摘要
对普通钢筋混凝土梁和掺加了改性聚丙烯纤维后的钢筋混凝土梁进行了弯曲试验研究.试验研究表明,改性聚丙烯纤维可以在一定程度上提高梁的抗裂性能和正截面承载力.分析了纤维的掺入对钢筋混凝土粱的抗裂性能及正截面承载力的影响机理.
Bending experimentation on the normal reinforced concrete beam and the reinforced concrete beam after mixing a changed polypropylene fibre is studied. Result of the experimentation indicates that the changed polypropylene fibre can improve crack resistance and bearing capacity of the right section to an extent.The influence mechanism of the mixed fibre on crack resistance and bearing capacity of reinforced concrete beam are analyzed.
