Composite Steel Concrete Beam Floor Systems

This study deals with compartment fire experiments on 12 8 m long composite floor beams with various end support conditions.

Composite steel concrete beam floor systems.

As it was told earlier the composite flooring system has been designed at first for non residential building. The scope of this review paper is to give an overview of current developments in steel concrete composite scc beams and flooring systems as well as to clarify and support future research directions and trends which the industry will take in the coming years. A widespread composite flooring system is a concrete slab resting upon downstand steel i beams see figure 1 2. Composite floors i version ii 23 page composite floors i 1 0 introduction traditional steel concrete composite floors consist of rolled or built up structural steel beams and cast in situ concrete floors connected together using shear connectors in such a manner that they would act monolithically fig 1.

Each specimen was constructed as a partially composite beam consisting of a lightweight concrete slab cast on 76 mm 3 in deep ribbed steel decking and a w18 35 steel beam acting compositely via 19 mm 3 4 in diameter steel headed stud anchors welded on the top flange. Collaboration of steel and concrete parts of the structure is provided by anchors welded on the upper flange of the i beam.
