Numerical investigation of Slabs

This study investigated the flexural performance of high-strength concrete (HSC) one-way reinforced concrete slabs reinforced with Basalt Fiber Reinforced Polymer (BFRP) bars. Both experimental testing and nonlinear finite element analysis (NLFEA) were conducted on seven BFRP-reinforced concrete slabs with dimensions of 700 × 1700 mm and thicknesses of 120 mm and 140 mm. The experimental results indicated that the ultimate flexural capacity and overall behavior of BFRP-reinforced slabs were improved compared to those with conventional steel reinforcement. The tensile strength of the BFRP bars was found to be approximately 2.5 times greater than the yield strength of steel reinforcement, and 1.79 times higher than the tensile strength of conventional bars. Structural performance observed in the experimental study was validated through finite element modeling using ANSYS. The correlation between experimental and numerical results showed a high level of agreement, with an average match of 89%, a coefficient of variance of 0.001, and a standard deviation of 0.03. The finite element analysis proved effective in predicting the nonlinear structural response of BFRP- reinforced concrete slabs.
