摘　　要：对纤维增强聚合物(FRP)格栅加筋混凝土梁的弯曲行为和破坏模式进行了试验研究。采用复合材料制备了3条纵向肋和4条纵向肋2种不同构造的平面正交格栅,埋入混凝土梁,并对加筋混凝土梁进行四点弯曲试验。结果显示,在本研究采用的混凝土梁尺寸条件下,3根纵向肋的复合材料格栅加筋梁以弯曲破坏模式为主,而4根纵向肋的格栅加筋梁则以局部剪切破坏模式为主。试验结果表明,3根纵向肋的格栅充分发挥了复合材料的抗拉特性,具有更高的加筋效率。This paper experimentally investigates the flexural behavior and failure mode of fiber reinforced polymer （FRP） grid reinforced concrete beams. The two types of grids are used to reinforce concrete beams, one having 4 longitudinal ribs and the other having 3 longitudinal ribs. Four-point bending test of the reinforced concrete beams is conducted. The test results show that the grid with 3 longitudinal ribs is more effective than that with 4 longitudinal ribs in reinforcing concrete beams for the beam dimensions investigated in this study.
