Considering Adjacent Settlement for Separated Floor Slabs With RF-SOILIN
Tips & Tricks
Settlement within a structural system can also affect surrounding structures. The adjacent settlement of separated slabs can be considered with RF-SOILIN using a small trick.
If there is no connection between the adjacent floor slabs, then the settlement of one slab has no effect on the other slab.
Since this assumption is incorrect for the calculation of settlements or is often on the unsafe side, it is usually better to consider the adjacent settlement. The easiest way is to try to connect the surfaces by a foundation overlap with negligible stiffness. Entering a foundation overlap around the buildings' floor slabs also allows you to better estimate the influence of the settlement on the surrounding area. This way you can manually increase it iteratively until the subsidence basin is completely enclosed by the foundation overlap.
Due to the additional surfaces, the settlements are also transferred to other adjoining building parts, and the total deformation of all buildings is represented a bit more realistically.
This approach is of course not limited to the RF-SOILIN add-on module, but can also be applied to other foundation types.

If I do not specify any basic reinforcement in RF-CONCRETE Surfaces, I get the value X as additionally required reinforcement. If I enter this value X as the existing basic reinforcement, I correctly do not get any additional required reinforcement.
However, if I enter a lower value than the determined required total reinforcement as the basic reinforcement, the additionally required reinforcement is increased in such a way that the originally required reinforcement content is exceeded. Why?
