Effective Sections
Determination of Effective Sections
Advantages
Effective Sections is an extension of RSECTION. It determines the effective sections according to the following standards:
-
EN 1993-1-5 - EN 1993-1-3
- EN 1999-1-1
1
Features
- Available for general thin-walled RSECTION cross-sections
- Classification according to
- EN 1993-1-1
- EN 1993-1-4
- EN 1999-1-1
- Determination of the effective section according to
- EN 1993-1-5
- EN 1999-1-1
- Consideration of the effects of distortional buckling of cold-formed sections via eigenvalue method
- Determination of the stresses on the effective section and gross section
- Cross-section design, stability analysis, and serviceability limit state design for
RSECTION cross-sections of Class 4 according to EN 1993‑1‑1 in the Steel Design add-on - Available for all National Annexes integrated in the Steel Design add-on

Input
Effective Sections is fully integrated in RSECTION, so all input options of RSECTION are available. In the base data, you only have to specify the standard group according to which the effective section is determined. After importing the section into the main program RFEM or RSTAB, it is available for design in the Steel Design add-on like a library section.

Results
The design results are displayed in the usual way in the Steel Design add-on. The corresponding output tables show, among other things, the classification, the effective section properties, and the design check. The stresses are displayed graphically on the effective section as well as on the gross section.

Member Transverse Stiffeners in RFEM 6 and RSTAB 9
This article shows you how to define different types of member transverse stiffeners in RFEM 6 and RSTAB 9. It also shows you how to consider them in the design as well as the calculation of members with 7 degrees of freedom.

Connection of Rectangular Hollow Sections
Rectangular cross-sections can be connected directly to each other or to other cross-sections using welds. Furthermore, it is possible to connect rectangular cross-sections to other structural components using other components, such as end plates.
