Visual Help for Defining Support Conditions for Sets of Members in a Design According to EN 1993-1-1, Clause 6.3.4

Technical Article on the Topic Structural Analysis Using Dlubal Software

Technical Article

In RF‑/STEEL EC3, sets of members are calculated according to the General Method (EN 1993‑1‑1, Cl. 6.3.4), together with the stability analysis. To do this, it is necessary to determine the correct support conditions for the equivalent structure with four degrees of freedom. In most 3D models today, you can quickly lose track of the location of a set of members in the system.

In RF-/STAHL EC3 gibt es daher in der Maske 1.7 eine graphische Anzeige der Struktur. The display of the structure is interactive; you can zoom and move the graphic. The buttons below the graphical display are very useful. You can use them to hide the rest of the structure or show it in the background. We recommend, in particular, showing the local coordinate system of the set of members, including the supports defined in window 1.7. Thus, you can easily avoid errors when defining the boundary conditions.
