New Concept of Slimfloor with Prestressed Composite Beams

An original concept of Slimfloor structure made of hollow core slabs with structural concrete topping and post-tensioned delta-shaped beams is given in the paper. The technological assumptions and the results of computational analysis for this solution are also discussed. Multi-span continuous prestressed beam can significantly increase length of the span of the Slimfloor ceiling and at the same time keeps its primary asset - almost flat bottom surface - creating the ideal solution for the demanding projects.
