Material stress-strain diagram based design method for cast in-situ floor slabs with external profiled steel sheetings as reinforcements

Abstract

This paper outlines research work carried out to establish a method of designing in situ cast floor slabs with profiled steel sheetings 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 sheetings 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.
