heal.abstract	Steel beams and beam-columns are generally subjected to six different internal forces and moments if warping of the cross-section is neglected. Three of them, normal forces and bending moments on the strong and weak axes result in direct stresses, the other three, shear forces on the weak and strong axes and Saint Venant torsion result in shear stresses on the cross-section. Based on the well-known interaction formula for the rectangular cross-section, interaction formulae for all six internal forces and moments on box-cross sections are given. The formulae are derived for both partial and complete plastification of the cross-section. It is shown that the complete plastification of the cross-section is associated to torsion. The comparison of the results with the corresponding provisions of Eurocode 3 and the publication that is referred to in DIN 18800, part 1 shows that in both cases complete plastification is considered. It is shown further that the Eurocode 3 provisions are partly simplified, and therefore uneconomical, and partly wrong and unsafe.	en
