Using this combination, a non-linear 2 nd Order calculation is executed using Timoshenko’s method.<br />
The additional moment can be easily calculated as follows:<br />

When performing a Steel Code Check on the column for the non-linear combination, this can be<br />
verified. The critical check is performed at 2,5m and has the following effects:<br />
The additional moment thus corresponds to the moment calculated by <strong>Scia</strong> Engineer.<br />
As seen in the diagram, Path 3 is followed: the buckling shape serves as a unique global and local<br />
imperfection. This implies that only a section check and Lateral Torsional Buckling need to be checked.<br />
Since LTB is negligible with this small bending moment, only a section check is required:
