The widespread application of steel as a structural material in industrial and bridge construction highlights the importance of research into strengthening methods for steel structures made of hot-rolled profiles. This study presents laboratory tests conducted on bent hot-rolled C100 steel channels with a length of 3 meters. A total of eight beams were tested, of which the first two served as unstrengthened reference specimens. The remaining beams were reinforced using bonded carbon fiber fabric in three different configurations. The results of the experimental study indicate a negligible effect of this strengthening method on the increase in ultimate load capacity and strain reduction, while showing an approximate 22% reduction in horizontal displacements compared to the reference beams.
