The paper presents the experimental stand and the preliminary results of laboratory test concerning the analysis of the effectiveness of the strengthening of steel beams made of thin-walled sigma profiles by using the CFRP strips. The study includes six beams made of the cold-rolled sigma profiles with height of 140 mm, wall thickness of 2.5 mm and a length of 3 meters subjected to the uniform distributed loaded. Four beams have been strengthened with carbon fiber, while the other two were tested without strengthening for comparison of results. On the basis of the obtained results the evaluation of the accuracy of applied composite materials for strengthening of thin-walled structures was performed.
