EXPERIMENTAL INVESTIGATION OF COMPOSITE DECK SLAB WITH CASTELLATED BEAM

Deck slab with profiled sheeting turns to be an optimal choice in the construction of composite floor system. This thesis is focused on performance of profiled deck slab over steel castellated beam. The castellated beam was fabricated by expanding a standard rolled shape in a manner which creates a regular pattern of holes in the web. Modelling and analysis of composite deck slab with castellated beams will be done by ANSYS software and the single test specimen of castellated beam and composite deck slab with appropriate scale is casted. Concrete grade of M30 and hot rolled steel is adopted for beam section and then cold form steel is adopted for profiled sheet. Stud type shear connector is employed which promotes the composite action at the interface of steel and concrete. Therefore, an experimental test is carried out to investigate the load carrying capacity under cyclic loading. In terms of theoretical and experimental techniques, performance of composite deck slab will be analyzed. From the results it has proven that the composite deck slab over castellated beam section increases the load carrying capacity than other type composite deck system
