First Steps with RFEM
Description
With the rapid development of the Chinese economy, more and more large commercial complexes are being built and there is an increasing demand for escalators with great heights, large spans, and without intermediate supports.

Creating Lateral Intermediate Supports
In RF-/STEEL EC3, the Window 1.4 Lateral Intermediate Supports offers you the option to define lateral intermediate supports at individual members. These supports are created from connected purlins and horizontal beams, for example, and increase the resistance against lateral-torsional buckling. Lateral intermediate supports can be entered either with a relative or an absolute distance.
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.

- I am trying to manually check the deformations from the CRANEWAY add-on module. However, I obtain great deviations. How to explain the differences?
- What should be considered when using a failure of columns under tension in the RF‑/DYNAM Pro – Equivalent Loads add-on module?
- Why is there no stability analysis displayed in the results despite the activation of the stability analysis in RF‑/STEEL EC3?
- How can I model and design a crane runway girder with Dlubal Software?
