| Abstract: | The relation between the moment and curvature of steel-bonded concrete beams is derived from using a damage model for concrete and the position changing regularity of the neutral axis is made out, Thus, a theoretical basis for the design of steel-bonded reinforcement is provided. The bending damage of the beams before and after steel-bonded reinforcement is compared with that of the plain concrete beams. The results illustrate that the bending resistance ability of the beams after steel-bonded reinforcement in-creases markedly, which is in agreement' with experiments. |
