摘要
通过对 15根玻璃纤增强塑料 (GFRP)片材加固混凝土梁的抗剪试验 ,研究 GFRP片材的形状、加固方式、加固率 ,以及梁的剪跨比对加固梁抗剪承载力和破坏模式的影响 .文中采用拱形桁架模型解释 GFRP加固梁的剪切破坏机理 ,提出
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.
