Slim-Floor Beams: Design Criteria and Structural Behaviour

Document Type: Proceeding Paper

Part of: Composite Construction in Steel and Concrete II


Partially concrete-encased steel beams are mostly employed due to their natural resistance to fire, but there may also be other reasons, e.g. to obtain smaller depths of construction. The aspect slim is used to emphasize this. Quite short erection times are required for the floorings if prefabricated decking units, e.g. hollow-core slabs are employed. This paper describes the design requirements needed to obtain a sound solution for a flooring system in which the interaction between the beam and the decking units may affect the load resistance of the flooring.
