Frequently Asked Questions (FAQ)

AnswerYes, it is possible.You can enter a pile foundation to a structural model in RFEM.Thus, the effects of the foundation stiffness on the actual structure can be simulated very well.However, please note that Dlubal Software currently provides no solutions for the design of pile foundations.This also means that the pile resistance must be known to the user in advance. It cannot be calculated in RFEM, for example, by defining a soil structure.The piles can be designed as beams by using a circular cross-section, for example.The resistance of the piles can be modeled by entering a member elastic foundation or a nodal support at the pile end.Subsequently, the design of the beam can be performed in the RF‑CONCRETE Members add-on module. However, please note that RF‑CONCRETE Members only covers the standards relevant for the structures above ground level. That is, for example, DIN EN 1992‑1‑1.
In the example, I have created a model with a 0.5 m wide member.
Assuming a foundation of 200kN / m³, the translational spring corresponds to 200kN / m³ = 100kN / m² * 1 / 0.5m.
If you want to support the member with springs, multiply the foundation with the member width (100kN / m³).
If you now want to additionally consider the skin friction, you have to include the circumference in the calculation (see Solid, for example).
AnswerFor the pile tip resistance, the bedding must be multiplied by the cross-sectional area (see Figure 1).For skin friction, the bedding must be multiplied by the circumference of the cross section (see Figure 2).

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. ”
