FOUNDATION
One of the main topics of interest in combined civil - geotechnical engineering is the foundation analysis of buildings. Especially when the geometrical configuration of piles is non-trivial, and the soil properties are complex, a FE calculation gives added value.
In the foundation calculation shown here, an existing high-rise building (height: 97 m) is partially demolished and then vertically (new height: 110) and
ground-area-wise (additional ground area: 300 m2) extended.
The extension has a piled raft foundation.
Actually, the whole building has one foundation now, since the old and the new part are connected.
The first figure 3D FE mesh; the calculation uses the hardsoil material model as available in Tochnog Professional.
The second figure shows the back-analyis of the settlements of the existing high-rise; yes, maximum measured settlement is 30.6 cm!.
