Schematic representation of the temperature-time curve according to the simplified natural fire model
SHAPE-THIN determines the effective cross-sections according to EN 1993-1-3 and EN 1993-1-5 for cold-formed sections. You can optionally check the geometric conditions for the applicability of the standard specified in EN 1993‑1‑3, Section 5.2.
The effects of local plate buckling are considered according to the method of reduced widths and the possible buckling of stiffeners (instability) is considered for stiffened sections according to EN 1993-1-3, Section 5.5.
As an option, you can perform an iterative calculation to optimize the effective cross-section.
You can display the effective cross-sections graphically.

- Why are the equivalent member designs grayed out in the Stability tab when activating the plastic designs by using the partial internal force method (RF‑/STEEL Plasticity)?
- Is it possible to transfer properties, such as the cross-section, or the surface thickness as well as the material of a surface, of an existing element to a new element?
- I would like to calculate and design "temporary structures." What do I need for this?
- Are the Dlubal Software programs suitable for the analysis and design of hydraulic steel structures?
- I would like to perform a stability analysis of the upper flange in a long truss. What is the best way to proceed?
- How does the activation of the precamber imperfection work?
- Are the models and presentations from Info Day 2020 freely available, and can you send them to me?
- I perform a stability analysis of a beam for lateral-torsional buckling. Why is the modified reduction factor χLT,mod used in the design according to DIN EN 1993‑1‑1, 6.3.3 Method 2? Is it possible to deactivate this?
- I need to define different types of lateral intermediate restrains for a single element in RF-/STEEL EC3. Is this possible?
- I compare the flexural buckling design according to the equivalent member method and the internal forces according to the linear static analysis with the stress calculation according to the second-order analysis including imperfections. The differences are very large. What is the reason?
