Abstract:
Industrial concrete floors, constructed either as slabs-on-ground or as pile-supported slabs, are not considered as load-carrying structures. When designing such floors in Sweden, engineers can choose between two design methods with different safety levels. Research is needed to understand why the less conservative of the two methods has led to many successful floors.
