In the paper the results of laboratory tests and numerical analyzes of thin-walled CFRP-reinforced beams are presented. Full scale laboratory tests included six sigma [3] beams 140 mm high and 2.5 mm wall thickness, 3 meters long. The laboratory specimens were assumed as simply supported, single-span beams subjected to a uniformly distributed load. Four of tested beams were reinforced with carbon fiber tapes. Numerical models of the considered beams were developed in the program Abaqus and subjected to validation and verification based on laboratory results. Special attention was paid to the evaluation of the possibility of increase the load capacity of the beams by appropriate position of CFRP tape.
