Review of Various Shear Connectors in Composite Structures

Abstract

Shear connectors are devices that provide shear connection at the interface of steel girders and reinforced concrete slabs in composite structures to accomplish composite action in a flexure. The seismic response of composite structures can be controlled using properly designed shear connectors. This state-of-the-art review article presents considerable information about the distinct types of shear connectors employed in composite structures. Various types of shear connectors, their uniqueness and characteristics, testing methods and findings obtained during the last decade are reviewed. The literature, efficacy, and applicability of the different categories of shear connectors, for example, headed studs, perfobond ribs, fibre reinforced polymer perfobonds, channels, pipes, Hilti X-HVB, composite dowels, demountable bolted shear connectors, and shear connectors in composite column are thoroughly studied. The conclusions made provide a response to the flow of the use of shear connectors for their behaviours, strength, and stiffness to achieve composite action.

Performance Evaluation of Innovative Coconut Palm Stem Shaped Stud Shear Connector for Composite Structures

“…As a result, shape, shearing area, and inertia are the most important factors to consider while ensuring the connection (Tabet-Derraz et al [12]). Several categories of shear connectors have undergone a great deal of development and study over the last few decades (Pardeshi and Patil [13]). However, in composite construction, the headed stud is the more frequently utilized shear connector.…”

Fatigue Experiment Study on Internal Force Redistribution in the Negative Moment Zone of Steel–Concrete Continuous Composite Box Beams

“…Compared with ordinary reinforced concrete beams, steel–concrete composite beams exhibit the advantages of light weight, small cross-section, good ductility, and high seismic resistance [ 1 , 2 , 3 ]. Since the 20th century, steel–concrete composite beams have been widely used in bridge structures [ 4 , 5 ].…”
