Strength and Stability
The "Steel Design" add-on allows you to perform the cross-section resistance design and stability analysis of steel member structures in the ultimate limit state. The input and result evaluation are completely integrated in the user interface of the structural FEA software RFEM and the frame & truss analysis software RSTAB.
- A wide range of available sections, such as rolled I-sections; channel sections; T-sections; angles; rectangular and circular hollow sections; round bars; symmetrical and asymmetrical, parametric I-, T-, and angle sections; built-up cross-sections (suitability for design depends on the selected standard)
- Design of general RSECTION cross-sections (depending on the design formats available in the respective standard); for example, equivalent stress design
- Design of tapered members (design method depending on the standard)
- Possible adjustment of the essential design factors and standard parameters
- Flexibility due to detailed setting options for basis and extent of calculations
- Fast and clear results output for an immediate overview of the result distribution after the design
- Detailed output of the design results and essential formulas (comprehensible and verifiable result path)
- Numerical results clearly arranged in tables and graphical display of the results in the model
- Integration of the output into the RFEM/RSTAB printout report

Designed with Steel Design for RFEM 6
Stability Analysis
Comprehensive calculation of all required coefficients, such as factors for taking into account the moment distribution or interaction factors.
Alternative consideration of all effects for the stability analysis already during the determination of internal forces in RFEM/RSTAB (second-order analysis, imperfections, stiffness reduction, if necessary in combination with the Torsional Warping add-on).

Fantastic and Professional Support
I would just like to send a quick note to wish everyone at Dlubal well, in particular I would like to say thank you for the fantastic, thorough and professional support you provide.
Powerful, Easy to Use, Easy to Learn…
We adopted Dlubal in our work and haven't looked back. Powerful, easy to use, easy to learn, with mercifully simple output (once set up).

In this article, we will explore the various types of stability failures, delving into their key features, causes, and how they manifest in different structural systems.
According to AISC Design Guide 9 Section 4.1 [1], the following torsional stresses must be considered for open cross-sections subjected to warping:
This article will show you how to model stiffened tubular joints in the Steel Joints Add-on.
Utilizing the Steel Design Add-on, steel design is possible according to the AISC 360-22 standard. The following article will compare the result output when calculating lateral torsional buckling according to Chapter F vs. an Eigenvalue Analysis.
It is now possible to keep the results of the steel, steel joint, aluminum, and timber design despite changing the design properties and settings (see the setting in the image). The results are thus not deleted, but marked as invalid.
When restarting the design, only the invalid design results are updated. If objects are subsequently added to the design, they are additionally designed when restarting the design, while the previously calculated results remain valid.
The seismic design result is categorized into two sections: member requirements and connection requirements.
The "Seismic Requirements" include the Required Flexural Strength and the Required Shear Strength of the beam-to-column connection for moment frames. They are listed in the ‘Moment Frame Connection by Member’ tab. For braced frames, the Required Connection Tensile Strength and the Required Connection Compressive Strength of the brace are listed in the ‘Brace Connection by Member’ tab.
The program provides the performed design checks in tables. The design check details clearly display the formulas and references to the standard.
In the Steel Design add-on, you can perform the seismic design of steel members according to AISC 341‑16.
Five SFRS types (Seismic Force-Resisting Systems) are available for this.
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.

I am using the Steel Design add-on. Can I define the cross-section class manually?
The lateral torsional buckling (LTB) check looks missing in the Steel Design. What could be the reason?
How can I perform member design by case for different settings in the design configuration?
How can I design single-angle compression member according to AISC Section E5?
Is it possible to use the General Method according to EN 1993‑1‑1, 6.3.4 to design structural components with an asymmetric cross-section in the Steel Design add-on for RFEM 6 or RSTAB 9?
Can I use design cases in RFEM 6 in the same way as in RFEM 5?
