FRP混凝土梁的抗弯性能研究

钢筋的锈蚀一直是影响混凝土结构安全性、耐久性的主要原因。纤维增强聚合物(FRP)因具有耐腐蚀性好,质量轻、强度高的特点,被认为是可以替代钢筋的理想材料。然而,纤维材料由于材性不同会导致使用性能上存在较大的差异,因此文章采用等刚度原则研究了不同FRP筋在混凝土梁中的抗弯性能表现,试验的结果可为筋材在设计使用时提供参考。

Study on Flexural Behavior of FRP Concrete Beams

The corrosion of steel bar has always been the main reason to affect the safety and durability of concrete structures.Fiber reinforced polymer(FRP)is considered as an ideal material to replace steel bar because of good corrosion resistance,light weight and high strength.However,different properties of fiber materials will lead to great differences in service performance.Therefore,the principle of equal-rigidity is adopted in the paper to study the flexural performance of different FRP bars in concrete beams.The test results can provide reference for the design and use of the bars.
