BEHAVIOR OF STEEL-DECK-REINFORCED SLABS

Results and behavioral characteristics are presented for five full-scale two-way slabs tested to ultimate. The concrete slabs were reinforced with composite corrugated cold-formed steel decking. Three slabs contained supplementary reinforcing in the form of welded wire fabric. Nominal out-to-out plan dimensions of the slabs were 16 ft by 12 ft (4.88 m by 3.66 m). Four slabs had a nominal thickness of 4.5/8 in. (118 mm) and one a thickness of 5-1/2 in. (140 mm). All slabs were subjected to four summetrically placed concentrated loads (simulating a fork lift). Ultimate failure was a shear-bond action initiated by slippage between the steel deck and the concrete with the concrete moving outward parallel to the deck corrugations, resulting a end slip in the central regions of the slabs. The addition of the welded wire fabric influenced the behavioral characteristcis and the ultimate load-carrying capacity. Near ultimate, the load-carrying action of the slabs was characteristics of a one-way slab.
