In RFEM, RSTAB, and SHAPE-THIN, you can use formulas to determine a numerical value.
The material allocation for hybrid SHAPE‑THIN cross‑sections can be selected easily in RFEM and RSTAB. The prerequisite for this is the allocation of different materials to the cross‑section elements in SHAPE‑THIN.
The network-capable Project Manager controls the projects of all Dlubal Software applications in one central location.
General thin-walled cross-sections often have asymmetrical geometries. The principal axes of such sections are then not parallel to the horizontally and vertically aligned axes Y and Z. When determining the cross-section properties, the angle α between the center-of-gravity axis y and the principal axis u is determined in addition to the principal axis-related moments of inertia.
In SHAPE-THIN 8, the effective cross-section of stiffened buckling panels can be calculated according to EN 1993-1-5, Cl. 4.5.
The critical buckling stress is calculated according to EN 1993-1-5, Annex A.1 for buckling panels with at least 3 longitudinal stiffeners, or according to EN 1993-1-5, Annex A.2 for buckling panels with one or two stiffeners in the compression zone. The design for torsional buckling safety is also performed.
The material database in RFEM, RSTAB and SHAPE-THIN contains steels according to the Australian standard AS/NZS 4600:2005.

The printout report corresponds to the high standards of RFEM and rstab/rstab-9/what-is-rstab RSTAB. Modifications are updated automatically.
I get a warning that a file created with RFEM, RSTAB, or RSECTION contains a virus or a Trojan horse. What should I do?
How are the section moduli about the y- and z-axis calculated in RSECTION 1, SHAPE‑THIN, and SHAPE‑MASSIVE?
How can I show or hide the printout report navigator?
How do I get the current authorization file for RFEM 5, RSTAB 8, and other stand-alone programs?
Can I import a SHAPE‑THIN cross-section into RFEM 6 or RSTAB 9?
Where on the Dlubal extranet can I download my RFEM/RSTAB authorization file?
