In recent years, the use of composite beam in buildings has become widespread. Shear connectors used in beam composite such as stud, channel and bolt preserve slipping between steel beam and concrete slab. In this thesis, deflection of composite beam with blind bolt including two types of nuts is analysed with three dimensional non-linear finite element method by Abaqus software. The results of this analysis illustrate that deflection of beam is not affected by changing the types of nuts. Moreover, four loading positions are studied. In a loading position, shear forces loaded on the two opposite sides of concrete slab lead to torsion momment and flexure moment simultaneously resulting in maximum deflection at mid span. In the other loading position shear forces which cause flexure momment and torsion of 17500 KN.mm simultaneously in composite beam lead to less deflection of composite beam than under loading pure flexure .
