| Abstract: | The shear resistance of fifteen RC beams strengthened with the sheets of glassfibre reinforced plastics (GFRP) is tested. The shape of GFRP sheet, the form and the rate of strengthening are studied; the effect of shear span ratio of the beam on the shear bearing force and the rupture pattern of the strengthened beam are also studied. An arched truss model is adopted to explain the shear rupture mechanism of the beam strengthened with GFRP; and a formula is put forward for calculating shear bearing force of the RC beam strengthencd with GFRP sheet. |

| Keywords: | concrete beam glassfibre reinforced plastics strengthening of shear performance shear bearing force |
