| 要旨 | Strengthening methods for reinforced concrete (RC) structural elements are of significant interest from researchers and engineers worldwide. This paper presents an experimental study on the flexural behavior of RC beams strengthened by a high-performance textile reinforced mortar (TRM) layer and examined for first time under cyclic loading. The cyclic loads were conducted referring to an on-site load method of existing RC structures as per ACI 437R-03. The main concerned parameters affecting the flexural behavior of TRM-strengthened RC beams were studied, including the loading type, the pre-cracking procedure, and the number of layers of fiber mesh. The failure modes and the deformation ability of the tested beams were analyzed in detail based on test observations and analysis results on deformation of the beams. The results verified the strengthening effectiveness of the TRM layer for RC beams under cyclic loading. |
