SOFiSTiK Online Training Soil Structure Interaction with the Half Space Method

One of the most accurate methods to model soil is using 3D volumetric finite elements. This, however, requires a vast number of soil elements. And in many cases, it exceeds the number of structural elements, which is the structural engineer’s main interest.
In this online training, you will learn about the Half-Space theory and how to overcome problems when modelling soil as 3D volumetric finite elements or even considering the Winkler assumption.
With the Half-Space programme module, a sub-structuring technique is adopted. The structure will be represented using standard finite elements, while the soil will be modelled semi-analytically using the half-space theory.
