摘要
FRP作为一种新型高性能的结构材料,具有轻质、高强和抗腐蚀等特点,在土木工程中是一种具有发展前景的新型预应力筋用材。对FRP筋预应力混凝土梁的结构延性、抗弯性能、抗剪性能和长期性能等关键问题进行了仔细的分析总结,并对今后拟开展的研究工作提出了建议。
As a new structural material,FRP(fiber reinforced plastics) features light weight,high strength,corrosion resistance,etc.,and have a bright future when used as a new type of prestressing tendon in engineering structures.Based on analysis of literature,this article mainly analyses the key problems in the application of FRP prestressed concrete beam,such as ductility,flexural behavior,shear behavior and long term performance.Finally,advices for advanced research are provided.
