Steel-concrete composite bridge deck with steel sheeting is one of the deck slabs which showed some advantages over the conventional reinforced-concrete (RC) deck slabs. This study modelled and analysed these kinds of composite slabs comprising of steel sheeting and shear connectors which are filled by normal strength concrete. Finite element analysis (FEA) is applied for modelling and analysing in this research. The results were compared with the experimental test results which were tested earlier. The sample composite deck slabs were modelled and run for analysis by finite element software to obtain the ultimate load and related deflection of slabs under the vertical loading at the center of the deck slabs. The results indicated an acceptable correlation with the experimental test results. In addition, the results of FEA indicated that the horizontal shear resistance is larger by approximately 1.8 times than the required horizontal shear resistance which is in the acceptable range. Keywords: Bridge deck slab, Steel-concrete composite, Shear Connector, Shear resistance, Reinforced concrete INTRODUCTION Composite structures comprising of two different materials have been widely used in many constructed projects including bridges (Kim & Jeong; 2006), high rise buildings (Ahmed et al., 2000, 2002, 2005), tunnel structures (Cui et al., 2015a, b; Shen et al., 2014, 2016; Wu et al., 2015a-c) and other underground structures (Shen and Xu, 2011; Wu et al., 2015d-f). One of the common forms of composite decks used in modern construction projects is composite deck with steel sheeting (Kim & Jeong; 2006). The steel sheeting provides reinforcement for the deck, which plays tension role in the composite slabs and performs additionally as a framework for the deck. This type of composite connection has some advantages over the usage of headed studs such as; simple fabrication, easier erection and installation and better performance (Kim & Jeong; 2009). A number of experimental research studies have investigated perfobond ribs in composite decks using the push-out test method. Furthermore, some studies have been performed on the analysis of perfobond shear connections between
