| As a new type, high technical of building reinforcement of carbon fiber reinforcedconcrete structure method and under the new social economic situation, this method has veryhigh research and promotion sense. Because of its light weight, high strength, corrosionresistance and convenient to construction, Carbon fiber material has been widely applied in thefield of structure reinforcement.For decades, the experts do a lot of research on reinforcedconcrete structure with carbon fiber material, the reinforcement theory and technology gotrapid development, at the same time, with the further development of finite element theory andthe maturity of the theory, the finite element analysis method gained more and more attention inrecent years. Based on summarizing the reinforced concrete structure reinforcement theory andmethod of the domestic and foreign scholars and based on the further exploration to find a moreeffective way of strengthening, the comparison between the experimental and finite elementanalysis shows the feasibility of this method.This paper first summarizes the background of carbon fiber reinforced concrete and theresearch status at home and abroad, briefly introduced the basic theory of reinforce in CFRP.Second, embedded reinforcement method is used to study strengthened beam and prestressedreinforcement beam which the effect of varying the prestressing level from0%to60%of theultimate strength of the CFRP on the overall flexural behavior of the beams was examined.fivekinds of working conditions of the beams were tested to find the deflection and ultimate load ofthe beams. By using the finite element model simulation, through the comprehensiveparameters impact analysis, the finite element calculation results and test results, verify thecorrectness and feasibility of the experiment. In this paper, the testing scheme and formulatedby the finite element solution can provide a reference for future further research andengineering application. |
