	This paper presents the course and results of a research programme aimed at the determination of the design buckling resistance of an axially compressed RHS column strengthened using two shorter U-sections. Connections of the tube and the channel branches were fabricated using BOM blind fasteners. Results of the experimental tests demonstrated the satisfactory efficiency of the performed strengthening of the tubular bar. Parametric analyses performed based on the validated theoretical model allowed the identification of the key factors influencing the effectiveness and economic efficiency of the strengthening process.
