摘要

Developments in shallow floor structures over the last ten years have produced systems in which composite behaviour is frequently encountered due to various bond interfaces between concrete and steel components. Depending on the types of structural elements used in the floor, this composite action may be defined as either intentional or unintentional. Both forms have an influence on structural behaviour and on design decisions, and this paper discusses the important features to bear in mind when considering composite interaction, its rating in the serviceability state and possible deterioration when entering the plastic behaviour and ultimate limit states. A special case in shallow floor construction is the integration of hollow core slabs with beams, and these problems are also discussed. The phenomena observed are explained on the basis of the general flexural theory of composite structures and numerical studies carried out by the finite element method. An overview of development during the last ten years is given.
