| Abstract: | Calculating methods of cracking moment, ultimate moment, stiffness of the beams strengthened by steel plate are offered according to the non-linear relationship between stress and strain of concrete. The theoretical and experimental results are compared and analyzed, In addition, the proposals of checking the separating stress, bonding lengthen, strong shearing and weak bending are supposed for the strengthened concrete beams could fail because of bending. |
