This paper presented an example of CFRP applied to strengthen many special beams and described the full process for design and construction,especially presented an easy design method of how to calculate the ultimate capacity of the flexural beams. The result of reinforcement has been proved successful. It shows that the application of CFRP technique will have a good prospect.
