| Summary: | The use of fiber reinforced polymer (FRP) bars as an alternative to steel bars for
reinforced concrete (RC) structures is gaining acceptance among the structural engineers.
The investigation of structure performance of FRP-RC members has become a
critical issue. Extensive researches have been conducted to investigate the shear
behavior of RC members with FRP bar. However, the shear strength design of FRPRC
beams is similar to that of RC beams with steel bar except that the mechanical
properties of FRP bars which affect the shear strength design shall be considered. The
focus of this research is to investigate the shear behavior of FRP-RC beams. A total
of 18 RC beams were constructed and tested up to failure, the test beams included 10
GFRP-RC beams and 8 steel-RC beams. In order to realize the occurrence of the shear
failure, all tested beams were designed without stirrups. The test variables were the
reinforcement ratio (ρ), shear span to depth ratio (a/d), depth of beam (d), and concrete
compressive strength ( |
