Question:
How can I use springs for nodal supports in the design of sets of members in RF‑/STEEL EC3?
Answer:
To adjust nodal supports of sets of members, go to Window "1.7 Nodal Supports". You can adjust the nodal supports for the set of members there.
Left-click once next to the check box of the support condition that you want to adjust. A selection symbol appears where you can select the "Spring" type. Now, you can enter the spring properties.
