Structural optimization of a composite steel and concrete connectionthrough FE analysis and testing

摘要

The increasing ratio between labour cost and the cost of construction materials is urging for thedevelopment of construction techniques requiring the smallest number of skilled workers and theoptimization of building schedule in order to minimize the overall building time. Composite decksand floors are becoming increasingly widespread due to their structural effectiveness that allows forthe optimization of the mechanical properties of the coupled materials and for the possibility ofachieving a simplified detailing with a limited number of structural elements involved in thestructural response.In the paper, a newly developed moment resisting connection between a centrifuged high strengthconcrete pre-fabricated column and a composite steel and concrete beam will be presented. Theconnection proposed allows for a sustainable construction process based on modern constructiontechnoligies which are suitable for creating improved structures for buildings in urban areas.
