Is it possible to somehow verify the bending moment from the integration of contact stresses determined in RF-/FOUNDATION Pro?

Answer

This is possible over a detour in RFEM.


The soil pressure, from which the bending moment is determined for the design using integration, can be applied as an 'external load' in an RFEM initial model.

Compressive Stress Distribution in RF-/FOUNDATION Pro

This compressive stress can be applied to an equivalent system in RFEM as a 'Free Surface Load'.

In this case, the equivalent system is a rigid surface. The size of the surface depends on the position of the design section set in RF-/FOUNDATION Pro. In this case, it is necessary to set 'In Column Center'.

With this equivalent system, it is possible to recalculate the 'Moment from Compression Stress Distribution' determined in RF-/FOUNDATION Pro.

You can download the example described above using the link below and open it in RFEM 5.
