目前越来越多的纤维增强塑料筋（FRP）被应用于土木工程当中，把 FRP 筋作为一种钢筋的替代品。 FRP 筋的屈服点不明显而且其弹性模量也比较低，这就造成了荷载下的 FRP 筋混凝土梁会产生较大的变形和裂缝宽度。为了研究影响 FRP 筋混凝土梁受弯性能的各方面因素，采用大型通用有限元分析软件 ABAQUS 对配有 FRP 受拉筋的混凝土梁进行建模并分析其受弯性能。数值模拟结果与他人的实验结果有较高的吻合度，同时分析了影响 FRP 筋混凝土梁受弯性能的一些因素。

Nowadays FRP bars are widely applied in the civil engineering structures as a substitute of steel bars .The low elastic modulus and non - yielding characteristics of FRP bars result in large deformations and wide cracks in concrete beams reinforced with these bars under loading .In order to study the factors that influencing the bending performance of FRP reinforced concrete beams ,the finite element software ABAQUS was used to establish a model of this beam and its bending properties was analyzed as well as the influencing factors .The results of the numerical simulation are in good a-greement with the experimental results of other researchers .
