The chosen results of numerical analysis of middle and higher strength structural steels using in compression members are presented. The homogeneous cross-sections of the members with web slenderness Betaw = 40, 48, 60, 80, 120; member length L = 3,0; 4,0; 5,0 and 6,0 m and structural steels S235, S275, S355, S420 and S460 are assumed. The full reference plastic load Npl, local post-critical load Nul and global buckling load Nu,y and Nu,z for all members by actual Slovak Standard STN EN 73 1401:1998 and by new European standards EN 1993-1-1:2005 and EN 1993-1-1:2006 for the design of steel structures, taking account the geometrical optimalization determined. The obtained numerical results are compared and analyzed from the economical point of view.
