Abstract:
Composite steel-concrete beam systems are widely used in floor systems of steel framed multi-storey buildings. Current trend in construction is to produce column free floors and to specify longer beams capable of spanning between the building core to the edge columns.

Composite steel-concrete floor beams consist of a steel girder interconnected to a solid or composite slab by means of shear connectors. This combination leads to enhanced strength and stiffness when compared to the contribution of their components acting separately, and represent a competitive structural solution in many civil engineering applications, such bridges and buildings.

The aim of this research project is to provide insight into the response of composite beams formed with deep trapezoidal steel deck and to evaluate how this influences both its service and ultimate response. A numerical model is currently under development to predict the complex interaction between the steel joist, shear connectors, steel deck and concrete slab and to evaluate how this affects the global response. Experimental work will be carried out to validate some of the numerical results.
