摘　　要：在腐蚀环境中,钢筋的锈蚀给结构带来很多危害,而GFRP筋具有良好的耐腐蚀性,用GFRP筋取代钢筋能很好地解决钢筋易锈蚀的问题。但是GFRP筋是热固性材料,不适合在现场加工。本文提出采用装配式的结构形式对GFRP筋混凝土进行施工,并对装配式GFRP筋混凝土梁-板节点进行了设计,再通过ABAQUS模拟分析了节点的力学性能,最后提出几种对梁-板节点进行加固的措施。研究结果为GFRP筋在海岛工程中的应用可行性提供了依据和参考。In the corrosive environment, the corrosion of steel bars brings a lot of damage to the structure, and GFRP tendons have good corrosion resistance,which indicates the replacement of steel bars with GFRP tendons can solve the problem of easy corrosion of steel bars. However, GFRP tendons are thermosets, which are not suitable for processing in the field. In this paper, the use of pre - fabrication in GFRP reinforced concrete construction was proposed, the beam and slab joints of pre - fabricated GFRP reinforced concrete were designed, the mechanical properties of the nodes were analyzed by ABAQUS, and several measures were proposed to reinforce the joints. The study results provides a basis for study of the application feasibility of GFRP tendons in island projects.
