Structural optimization of a composite steel and concrete connection through FE analysis and testing

The increasing ratio between labour cost and the cost of construction materials is urging for the development of construction techniques requiring the smallest number of skilled workers and the optimization of building schedule in order to minimize the overall building time. Composite decks and floors are becoming increasingly widespread due to their structural effectiveness that allows for the optimization of the mechanical properties of the coupled materials and for the possibility of achieving a simplified detailing with a limited number of structural elements involved in the structural response.

In the paper, a newly developed moment resisting connection between a centrifuged high strength concrete pre-fabricated column and a composite steel and concrete beam will be presented. The connection proposed allows for a sustainable construction process based on modern construction technoligies which are suitable for creating improved structures for buildings in urban areas.
