Analysis On The Structural Behaviour And Effect Of Shear Connectors In Composite Flexural Members

Concrete is a versatile construction material which has several advantages due to its compressive strength and mouldable shape. But it is weak in tension and has poor ductility. Ductility is an important characteristic of a structure to resist earthquake, impact and blast loading. Steel has excellent ductile property. Hence a judicious combination of structural steel and concrete utilizing the strength possessed by them and suppressing their weakness resulted in the composite construction. A structural member composed of two or more dissimilar materials joined together to act as a unit is referred as composite structure. Joining two dissimilar materials to form a composite member does not only combine the collective strengths of the two materials, forming a union between relevant materials actually enhances their physical characteristics and makes the composite stronger than the sum of their strengths. In order to design the structural member with maximum efficiency and minimum cost, steel-concrete composite construction is adopted. It is a powerful construction concept in which compressive strength of concrete and the tensile strength of steel are almost effectively used. Steel and the concrete have almost the same thermal expansion apart from an ideal combination of strength. Hence, these essential different materials are completely compatible and complementary to each other. Steel-concrete composite structures, particularly, are structures consisting of two materials, a steel section located mainly in the tension region and a concrete section located in the compression cross sectional area. Composite action between the steel and the concrete is achieved by means of mechanical connectors. These connectors are generally dubbed as ‘shear connectors’. They are typically connected by welding to the top flange of a steel beam and cast within the concrete slab. It is only through this connection that composite action is achieved. Without these connectors, the concrete and the slab act independently. The main functions of these connectors are to restrict longitudinal slipping and uplifting at the elements interface and to take shear forces. The project work deals with the analysis of composite beams. Analysis was done using ANSYS finite element software. The model provided by ANSYS is used to simulate the behaviour of shear connectors in composite beam. The parametric studies are conducted to study the behaviour of shear connectors.
