纤维增强复合材料抗剪加固混凝土梁试验研究进展

Review of experimental researches on concrete beams shear-strengthened with fiber reinforced polymer

基于纤维增强复合材料(FRP)抗剪加固混凝土梁试验研究成果,对3种不同FRP抗剪加固方法进行总结。介绍了外贴FRP(EB)、表面嵌入FRP(NSM)抗剪加固方法的试验研究历史和现状,总结了这两种方法的优缺点。重点阐述了截面中部插入FRP(ETS)抗剪加固方法的试验研究进展,提出了加强FRP抗剪加固混凝土梁试验研究的建议。

This paper summarizes three different FRP shear reinforcement methods based on the available research results of FRP shear reinforcement beams. The experimental investigation history of externally bonded method and near surface mounted method is introduced and the advantages and disadvantages of each method are discussed. The article also points out that the ETS technique is a blank in domestic research and application. The experimental study history and status of the embedded through-section method are summarized and expounded according to the existing foreign literature in this field, in order to provide a reference for relevant domestic research and application. Finally, some suggestions of experimental study on FRP shear-strengthened are presented, and the research direction is also prospected.
