Abstract

In this paper, the advanced analysis of 3D steel frames accounting for lateral-torsional buckling is presented. This analysis accounts for material and geometric nonlinearities of the structural system and its component members. Moreover, the problem associated with conventional advanced analysis, which do not consider lateral-torsional buckling, is overcome. An efficient way of assessing steel frame behavior including gradual yielding associated with residual stresses and flexure and second-order effect is presented. A case study shows that lateral-torsional buckling is a very crucial element to be considered in advanced analysis. The proposed analysis is shown to be an efficient and reliable tool ready to be implemented into design practice.
