Answer:
The software features allow you to consider the decline of loads in RFEM/RSTAB, and to design the following member types in the add-on modules:
- Single member: A member has two nodes, one at the beginning and one at the end of the member.
It is possible to connect several single members to create a continuous member or a set of members.
- Continuous member without intermediate cutting at the nodes
Both options lead to the same results (internal forces, stresses, and so on).
To prevent the automatic division of the existing member, it is necessary to disable the option "Auto Connect Lines/Members" in the shortcut menu, which you can open by right-clicking the model window.
