What is meant by Subgrade reaction modulus method?
The subgrade reaction method is a technique in structural engineering used for calculating foundations and base plates while considering the flexibility of the subsoil. It is based on the assumption that the soil settlement at each point is proportional to the normal stress acting on the soil at that point. The subgrade modulus describes the relationship between the normal stress and the resulting settlement.
Typical software functions in the area of "subgrade reaction method":
- Soil parameter input: Recording of soil characteristics such as stiffness modulus and density.
- Load case generation: Creation of various load scenarios for calculation.
- Subgrade modulus calculation: Automatic determination of the subgrade modulus based on soil properties.
- Settlement calculation: Computation of expected settlements under given loads.
- Stress distribution: Representation of stress distribution in the soil and foundation.
- Internal force calculation: Computation of moments and shear forces in the foundation slab.
- Visualization: Graphical representation of settlements and stress distributions.
- Optimization: Tools for optimizing foundation geometry based on calculation results.
