Powerful Structural Analysis Software RFEM 6
RFEM 6 has a rich library of cross-section and materials, including special point-line surface attributes, which can realistically simulate a variety of complex force situations. The program is powerful in nonlinearity and form finding, which can reduce the difficulty of engineers to start. The pre-processing can be linked to the Grasshopper parameterization platform, which is convenient for spatial structural modeling as well as iterative calculations. And the post-processing interface is intuitive and user friendly, with strong extensibility and more options.

In this article, you will learn how to model and design cable structures in RFEM 6 or RSTAB 9.
This article describes and explains the influence of bending stiffness of cables on their internal forces. Furthermore, the text provides information on how this influence can be reduced.
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.
The data exchange between RFEM 6 and Allplan can be done using various file formats. This article describes the data exchange of a determined surface reinforcement using the ASF interface. This allows you to display the RFEM reinforcement values as level curves or colored reinforcement images in Allplan.
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.
In the "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.
In RFEM 6 and RSTAB 9, you have the option to enter "Visual Objects" as guide objects. You can import the file formats 3ds, stl, and obj.
These objects allow you to create a better reference to the dimensions.
- Design of five types of seismic force-resisting systems (SFRS) includes Special Moment Frame (SMF), Intermediate Moment Frame (IMF), Ordinary Moment Frame (OMF), Ordinary Concentrically Braced Frame (OCBF), and Special Concentrically Braced Frame (SCBF)
- Ductility check of the width-to thickness ratios for webs and flanges
- Calculation of the required strength and stiffness for stability bracing of beams
- Calculation of the maximum spacing for stability bracing of beams
- Calculation of the required strength at hinge locations for stability bracing of beams
- Calculation of the column required strength with the option to neglect all bending moments, shear, and torsion for overstrength limit state
- Design check of column and brace slenderness ratios
Is it possible to use the add-ons for RFEM 6 to design concrete solids?
I get a message saying that unpermitted manipulation with time has been detected. What can I do?
What calculation is carried out for the NDS Strength Configuration "Calculation of Torsion" options?
I still get an error message, although the WebService settings are activated in RFEM 6.
Can I display node coordinates in my model?
I get an error when importing an .xml file from SCIA to RFEM 6. How can I import SCIA files into RFEM 6?
