Analysis Methods Investigation of Steel Frames Accounting for Local Buckling
Second-order inelastic analysis should be directly performed in order to overcome the difficulties of the conventional approach, but most of these analyses assume the section to be compact, and do not account for the degradation of the flexural strength caused by local buckling. Since the sections of real structures are not always compact, the analysis should be improved to consider local buckling. The objective of this paper is to investigate the plastic-zone and plastic hinge analysis methods of steel frames accounting for local buckling with nonlinear shell elements and design specifications as AICS-LRFD and Eurocode 3, which may be used as reference for the further study.
