Abstract: Concrete slabs on steel deck are the most common type of floor system in use today. This system of construction is particularly advantageous when ultimate strength design (LRFD) is used. Because substantially more slender floors are possible, there is some concern that serviceability criteria are not being adequately addressed. This paper reviews current deflection serviceability criteria and describes some experimental work aimed at clarifying the importance of creep, shrinkage, and end restraint in calculating floor deflections.
