| 摘 要： | 通过对5根玄武岩纤维加固混凝土梁的试验,研究了玄武岩纤维布对梁的抗剪承载力的影响和作用。主要考虑的参数有:玄武岩纤维布的宽度和间距、玄武岩纤维布的粘贴层数等因素。试验结果表明,玄武岩纤维布能够明显提高钢筋混凝土的抗剪承载力,并且能改善构件的变形能力。提出了适合工程应用的承载力计算设计公式。

| Abstract: | Five simply supported beams strengthened by basalt fiber reinforced polymer(BFRP)are tested.The experimental factors are width and spacing of BFRP strips,layers of BFRP.The experimental results indicate that BFRP can evidently increase the shear strength and improve the ductility of these specimens.A design formula is proposed. |

| Keywords: | BFRP sheets RC beams strengthening shear strength |
