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.
