| 摘 要： | 为了获取玄武岩纤维布加固损伤混凝土梁的抗剪性能参数，并为玄武岩纤维布加固损伤混凝土梁的设计与施工提供理论依据，通过试验分析，研究了不同剪跨比、加固量、初始荷载等情况下梁的抗剪承载力变化规律，提出了玄武岩纤维布加固损伤混凝土梁的抗剪承载力修正计算公式。试验结果表明，梁的抗剪承载力受锚固方式、初始荷载和剪跨比的影响较大，采用玄武岩纤维布加固钢筋混凝土梁后，可以有效提高梁的抗剪承载力。

| Abstract: | In order to acquire the parameters of shear performance of RC beam strengthened with BFRP and provide theoretical gists for design and construction , shear capacity of RC beam strengthened with BFRP sheet is analyzed for different shear span ratio , number of BFRP sheet layer and pre-loading program within experimental works.Revised formula is presented for calculating shear bearing capacity of RC beam strengthened with BFRP . Experimental results shows that BFRP can improve shear bearing capacity of beam , and shear bearing capacity is affected by anchoring method , initial load and shear span ratio . |
