SUMMARY
The discussion focuses on calculating the section modulus of built-up members composed of W and WT shapes welded together about the x-axis. It confirms that the section modulus of individual sections cannot simply be added due to the lack of symmetry about the x-x axis. Participants conclude that a manual calculation is necessary to accurately determine the section modulus for such configurations.
