Knowledge Base Articles
The classification of cross-sections should determine the limits of the resistance and rotation capacity by local buckling of the cross-section parts. In EN 1999‑1‑1, 220.127.116.11 (1), four classes are defined.
Product Features Articles
With the activated option "Topology on form-finding shape" in the Project Navigator - Display, the model display is optimized based on the form-finding geometry. For example, the loads are displayed in relation to the deformed system.
Frequently Asked Questions (FAQ)
- How can I get the member end forces to design the connections?
- Which Dlubal Software programs are required to calculate membrane and tensile structures?
- I would like to analyze cable and tensile structures. Is it possible to use RFEM or RSTAB for this?
- In connection with the calculation according to the large deformation analysis, I get significantly smaller deformations than for the calculation according to the linear static or second-order analysis. How is this possible?
- I have performed a buckling analysis in RF-ALUMINUM. Where can I find the parameters that the module uses for the design?
- I would like to calculate the results, such as ordinates, static moments, stresses, at a specific location of a cross-section. What should I do?
- How can I calculate stresses in SHAPE‑THIN?
- Is it possible to use a cross-section from SHAPE‑THIN 9 in older versions of RFEM or RSTAB?
- It is not possible to design a SHAPE‑THIN cross-section due to invalid symmetry. What is the cause and how can I fix it?
- How does the calculation of the moments of inertia differ when the cross-section consists of several unconnected or connected partial cross-sections?
