摘　　要：为解决海港工程中钢筋混凝土结构钢筋锈蚀问题,采用纤维增强塑料筋(GFRP)代替传统钢筋,开展了以GFRP筋的抗拉强度、平衡配筋率、最小配筋率、挠度为控制条件的不同配筋情况下GFRP筋增强混凝土梁的力学性能试验,对GFRP梁在荷载作用下的截面特性、裂缝分布、极限承载力和破坏形式等力学特性进行深入研究,为进一步在工程中开展应用提供了试验参考。To address the reinforcement corrosion issue of concrete structures in harbor engineering, Glass Fiber Reinforced Polymer （GFRP） is used to replace the traditional steel. A series of mechanical performance tests of GFRP reinforced concrete shallow beams have been carried out under such control conditions as tensile strength, balanced reinforcement ratio, minimum reinforcement ratio, and the deflection etc., so as to further study the cross-section characteristics, crack distribution, ultimate bearing capacity and damage forms of GFRP beams under load and also to provide a test reference for further application in engineering.

关 键 词：GFRP筋 极限承载力 破坏形式
