摘要
纤维增强塑料(FRP)筋具有抗拉强度高、重量轻、抗腐蚀、耐疲劳等特点,对FRP筋代替混凝土结构中易受腐蚀的钢筋进行研究,这对改善钢筋混凝土结构的某些性能和拓宽工程应用范围,具有明确的工程意义。本文对FRP筋混凝土受弯梁进行了正截面受力分析,并推导了相关的计算公式,最后用具体算例的计算结果与试验结果进行了比较。结果表明,计算值与试验值吻合较好,为今后进一步研究FRP筋受弯构件提供了参考。
Fiber reinforced plastics （FRP） rebars have the characteristics of high tensile strength, light weight, strong resistance to corrosion and fatigue loadings, etc. Therefore, it＇ s necessary to study the replacing of corrosive steel rebars with FRP rebars in the concrete structures. As a result, it has clear engineering significance for improving some performance of reinforced concrete structures and enlarging the range of engineering application. In this paper, force analysis of cross section of concrete beams in bending reinforced with FRP rebars is studied and the relevant calculation formulas are derived. At last, the calculation results are also compared with the experimental results. The result shows that the calculation results have good agrcetment with the experimental results, which may give reference to research of members in bending reinforced with FRP rebars in the future.
