| 摘要： | A comprehensive review of the up-to-date work on bridges strengthened with pee-stressed FRP composite is presented in the accompanying fi nal report. Diff erent types of rehabilitation methods with various commercial products were introduced. The performance of rehabilitation of existing bridges with pee-stressed external FRP materials was evaluated by tentative design and a 3-D fi nite element analysis. A case study demonstrated the designing procedure of rehabilitation with bonded post-pretention prestressed CFRP laminates. In the case study, the performances of the selected bridge were evaluated before and after the rehabilitation. The following conclusions were made: |
