A steel roof girder (IPE 360 in S355JR, span L = 8.0 m) is subjected to positive bending moments from gravity loads. The compression flange is unrestrained along its span between end supports. What stability failure mode must the metal construction master calculate according to SIA 263?

Local flange crushing (Flanschquetschung) without lateral displacement Pure plastic torsional warping (Wölbkrafttorsion) without any flexural bending component Punching shear failure (Durchstanzen) of the IPE web Lateral-torsional buckling (Biegedrillknicken), determined by calculating the ideal elastic critical moment Mcr and applying the reduction factor chi_LT based on the non-dimensional slenderness lambda_bar_LT

Correct Answer:

Lateral-torsional buckling (Biegedrillknicken), determined by calculating the ideal elastic critical moment Mcr and applying the reduction factor chi_LT based on the non-dimensional slenderness lambda_bar_LT
