摘要：纤文增强复合材料FRP(Fiber Reinforced Plastics )的加固是用胶黏剂把FRP粘贴在结构外部或嵌于结构内而进行加固的一种方法，可以提高构件的承载能力等受力性能。从上世纪80年代左右，世界各国的研究人员经过试验以及工程实例对于FRP对结构的加固做了很多研究验证，证明了FRP加固的有效性。24489

Structural Concrete FRP shear reinforcement methods
Abstract：FRP( Fiber Reinforced Plastics )reinforcement is method that adhesive the FRP outside the structure, which can improve the bearing capability of the structure.1980s,scholar all over the word to do a lot of experiment sand through the engineering example to verification that fiber reinforced plastics can reinforcing the structure, also improved that FRP can replace steel to reinforce structure.Based on the research of scholars at home and abroad, and organize experimental study, summarized the status of the fiber-reinforced composite shear reinforcement for concrete structures. FRP reinforcement detailed manner, calculation model, the calculation method or the like. And reinforcement of existing methods, models and calculation methods were compared and analyzed. FRP concrete has been discussed paste form, anchoring situation. And for FRP shear reinforcement in practical engineering problems encountered, depth sorting, summarizing, and put forward feasible suggestions. This paper also studied the current status of the countries were to a certain extent, finishing and presentation, although the progress of research and made an example of domestic narrative; For the study, the results of international research has also made an example narrative. As part of the national standards for calculating and summarizing. Finally, the current rapid development was contingent on the immature, imperfect technology that provides some basic research, or provide some reference for subsequent studies.
