摘要
高强经编聚酯纤维筋是一种新型FRP筋。为深入研究高强经编聚酯纤维筋混凝土梁弯曲性能,通过5根高强经编聚酯纤维筋混凝土梁和1根钢筋混凝土梁的弯曲试验,对高强经编聚酯纤维筋混凝土梁正截面抗弯性能进行了研究。结合试验梁结果,探讨了抗弯承载力计算方法,并与实测值进行了比较,分析了高强经编聚酯纤维筋增强混凝土梁的裂缝分布形态、最大挠度等特性。
Strong warp knitting polyester fiber bar is a new type of FRP bar. In order to research the bending properties of concrete beam with strong warp knitting polyester fiber bar,five concrete beams reinforced with strong warp knitting polyester fiber bars and one concrete beam reinforced with steel bars were made and investigated in flexure. Based on the experimental study,the calculating method on bending capacity of concrete beams strengthened with strong warp knitting polyester fiber bars was analyzed. The cracks distribution pattern and load-deformation and maximum deflection of concrete beams were analyzed.
