In SHAPE‑THIN 9, it is possible to model cold-formed sections and determine the effective cross-sections according to EN 1993‑1‑3 and EN 1993‑1‑5. This is not possible in SHAPE‑THIN 8.
Difference Between SHAPE-THIN 9 and SHAPE-THIN 8
What is the difference between SHAPE-THIN 9 and SHAPE-THIN 8?
Ms. von Bloh provides technical support for our customers and is responsible for the development of the SHAPE‑THIN program as well as steel and aluminum structures.





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

For design objects, you can optionally display sags or extreme results.

The results of solid stresses can be displayed as colored 3D points in the finite elements.

The number of degrees of freedom in a node is no longer a global calculation parameter in RFEM (6 degrees of freedom for each mesh node in 3D models, 7 degrees of freedom for the warping torsion analysis). Thus, each node is generally considered with a different number of degrees of freedom, which leads to a variable number of equations in the calculation.
This modification speeds up the calculation, especially for models where a significant reduction of the system could be achieved (for example, trusses and membrane structures).
