Design Method For Cast In-Situ Floor Slabd With External Profiled Steel Deck As Reinforcement

Abstract

This paper outlines research work carried out to establish a method of designing in situ cast floor slabs with external profiled steel sheeting reinforcements based on the use of “stress-strain” material diagrams. It details out experimental and analytical work carried out to investigating the effects of selected bonding devices on the concrete/profiled steel sheeting slip resistance, in which the effects of bonding embossment’s depth and the concrete/profiled steel sheeting bonding length are considered. A model is developed to simulate load-deformation characteristics of profiled steel sheeting reinforced in in-situ-cast concrete floor slabs. Comparisons are presented between design solutions obtained by applying the worked out designing method and experimental results.
