Based on the differential element method, considering transfer of bond stress between corroded steel bar and concrete, and the compatibility of cross-section strain before and after bond stress transfer is considered, the deflection calculation model of corroded RC beams strengthened by steel plates and FRP is proposed in this paper. To validate it, the testing results in existing literatures and this study, are compared and analyzed. The results show that under different loading levels, compared with the strengthened beam without considering b...
