In order to research the shear behavior of glass fiber reinforced polymer (GFRP) reinforced concrete
beam with circular cross section, based on the test results of 36 concrete beams subjected to four-point loading
up to failure, the shear capacity and mechanical properties of deformation were analyzed comparatively between
GFRP reinforced concrete (GFRP-RC) beams and steel reinforced concrete (steel-RC) beams. Furthermore,
influencing factors of shear capacity of GFRP-RC beam with circular cross section were also investigated. The
test results indicate that the failure modes of GFRP-RC and steel-RC beams are the same, but the crack patterns
are slightly different. And, the shear capacity of GFRP-RC beam firstly increases with the reduction of shear
span ratio, and then decreases. In addition, it was found that the influencing coefficient of GFRP on concrete
increases with shear span ratio reducing.
