Yes, you can. In RFEM 5 and RSTAB 8, you can use the cross-sections created with SHAPE‑THIN 8 and SHAPE‑THIN 9.
SHAPE-THIN 9 in Combination with RSTAB 8
Can I use SHAPE-THIN 9 in combination with RSTAB 8?
Mr. Faulstich is responsible for the quality assurance of the RFEM program and provides customer support.





The material database in RFEM, RSTAB and SHAPE-THIN contains steels according to the Australian standard AS/NZS 4600:2005.

Want to automatically consider steel joint stiffness in your global RFEM model? Utilize the Steel Joints add-on!
Activate joint-structure interaction in the stiffness analysis of your steel joints. Hinges with springs are then automatically generated in the global model and included in subsequent calculations.

In the ultimate configuration of the steel joint design, you have the option to modify the limit plastic strain for welds.

The "Base Plate" component allows you to design base plate connections with cast-in anchors. In this case, plates, welds, anchorages, and steel-concrete interaction are analyzed.
What could be the reason?
