How can I design a foundation for lifting loads?

Answer

The design of lifting loads is performed in RF‑/FOUNDATION Pro under the name of "Uplift limit state design."

In this case, it means not only the uplift of the foundation with regarg to the groundwater level, but also the presence of the lifting or negative support forces.

The uplift limit state design can be activated in "Details" of the add-on module or it is activated by default when creating a new design case (see Figure 01).

If the dimensions of the foundation should be designed, the program increases the foundation dimensions iteratively until the uplift limit state design is fulfilled.
