The composite steel-concrete system has been used in various major projects motivating the development of an efficient composite floor system using cold-formed steel sections with web corrugations. The system was based on previous investigations that involved the development of steel deck prototypes using various types of interlocking mechanisms in the concrete to steel deck interface. An ideal section evaluation was made to determine an efficient steel profile that presented a good mechanical adherence to the concrete interface while keeping a ductile behavior. Variables like weight, height, thickness and yield stress amongst others were investigated. An experimental program consisting of a full-scale composite slab test was executed to validate the proposed composite cold-formed system.
