This work consists on a comparative analysis between proceedings of brasilian standard NBR 8800 for design of steel structures, the american specification AISC/LRFD published december 27, 1999, the european prestandard prENV 1993-1-1: 20xx, the english standard BS 5950-1:2000, the german standard DIN 18800, the canadian standard CAN/CSA-S16.1 and criterion suggest for the revision of NBR 8800 aboutload combination, design resistance of tension members, columns and beams and width/thickness relationships to avoid local plate buckling of columns and beams. It will also be presented some information about the behavior of welded I and H shapes with flange edges flame-cut, largely used in Brazil. These sections have tension residual stress at flange edges and, for this reason, they have greater resistance to instability.
