Abstract

This paper proposes a way to local buckling check according to Eurocode-3 for plastic-hinge analysis of 3-D steel frames with I-shaped sections. A useful technique for determination of stress distribution on cross-sections under axial force and bi-bending moments is proposed so that the concept of classification of cross-sections may be directly used. Cross-section requirements for plastic global analysis in Eurocode-3 are applied for a local buckling check. Two three-dimension steel frames with diverse configurations of member size are considered by a second-order plastic-hinge analysis with the proposed technique. Useful information for checking local buckling of a large number of plastic-hinges is completely presented.
