This study studied the flexural performance of HSC one-way reinforced concrete slab reinforced with BFRP bars. The study incorporated experimental examination and Non-linear finite element study for seven BFRP concrete slabs had dimensions 700 × 1700 mm with a thickness 120 mm and 140 mm. The experimental test results showed that the ultimate flexural loads and behavior of concrete slabs reinforced with BFRP were improved compared with concrete slabs reinforced with steel reinforcement. Also, the tensile strength of BFRP bar is 2.5 times greater than the yield strength of steel reinforcement and 1.79 times greater than the tensile strength of bar. The structural behavior of the tested slabs was validated with the theoretical developing a finite element models utilize software ANSYS 2019-R1 program. Good agreement between the numerical and experimental results in first cracking loads, load-carrying capacity, crack pattern and deflections were found. The agreement between the experimental load carrying capacity and NLFE ones is about 89.0 % with coefficient of variance equals 0.001 and standard deviation of 0.03. The finite element analysis gave suitable guessing for the structural performance of the nonlinear BFRP concrete slab. |
