RF-SOILIN Add-on Module for RFEM
Determination of Elastic Foundation Coefficients by Means of Soil Data
The RF-SOILIN add‑on module determines the elastic foundation by means of soil layers. A realistic determination of soil conditions is important for the structural analysis of buildings.
Designs are performed according to the following standards:
- EN 1997‑1:2004
- DIN 4019‑1:1979‑04
- CSN 73 1001
- Code independent (analysis only)
- Realistic representation of interaction between building and soil
- Extensible library of soil properties
- Consideration of several soil samples (probes) at different locations, even outside the building
- Consideration of groundwater level as well as side effects due to excavation and lowest soil layer being solid
- Calculation of elastic foundation coefficients
- Determination and graphical display of stress diagrams and settlements in grid points
The definition of soil layers is performed in a clearly arranged input window. An extensible library facilitates the selection of soil properties.
The elasticity can be defined either by the stiffness modulus or the modulus of elasticity and the Poisson's ratio. It is possible to define any number of soil layers. You can assign the layers to the building graphically or by entering the relevant coordinates.
Elastic foundation coefficients are calculated according to the non-linear iterative method. The module determines elastic foundation coefficients for each individual element. They are dependent on the deformation.
The calculated stresses and settlements are displayed in result windows. In addition, it is possible to evaluate the results graphically. The graphic displays the position and the layer arrangement of the soil samples to clarify the results.
The final result window shows the elastic foundation coefficients. Graphical evaluation is possible as well.
Settlement within a structural system can also affect the surrounding structures.
- 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?
- When designing a foundation slab under a circular tank, the contact stress in the middle of the surface is not displayed. What could be the reason?
- Why do I obtain such high contact stresses at the foundation edges of my floor slab?
- What happens if I activate the "Soil failure" function in RF‑SOILIN?
- Can I combine the nonlinear calculation in RF‑CONCRETE NL with the determination of foundation coefficients in RF‑SOILIN?
- How can I change the Standard / National Annex set for the design in the add-on modules and stand-alone programs?
- Is there a way 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?
- How can I specify different moduli of subgrade reaction for a large floor slab?
- Red values are displayed in the intermediate results of RF‑SOILIN. Why?
