	Summary:
	In the paper, a simplified method for design of circular composite CFT columns according to the European standard for deisgn of composite steel and concrete structures – Eurocode 4 is presented. Veri¬fication of the column section capacity under axial compression and bending is based on the concept of limit states and determination of the N-M interaction curve. For eight the most common in practice CFT columns, continuous N-M interaction curves are constructed. In addition, for these selected sections, the influence of the variation of the concrete and steel classes on the column cross-section capacity is analyzed. Given interaction curves simplify the design of composite columns and the choice of dimensions of CFT column and its steel and concrete classes.
