Eurocode 3

Go to Standards → Main → Eurocode3 and add the required module (e.g., Eurocode3 Members). If members/plates/connections are not recognized automatically, run the relevant tools (e.g., Beam Member Finder, Panel Finder, Connection Finder) and re-check.

Member checks cover common steel sections including I-beams, channels, tees, symmetric angles, circular/rectangular tubes, and circular/rectangular bars.
Note: Bending checks are not performed for L-shaped members (angles) in this module.

Member checks are intended for Class 1–3 sections. If a section becomes Class 4, you can either handle slender behavior via plate buckling workflows, or use the option that treats Class 4 as Class 3 (conservative approach with adjusted yield where applicable).

Usually it’s one of these: the members/plates were not recognized, key properties are missing (e.g., fillets, net area for holes, material yield/tensile values), or the geometry falls outside the supported cases. Use Preview Not Supported Elements to locate them, then fix recognition (Finder tools) or complete missing inputs.

SDC Verifier uses Beam Member Finder data automatically. Buckling checks use member length definitions for Ly/Lz (and strong-axis length for L_LT). For lateral-torsional buckling you can choose the method (General Case, Rolled/Equivalent Welded, or the worst of the two), and set the correction factor Kc (calculated via tools or set to 1 if needed).
