Abstract
The precept of replacement of the steel reinforcement with glass fiber-reinforced
polymer (GFRP) bars was investigated before overcoming the issue of steel
reinforcement corrosion in concrete structures exposed to aggressive corrosions.
Although, lower modulus of elasticity of GFRP and their ductile characteristic
results in large deflection and wide cracks in FRP-reinforced concrete members.
This paper investigates the experimental and theoretical behavior of simply
supported concrete slabs reinforced with glass fiber reinforced bars (GFRP) and
subjected to four-point monotonic loading. The slabs had dimensions that were
1750mm × 700mm with thickness varied between 100mm to 150mm. Experimental
work manufacturing GFRP bars and casting and testing of eleven specimens.
The reinforcement of the slabs had different ratios using different reinforcement
diameters. The flexural behavior of the tested slabs, ultimate deflection, and the
cracks patterns of the slabs reinforced using steel reinforcement were compared with
the others reinforced using GFRP bars which shows good enhancement.
Also, the structural behavior of testing slabs was compared by the developing
nonlinear finite element analysis models utilize the software ANSYS 2019 R1
program. There was good approval between the experimental and analytical
analysis.
GFRP reinforced concrete design is governed by serviceability limits and strain of
GFRP and steel bars and load-deflection mid-span and concrete were spotted.
