| Abstract: | To reinforce old-bridges by CFRP is a high-efficiency, economical and safety method. The six destructive forms of T-beams are discussed in the paper, and a new distinguish basis of critical state, critical dosage of CFRP, critical height coefficient of concrete compressive region and compute method of conversion section are put forward. The design method is established according to the existing specifications for highway bridges. It has received satisfactory effects by applying to actual engineering. |
