•The analytical design method for calculating the load-carrying capacity of strengthened beams.•Evaluation of the influence of the stiffness of the bond between concrete and external FRP.•Comparison of the experimental and calculated results.•Statistical assessment of proposed design method.
This article analyses the load-carrying capacity of reinforced concrete beams strengthened with external FRP reinforcement. It provides a method for calculating the load-carrying capacity of strengthened beams. The calculation method enables to assess the influence of the bond slip on the load-carrying capacity of beams. A database has been created for experimental results. Calculations of the load-carrying capacity of strengthened beams have been made. The received theoretical results have been compared to the experimental ones. Statistical evaluation of the calculation method for load-carrying capacity has been carried out. The comparative and statistical analysis of the received results shows that the calculated load-carrying capacity of strengthened beams is similar to the one received in the course of experiments.
