Frequently Asked Questions (FAQ)
Customer Support 24/7
AnswerThe analysis of a rigid column footing is performed according to EN 1993-1-8 in the RF-/JOINTS Steel - Column Base add-on module. The standard only provides for simple bending in the design format. The design can be performed for compression only, tension, simple bending, or a combination of bending and tension, or bending and compression. If the note is confirmed with 'Yes', the add-on module performs all designs neglecting the unsupported internal force Mz.
AnswerIn the current set of rules, fasteners or connections are always designed in one plane only. The reason for this is that the designs for shear etc. can only be analyzed in the 2D plane. The design of bearing, for example, is not possible for a failure from the plane.Since internal forces in vy and vz can always occur in a three-dimensional calculation, it has been proven in practice to allow a small proportion of internal forces in secondary direction and not fully utilize the connection. However, if the ratio of shear force in secondary direction is too high, a detailed analysis with an FE simulation might potentially be necessary.
Designs in our module RF-/JOINTS Steel - Rigid are based on the assumptions and regulations of the standard EN 1993‑1‑8. Here, bending from the main beam plane is not considered.
In RFEM, it is possible to model any rigid joint. All internal forces can then be taken into account.

Wind Simulation & Wind Load Generation
With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
“Thank you for the valuable information.
I would like to pay a compliment to your support team. I am always impressed how quickly and professionally the questions are answered. I have used a lot of software with a support contract in the field of structural analysis, but your support is by far the best. ”
