| Abstract: | The entire process on the prestressed carbon fiber sheets strengthened once and twice loading beams is analysed. The correlation computation covers the preparatory work before prestressing of CFRP sheets and experiment stages. In view of different operating modes, the authors derive relevant formulae for each stage. Compared with the test results, it can be concluded that the theory is derived correctly. |
