| Abstract: | The technique of concrete structure strengthened with prestressed CFRP sheet is an effective technique anchorage method is an important problem in this technique. The anchorage effect of different layout of U-shapod CFRP sheets is given by load-testing 7 concrete beams. The principles of placing U-shaped CFRP sheets are proposed, which may benefit the design and construction of this technique. |
