The Effective Sections extension is fully integrated in RSECTION. Thus, there is no second program and window chaos that make your work difficult. Therefore, all input options of RSECTION are available to you. You only need to specify the standard group in the Base data, according to which the effective cross-section is to be determined. After importing the section into the main program RFEM or RSTAB, it is available like a library section for design in the Steel Design. Sounds good, doesn't it?

The ASCE 7-22 Standard [1], Sect. 12.9.1.6 specifies when P-delta effects should be considered when running a modal response spectrum analysis for seismic design. In the NBC 2020 [2], Sent. 4.1.8.3.8.c gives only a short requirement that sway effects due to the interaction of gravity loads with the deformed structure should be considered. Therefore, there may be situations where second-order effects, also known as P-delta, must be considered when carrying out a seismic analysis.
This article presents the basic concepts in structural dynamics and their role in the seismic design of structures. Great emphasis is given to explaining the technical aspects in an understandable way, so that readers without deep technical knowledge can gain an insight into the subject.
In this article, the calculation of a timber panel wall with the beam panel thickness type is compared with a manual calculation.
The fatigue design according to EN 1992-1-1 must be performed for the structural components subjected to large stress ranges and/or many load changes. In this case, the design checks for the concrete and the reinforcement are performed separately. There are two alternative design methods available.
- 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 1993-1-3
- 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, stability, and serviceability limit state design checks of RSECTION cross-sections of Class 4 according to EN 1993‑1‑1 or EN 1999‑1‑1 in the Steel Design or Aluminum Design add-ons
- Cross-section checks for cold-formed RSECTION cross-sections according to EN 1993‑1‑3 in the Steel Design add-on
- Available for all National Annexes integrated in the Steel Design add-on

Are you just waiting for your results after the design? The design results are displayed in the usual way in the Steel Design add-on. In the corresponding output tables, you can find the classification, the effective section properties, and the design check, among other things. The stresses are displayed to you graphically on the effective section as well as on the gross section.
Use the "Independent mesh preferred" option in the FE mesh settings to create an independent FE mesh for the integrated objects. This allows you to generate a significantly more detailed and precise FE mesh for individual objects that are integrated into one another.
The performance when starting the programs or working in the program has become noticeably worse. What could be the cause of this?
Is it possible to influence the transverse distribution of a load in the case of the Isotropic | Masonry | Plastic material model?
What is the effect of the "Independent FE Mesh Ppreferred" option in the mesh settings?
