| Abstract: | Reinforced concrete beams with an extended end, which are strengthened with U-jackets CFRP in negative moment area, are tested in laboratory by parallel experimentation. The properties of mechanics and the characteristics of failure are investigated under different strengthening conditions including the anchored and unanchored CFRP with different adhesion heights. On the basis of the analysis of the experimental results, the mechanics of strengthening with CFRP has been studied. Some suggestions, which claim attention in rehabilitation design and engineering practice, are proposed. |
