribution of CFRP sheets enhances the performance of studied slabs. The increase in compressive strength of concrete, slab thickness, and sheet thickness leads to increase in failure load magnitude of strengthened slabs. The increase in the main reinforcement increases the failure load to a certain limit. For the studied slabs, reinforcement bigger than 12 mm in diameter leads to a reduction in failure load.
