“…The load capacity, the ductility and the modes of failure were presented and discussed. The effect of the dimensions of I-shape connector, the effect of strength of concrete, and the effect of the number of transverse reinforcing bars have been discussed [7]. Furthermore, a finite element modelling of the push-out tests was carried out using ANSYS software [8] to investigate the stress distribution pattern in the area of the I-shape connector.…”

ABSTRACT:In this paper, we present the results of experimental study and finite element modeling of the push-out tests on a new shear connector of I-shape. 24 push-out specimens with I-shape shear connectors were tested under a static loading in the Laboratory of Materials and Mechanics of Structures -LMMS at the University of M'sila, Algeria. The test specimens were designed to study the effect of the following parameters on the ultimate load capacity: the height of I-shape connector, the length of I-shape connector, the compressive strength of concrete and the number of transverse reinforcing bars. The load capacity, the ductility and the modes of failure were presented and discussed. Furthermore, a finite element modelling of the push-out tests was carried out using ANSYS software to investigate the stress distribution pattern in the area of the I-shape connector. Moreover, the finite element model was also used to simulate another type of shear connector, called channel connector in order to compare its behaviour with that of the I-shape connector. From this comparison, we suggested an equation for the prediction of the ultimate load capacity of I-shape shear connectors.

“…In steel and concrete composite structural systems, the transfer of shear forces between steel and concrete materials should be ensured by arranging different types of shear connectors, such as stud connectors (Shim et al 2004;Xue et al 2008), perfobond rib connectors (Cândido-Martins et al 2010;Zheng et al 2016), T-perfobond rib connectors (Vianna et al 2008), Y-type perfobond rib connectors (Kim et al 2014a;Kim et al 2013;Kim et al 2014b), channel connectors (Baran and Topkaya 2012), angle connectors (Shariati et al 2014), hat-shaped connectors (Kim et al 2011), I-shaped connectors (Mazoz et al 2013;Costa-Neves et al 2013), J-hook connectors (Richard Liew and Sohel 2009), and puzzle-shape composite dowels (Lorenc et al 2014a;Lorenc et al 2014b). Stud shear connectors and perfobond rib shear connectors are commonly used in steel and concrete composite structures.…”

This study investigates structural behavior of shear connectors in glass fiber-reinforced polymer (GFRP)-concrete composite bridge deck slabs. Five kinds of push-out specimens with GFRP shear connectors were prepared and tested. The failure modes of the specimens were observed, and the load-slip curves were obtained. The effects of rib shapes, presence of holes, and existence of transverse rebars on failure mode, shear resistance, and ductility were investigated. Results showed that (1) the shear resistance and ductility of T-type rib shear connectors were greater than those of flat plate shear connectors. (2) Shear resistance and ductility were significantly improved by holes. (3) The transverse rebar has a significant influence on the failure mode. The concrete slabs in the specimens without a transverse rebar failed. Similarly, the GFRP shear connector in the specimens with a transverse rebar collapsed. (4) All of the specimens showed a similar failure mode caused by the shearing failure of the connectors in the root when the transverse rebar was applied. Furthermore, the shear resistance and ductility of GFRP shear connectors decreased as the number of transverse rebars increased. Empirical equations were proposed to predict the shear resistance and validated with the test data.

Shear connectors are designed in steel-concrete composite construction to transmit the longitudinal shear, to prevent separation of steel and concrete slabs, and also to increase the structural efficiency of the whole system. In this study, the performances of different types of shear connectors in steel-concrete composite specimens are evaluated by conducting push-out tests under monotonic loading conditions. An ISMB 200 @ 25.4 kg/m universal steel beam measuring 400 mm and a reinforced cement concrete slab measuring 300 mm with a breadth of 200 mm and a thickness of 200 mm reinforced with 8 mm diameter steel rods are used for the experimental study. The results reveal that the load-slip relationships for various types of shear connectors and failure mechanisms are obtained to identify those shear connectors which are more relevant to the steel - concrete composite members.
