STUDY ON DUCTILITY BEHAVIOR OF DIFFERENT TYPES OF SHEAR CONNECTORS IN COMPOSITE STRUCTURAL ELEMENTS

Composite Structures have several advantages over traditional reinforced concrete which incorporate high strength to weight ratios, dimensional stability and structural integrity. Late years have seen a considerable increment in the utilization of composite structures and improved research went for creating new strategies for combining steel and concrete. composite structures result in efficient design and economy in construction time hence used especially in construction of building floors and bridges. Wide construction practices involve connecting Concrete slab and hot rolled steel beam sections by shear connectors. Shear Connectors are used to enhance proper connection and resist horizontal shear forces. A Composite member has to be designed in such a way that before composite structural element reaches ultimate capacity, shear connectors should not fail due to lack of ductility. In this study Finite Element Analysis has been done on four types of shear connectors for ductility criteria. Push-out test Specimen and Composite beam modeling with four different types of shear connectors is done in ANSYS and are analyzed. The Analytical results are presented and focused on the study of ductility behavior and load slip behavior of connectors of varying height in composite beams.
