ABSTRACT
One of the most important structures in modern civil engineering is composite beams, which refer to beams that consist of different materials whereby the most common are concrete slabs and steel beams. This paper aims at presenting the state of research on the behavior and performance of composite beams emphasis has been put on the Shear connections. Some of the commonly used shear connectors include headed steel studs, channel connectors, and angle connectors, which improve the load bearing of steel and concrete structures. Literature review shows that important parameters such as connection type, concrete strength, and connection layout have been found to affect considerably the ultimate moment, the fatigue behavior, and the failure mode of the connection. In particular, it is important to mention that new materials, such as ultra-high performance concrete (UHPC), and connector designs offer the potential for increasing loads and durability of connections. It is within this context that this review underlines the need to identify and manage design parameters to guarantee the safe and efficient use of composites in beam structures.
