Abstract
Post-tensioned composite steel-concrete slabs represent an economical form of construction widely used in Australia for flooring systems. In particular, they consist of thin-walled profiled steel sheeting, post-tensioning strands and concrete.The particularity of this structural solution relies on the ability of the profiled steel sheeting to act as permanent formwork and, once the concrete has hardened, as external reinforcement. This paper presents the experimental results of six full-scale post-tensioned composite slabs, cast on Stramit Condeck HP® steel deck.The samples differed in their thicknesses (180mmand 225 mm), total lengths (7.2mand 8.65 m), the number of prestressing strands, and curing conditions. Time-dependent deformations are reported for the first few months after pouring up to the time of their ultimate tests, whose results are also presented. Concluding remarks are provided at the end of the paper.
