“…Oliveira et al [3] and Cardoso [7] carried out an experimental study composed of CFCCs of circular and rectangular cross section in which the Crestbond shear connector was applied as a load transfer device. The tests were conducted based on the guidelines in annex B of EN 1994-1-1:2004 [14] for standard push test (Figure 3a), and the results obtained were used for the development of a representative numerical model [4]- [6] (Figure 3b). This finite element (FE) model was created in Abaqus using 8-node brick elements (C3D8), with seed size of 8 mm in the Crestbond and surroundings.…”

This paper presents a numerical study of the Crestbond shear connector, characterized by a steel plate with regular cuttings, when used as a load transfer element in concrete filled composite columns in fire. The developed numerical model was calibrated with experimental results of composite columns in fire and later the load transfer devices were inserted. Numerical analyzes were performed with the software Abaqus and comprised the variation of the composite column diameter and of the loading levels, as well as the comparison with the results obtained when is used a through steel plate without cuttings (Shear Flat) as a load transfer device. With the analyzes performed, it was observed that the Crestbond shear connector and the Shear Flat present very similar thermomechanical performance in relation to the load transfer capacity. Thus, the Crestbond shear connector has the potential to be applied alternatively to the Shear Flat as a load transfer device in concrete filled composite columns, with the advantage of the possibility of associate use of longitudinal and manly transverse reinforcement.

“…The ¾ scaled experimental evaluation characterized the composite connection utilizing a through plate with rigid shear connectors as a fully restrained strong panel elastic nature. Whereas, Aguiar et al [98] utilized Crestbond shear connectors (steel plate with regular cuttings similar to puzzle shape composite dowels used as shear connector shown in Fig. 7 (b)) in concrete filled-steel tube columns at the beam-column interface for shear load transfer.…”

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.
