RESUMO

This work presents an investigation of an innovative composite slab system made of a steel deck and a styrofoam plate, side by side, filled with reinforced concrete. The objective of the present study was the development of an efficient composite slab system that is easy to manufacture, erect and also economic.The investigation started with a parametric design study of the steel deck profile.When an optimum steel deck profile was established the investigation proceeded with a series of full-scale- experiments. The tests enable the establishment of the ultimate and serviceability limit states associated with the investigated system.Another aim of the experiments was to investigate the concrete versus steel deck connection. Solutions using only the natural concrete versus steel adherence and others utilising shear connectors made of self-drilling bolts in the steel deck were considered. Finally current steel design codes were used to compare the experimental results and access the accuracy of the composite slab system In this paper a composite slab system developed for low-cost building construction is presented. Results and conclusions from a theoretical and experimental study were summarized below the work. Finally these composite slab systems can be implemented in large scale construction, just by the development of portable rolling equipment that can produce very long and continuous profiles, as required by the construction teamwork.
