EXPERIMENTAL STUDY ON SHEAR BEHAVIOR OF BFRP REINFORCED RAC BEAMS

Abstract

Abstract: The shear performances are presented for recycled aggregate concrete (RAC) beams reinforced with basalt fiber-reinforced polymer (BFRP) bars. Four beams reinforced with BFRP bars with and without stirrups were constructed and tested. The failure modes, load-deflection, load-strain behavior of longitudinal reinforcement and stirrups, and shear capacity were discussed respectively. And, a comparative analysis was carried out with four steel bars reinforced RAC beams with the same size. It was observed that all the BFRP bars reinforced concrete beams failed in shear, but the steel bars reinforced RAC beams is changed from shear failure to flexural failure after being configured the stirrups. Stirrups on the improvement of BFRP bars reinforced beam shear capacity is more significant. The deformability of BFRP bars reinforced concrete beams with stirrups is better than that of beams without stirrups, and the shear resistance ance effect of the stirrups is related to the position and inclination of the shear cracks in the beam.

Key words: beams, basalt fiber-reinforced polymer, recycled aggregate concrete, stirrups, shear capacity
