I have been using RFEM 6 for my steel design projects in Italy and abroad for a few years now, and it has become indispensable! Geometric modeling, always fast and precise, is easy and convenient due to the internal (CAD) tools. Any type of a structure, from the simplest (beam elements) to the most complex geometries with shell elements, can be modeled with ease; BIM is excellent with other software. Editing is also easy, and if you make changes or revisions to the design, it takes a moment to implement them. The software includes several design standards, is flexible in use, clear, complete with all types of structural analysis, both static and dynamic, precise and reliable. In my opinion, it excels in nonlinearities when both entering the data and performing the nonlinear calculation; the mesh quality is excellent. The post-processing is very complex and the results are always clear, reliable, and easy to check and interpret. It always gives me freedom in my design preferences and assists me with all of them. When I compare myself with colleagues who use other software, frankly, it is impossible to do better. It simply does things that other software does not, and does them in an easy way. The support provided by the Italian team has always been up to the highest standards and has only improved over the years. Thanks and congratulations!
RFEM – Indispensable Software!
Do you have any questions?
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.
In RFEM, the oriented strand board (OSB) material is available for the USA and Canada. The material parameters are taken from the "Panel Design Specification manual".
The "Bracing in Cells" function allows you to generate diagonal bracing with just a few clicks. You can find this feature under Tools → Generate Model – Members → Bracing in Cells.
In RFEM and RSTAB, you can visualize the flow field quantities of pressure, velocity, turbulence kinetic energy, and turbulence dissipation rate for the wind simulation.
The clipping planes are aligned with the respective wind direction.
In RFEM, you can generate surfaces from members with the library cross-sections as well as from the members with the RSECTION cross-section.
