Shear Connection between Steel and Concrete in Composite Structure

Abstract

For the past few decades, the construction field has been moving towards the usage of steel-concrete composite structural elements in most of its construction. Various research works are carried out to increase the structural aspects of such composite construction. Shear connector between concrete and steel elements in composite construction plays an important role in developing the composite action by ensuring proper shear transfer between the steel profile and the concrete element. The connections between the steel and concrete sections are mostly done using welding, given the durability and strength of welding. For the current study, the shear connectors, connecting the concrete slabs and steel beam, are welded to the flanges of the beam. Given the flexible nature of the shear connectors, they can be available in various shapes and sizes. The performance of each connector was evaluated and compared. The main comparison between the specimens was carried out by comparing the load slip behavior of the specimens.
