Visual Help for Defining Support Conditions for Set of Members in Design According to EN 1993-1-1, Clause 6.3.4
Tips & Tricks
In RF‑/STEEL EC3, sets of members are calculated according to the General Method (EN 1993‑1‑1, Cl. 6.3.4) together with stability analysis. For this, it is necessary to determine the correct support conditions for the equivalent structure with four degrees of freedom. In today's usual 3D models, you can quickly lose track of the location of the set of members in the system.
Therefore, there is a graphical display of the structure in Window 1.7 in RF‑/STEEL EC3. The display of the structure is interactive, you can zoom and move the graphic. The buttons below the graphical display are very useful. Using them, you can hide the rest of the structure or show it in the background.
Especially recommendable is to show 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.
