摘要：

Based on the random vehicle loading spectrum and finite element method, this paper analyses the displacements and the fatigue performances in the tensile region of simply supported concrete T-beams, which are reinforced by the prestressed CFRP sheets. And it is showed that under the random vehicle spectrum the stresses decrease after the T-beam has been reinforced by the prestressed CFRP sheets; the fatigue life of T-beams has doubled to 2x107 compared with that before the reinforcement.
