Of course, this changes when the groundwater table reaches the structure, but that’s about watertightness, not just...

    Differential soil settlement

    Finite element modeling is better than using the Winkler model, which simplifies multiple soil layers — no matter how homogeneous they may be — into a single value. Additionally, in the Winkler approach, the springs do not interact directly with each other. A point load applied at one node only...

    Differential soil settlement

    Greetings! It is likely that your design software has introduced soil-structure interaction through winkler springs or similar. However, it is important to interpret these additional stresses with caution. If the beams and slabs showing significant additional stresses are those located at the...
