摘要:
为研究玄武岩纤维的掺入对钢筋混凝土梁裂缝和变形的影响，以玄武岩纤维体积掺率和纤维长度为变化参数，设计制作5根试验梁，通过静载试验获得了玄武岩纤维混凝土梁在受力过程中的裂缝分布、裂缝宽度和跨中挠度等试验数据，并与普通混凝土梁进行对比。基于试验数据分析结果提出了玄武岩纤维混凝土梁最大裂缝宽度和短期刚度计算方法。结果表明：玄武岩纤维的掺入可有效阻止钢筋混凝土梁裂缝的开展并提高梁构件的延性。
Abstract:
In order to study the influence of mixing of basalt fiber on crack and deformation of reinforced concrete beams, five test beams were made with the parameters of volume ratio and length of basalt fiber, and the static load tests were carried out. The test data of crack distribution, crack width and midspan deflection of basalt fiber reinforced concrete beams in the process of stress were obtained and compared with common concrete beams. Based on the analysis results of test data, the calculation methods of maximum crack width and short term stiffness of basalt fiber reinforced concrete beams were presented. The results show that the mixing of basalt fiber can effectively prevent cracks extension in reinforced concrete beams and improve the ductility of beams.
