With the Steel Design add-on, you can design steel components for fire situations using the simple design methods according to Eurocode 3. The component temperature at the time of the design check can be determined automatically according to the temperature-time curves specified in the standard. In addition to considering fire protection cladding, you can take into account the advantageous properties of hot-dip galvanization.

This article explores the importance of considering joint-structure interaction in modeling and design and how to do it in RFEM 6 and RSTAB 9.

This article provides a comprehensive overview of essential seismic analysis methods, explaining their principles and applications, as well as the scenarios in which they are most effective

When 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.
