Lateral torsional buckling design imperfections for use in non‐linear FEA

To perform geometrically and materially non‐linear analyses including imperfections for steel beam lateral torsional buckling, the size and shape of the geometric imperfection can be taken from EN 1993‐1‐1. The shape is prescribed as an initial bow along the weak axis of the section, excluding torsi...
