Abstract

Nowadays, retroftting reinforced concrete with FRP fbers is regarded as a globally signifcant issue. In reinforced concrete beam, the shear failure mode is more dangerous than fexural failure mode. Because this thin and sudden mode occurs without any pre-warning, diagonal shear cracks are wider than fexural cracks and preventing their expansion is rather diffcult. In the present study, the concrete beams are retroftted with GFRP fbers through a common method. Then, the beams have four- point bending test until the premature failure occurs. This phenomenon is relatively prevented through retroftting along the shear. The failure of beams are examined here.
