This study aims to compare different design methods for assessing lateral-torsional buckling resistance of steel girders.
Investigates design approaches specified in EN 1993-1-1:2006 and EN 1993-1-1:2022.
Uses a numerical application on an IPE 400 beam.
Compares results from general methods and simplified procedures.
The direct simplified procedure results in the most conservative resistance.
Alternative methods reveal significant differences in design bending resistances.
Specific conditions are identified where simplified approaches may become unconservative.
