Perform the fire resistance design with a reduced load-bearing capacity according to the component temperature determined automatically right at the design time. You can determine this automatically according to various temperature curves in the program (a standard temperature-time curve, an external fire curve, a hydrocarbon curve). For other types of temperature determination, it is also possible for you to manually specify the temperature to be applied in the design. You can determine this, for example, according to the parametric temperature-time curve from DIN EN 1991‑1‑2 or from a fire protection report.

In the Steel Design add-on, you can perform the stability and cross-section design checks of cold-formed sections according to EN 1993‑1‑3 in compliance with Sections 6.1.2 – 6.1.5 and 6.1.8 – 6.1.10.
Go to Explanatory VideoWhen performing a design according to EN 1993‑1‑3, it is possible to graphically display a mode shape for the distortional buckling of a cross-section, and for the RSECTION cross-sections.
The mode shape can also be output in RSECTION 1 for library cross-sections.
- Calculation of deflections and comparison with the normative or manually adjusted limit values
- Consideration of a precamber for the deflection analysis
- Different limit values are possible, depending on the design situation type
- Manual adjustment of reference lengths and segmentation by direction
- Calculation of deflections related to the initial structure or to the deformed structure
- Further detailed design checks depending on the selected design standard (for example, limitation of web breathing according to EN 1993‑2)
- Graphical result display integrated in RFEM/RSTAB; for example, the design ratio of a limit value, the deformation, or the sag
- Complete integration of the results into the RFEM/RSTAB printout report
In RFEM/RSTAB, you have the option to generate and then calculate the load or result combinations required for the serviceability limit state. You can select these design situations for the deflection analysis in the Steel Design add-on. The calculated deformation values are determined accordingly at each location of a member, depending on the specified precamber and reference system. Finaly, you can compare these deformation values with the limit values.
Did you know? You can specify the deformation limit value individually for each structural component in Serviceability Configuration. Define the maximum deformation depending on the reference length as the allowable limit value. By defining design supports, you can segment the components in order to determine the corresponding reference length automatically for each design direction.
Based on the position of the assigned design supports, the distinction between beams and cantilevers is made automatically so the limit value can be determined accordingly.
