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