摘要(Abstract)：

随着纤维增强复合材料(FRP)对既有建筑物的加固与修复技术的运用越来越广泛,使得被加固或修复构件、结构的使用寿命得到延长,因此FRP与被加固构件一起必然要受到长期荷载的作用。收集了国内外已有的关于FRP加固钢筋混凝土梁(简称RC梁)徐变性能的研究文献,从FRP材料的蠕变研究现状以及FRP加固RC梁徐变性能的研究现状这两个方面进行总结,发现现有的关于FRP加固RC梁徐变性能的研究主要集中在FRP单一材料的蠕变性质,以及直结加固梁的徐变研究,对接近实际工况的加固前有损伤的梁的徐变性能研究较少。
With the broad use of fiber reinforced polymer(FRP) for the strengthen and repairing of existingbuildings, the service life of reinforced or repaired structures has been prolonged, so that the FRP must besubjected to long-term loads together with the member to be strengthened. The current research on thecreep of FRP-strengthened reinforced concrete(RC) beams were collected, the current situation of FRP ma-terial creep research and the creep study of FRP-strengthened(RC) beams were summarized. It is foundthat the existing researches about creep behavior of FRP-strengthened RC beams are mainly focused on thecreep properties of single FRP material and the creep study of the beams strengthened before loading. Studynear the actual condition of the creep behavior of the FRP-strengthened RC beams is less.
