| Abstract: | The bearing capacity, development of crocks and rigidity of reinforced concrete beams are discussed by bolting steel plates through contrasting experiment of static load between strengthened beam and non-strengthened beam. A convenient design formula is given in this paper, and results indicate that the formula provides a good reliability. |
