| 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。

| Abstract: | 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. |
