The chosen form of any substructure is entirely dependent on what the site investigations reveal. It is typically up to the structural engineer, with the aid of geotechnical engineers and specialists, to determine the extent of this investigation and interpret its results.
Dead loads (permanent actions) are defined as the weight of static materials contained with a structure. This includes the self weight of the structure as well as the fixed materials it is supporting.
When designing foundations (from a simple pad footing to a pile cap) there is a need to determine the soil's bearing capacity. This note explains the principles of how this is determined, and how it impacts on foundation design.
