This study studied the flexural performance of HSC one-way reinforced concrete slab
reinforced with BFRP bars. The study incorporated experimental examination and Nonlinear 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.
