Analysis Software for Soil-Structure Interaction
The structural engineering FEA software RFEM is the basis of a modular software system. The main program RFEM is used to define the model, materials, and loads of planar and spatial structural systems consisting of plates, walls, shells and members.
The program also allows you to create combined structural models as well as to model solid and contact elements.
In RFEM, it is possible to consider different soil models, such as:
- Subgrade reaction modulus method
- Modified subgrade reaction modulus method
- Modified two-parametric soil models (with foundation overlaps or additional springs)
- Stiffness modulus method (RF-SOILIN)
- 3D half-space analysis
We especially recommend to apply the stiffness modulus method using RF-SOILIN as the subgrade reaction modulus is determined interdependently with the load. In addition, you can define different soil layers in different areas. Thus, the soil structure is represented in a realistic way.
The structural analysis software provided by Dlubal can be seamlessly integrated into the Building Information Modeling (BIM) process. A variety of interfaces allows you to exchange data from digital building models with RFEM or RSTAB.

A foundation is usually created in RFEM using the subgrade reaction modulus method. The reason for this is the relatively easy and straightforward manageability. Also, no iterative calculations are necessary and the computing time is relatively small. The subgrade reaction means that, for example, a foundation plate is loaded flat elastically.

RFEM and RSTAB models can be saved as 3D glTF models (*.glb and *.glTF formats). View the models in 3D in detail with a 3D viewer from Google or Baylon. Take your VR glasses, such as Oculus, to "walk" through the structure.
- For the settlement calculation in the RF‑SOILIN add-on module, the specific weight gamma and gamma,sat are required for the soil. What do I need the value gamma,sat for, and how is it assumed in the calculation?
- Is there a way how to easily prevent RF‑SOILIN from recalculating the foundation every time the load in the governing load case is changed?
- Can I also use RF‑SOILIN to calculate foundation bodies at different foundation heights in a model?
- Why do I obtain such high contact stresses at the foundation edges of my floor slab?
- How do I define temperature loads on a composite beam?
How can I apply concentrated loads to a curved surface?
Why are my steel members not being designed for stability in RF-STEEL AISC?
- Can I define surfaces with any number of boundary lines?
- Can the properties, such as B. the cross -section or the surface thickness as well as the material of a surface of an existing element for a new element?
I created a very simple model to check the manual calculation. I can't get to the expected results. Could you give me an advice please?
