Smart Decision for 3D Modeling of Steel Structures Using RFEM 6
After a detailed evaluation of the solutions available on the market, we have decided on RFEM by Dlubal for the structural analysis and design of our three-dimensional steel structures.
The software complies with the Eurocode standards, has an intuitive user interface, and exceptional transparency and display of input data and results. The technical support proved to be of the highest quality, combining patience, competence, and reactivity, which reinforced our confidence in this choice.

Industrial Filter Device
The project for designing a filter/dryer device, including agitator, required a complete stress and deformation analysis in RFEM. What made the structure so special was its complex modeling with 1,424 surfaces, 158 solids, and 425 members.

In order to be able to carry out a pushover analysis, it is necessary to transform the determined capacity curve into a simplified form. The N2 method is described in Eurocode EN 1998. This article should help to explain what a bilinearization according to the N2 method involves.
Both the determination of natural vibrations and the response spectrum analysis are always performed on a linear system. If nonlinearities exist in the system, they are linearized and thus not taken into account. They are caused by, for example, tension members, nonlinear supports, or nonlinear hinges. This article shows how you can handle them in a dynamic analysis.
If the geometry of a surface for which you must remove some of the existing boundary lines changes subsequently, you do not need to redefine the surface.
RF-MOVE Surfaces facilitates the generation of load cases from different positions of moving loads. Based on the load positions of the moving load, the program generates separate load cases for RFEM 5. Optionally, an enveloping result combination of all load positions is created.
The design of cold-formed steel members according to the AISI S100-16 / CSA S136-16 is available in RFEM 6. Design can be accessed by selecting “AISC 360” or “CSA S16” as the standard in the Steel Design Add-on. “AISI S100” or “CSA S136” is then automatically selected for the cold-formed design.
RFEM applies the Direct Strength Method (DSM) to calculate the elastic buckling load of the member. The Direct Strength Method offers two types of solutions, numerical (Finite Strip Method) and analytical (Specification). The FSM signature curve and buckling shapes can be viewed under Sections.
In SHAPE-THIN 8, the effective cross-section of stiffened buckling panels can be calculated according to EN 1993-1-5, Cl. 4.5.
The critical buckling stress is calculated according to EN 1993-1-5, Annex A.1 for buckling panels with at least 3 longitudinal stiffeners, or according to EN 1993-1-5, Annex A.2 for buckling panels with one or two stiffeners in the compression zone. The design for torsional buckling safety is also performed.
In the Snow Load Wizard, you can optionally consider snow overhang and snow guard when generating snow loads according to Eurocode.
The Construction Stages Analysis (CSA) add-on allows you to modify the object and design properties of members, surfaces, and so on, in the individual construction stages.
Why is it not possible to select the plate that I want to adjust in the “Plate Cut” and “Plate Editor” components?
Is it possible to consider the eccentricity of unsymmetrical line welds for the stress analysis in RFEM 6?
How can I reduce the calculation time for members with a nonlinear material model in RFEM 6 and RSTAB 9?
Why does the integration/support of my building in the ground below the ground level not work?
How can I create a contact solid between two surfaces in RFEM?
I want to create a mapped mesh for a circular hole plate. Is it possible to generate such a meshing in RFEM?
