The paper presents the results of experimental research into the use of post‐installed threaded rods as additional reinforcement. An increase in load‐carrying capacity of up to 64% was obtained for strengthened corbels compared with unstrengthened corbels (reference corbels). Calculations were performed of the load‐carrying capacity of corbels using a model developed on the basis of the literature and the obtained results were compared with results calculated according to the EN ‐1992‐1‐1. Strain diagrams for primary reinforcement, stirrups, and the compressed surface of concrete are presented, alongside with a description of the development of cracking and photographs of the corbels after failure. In the second section, publications about the calculation of the load‐carrying capacity of corbels and on different reinforcement methods are quoted.
