This paper presents the structural behavior of composite concrete slabs with CRIL DECKSPANTM (Colour Roof India Limited (CRIL), Mumbai, INDIA) type profiled steel decking by experimental and analytical studies. The slab is created by composite interaction between the concrete and steel deck with embossments to improve their shear bond characteristics. However, it fails under longitudinal shear bond due to the complicated phenomenon of shear behavior. Therefore, an experimental full-size tests has been carried out to investigate the shear bond strength under bending test in accordance to Eurocode 4 - Part 1.1. Eighteen specimens are split into six sets of three specimens each in which all sets are tested for different shear span lengths under static and cyclic loadings on simply supported slabs. The longitudinal shear bond strength between the concrete and steel deck is evaluated analytically using m-k and partial shear connection (PSC) methods and compared the values. The experimental results is verified and compared with the results of both m-k and PSC methods. Comparison of experimental and analytical results of the load-carrying capacity of composite slabs revealed that agreements between these values are sufficiently good. As a result, m-k method proved to be more conservative than PSC method.read more

Longitudinal shear resistance of composite slabs containing crumb rubber in concrete toppings
TL;DR: In this article, the authors investigated the behavior and longitudinal shear capacity of metal deck composite slabs with the inclusion of crumb rubber in the concrete toppings and found that the ability of the slabs to act compositely is governed by the shear interaction between the concrete topping and the profiled steel deck.

Composite Steel and Concrete Structural Members: Fundamental Behaviour
TL;DR: In this article, the analysis and behaviour of composite structural members that are made by joining a steel component to a concrete component is discussed, so that engineers develop a feel for the behaviour of the structure, often missing when design is based solely by using codes of practice or by the direct application of prescribed equations.
