Ultimate Limit

The use of concrete foundations on a natural subgrade of brick buildings with a spatial cross-wall structural system can lead to its ultimate limit and elastoplastic states along the perimeter and, as a consequence, unallowable soil deformation and movement. The paper proposes to eliminate ultimate limit and elastoplastic states along the perimeter of concrete piles through the replacement of the foundation slab by the combined piled-raft foundation. The finite element modeling of the stress-strain state of the concrete foundation and the building superstructure of the base-foundation-building system is performed in the MicroFe software package allowing to appropriately estimate this state in real geotechnical conditions. According to calculations, 46 % of the vertical load of the building is taken by concrete piles along the perimeter, and 54 % of this load is taken by the concrete foundation. The use of the combined piled-raft foundation allows eliminating unallowable soil deformation of the foundation and provides meeting the standard requirements.
