COMPENDIUM OF ISU RESEARCH CONDUCTED ON COLD-FORMED STEEL-DECK-REINFORCED SLAB SYSTEMS

An extensive theoretical and experimental research program on steel-deck-reinforced floor systems has been conducted at Iowa State University. A total of 353 full-scale tests were performed on the following types of specimens: pushout, single span slab elements with steel deck corrugations oriented parallel to span length, slab elements with steel duck corrugations oriented transverse to span length, slab elements continuous over two or three spans, slab elements subjected to repeated loading, slab elements constructed with variable supplementary reinforcement, slab elements constructed with noncomposite deck having various surface coatings, full-size two-way floor slabs simply supported on four edges, slab elements with various shoring conditions, and slab elements subjected to uniform versus concentrated loading. The purpose of the above tests was to investigate typical behavioral characteristics and modes of failure. The principal failure mode was fouud to be that of shear-bond, for which design equations were formulated to predict the capacity. The primary objective of the research program was to develop information leading to specifications governing the application, use, and design of concrete slabs reinforced with cold-formed steel decking.
