“…The nonlinear compressive and tensile stress-strain behavior of concrete is presented by an equivalent uniaxial stress-strain curve as shown in Fig. (7). The Concrete Damage Plasticity model available in ABAQUS material library was adopted to model the non-elastic behavior of reinforced concrete.…”

“…The V-shaped angle shear connector [4], for instance, exhibits several satisfactory proprieties such as ductility, elevated resistance, high shear transmission, and it is more economical than other shear connectors [4]. The newly suggested Lshaped, C-shaped, and I-shaped shear connectors [5][6][7] can efficiently provide adequate mechanical performances. Furthermore, high-strength friction-grip bolts were proposed as shear connectors [8].…”

“…Paknahad et al [18] recently estimated experimentally and analytically the effect of high-strength concrete (HSC) on the shear capacity of the channel shear connectors (CSC) in the steel concrete composite floor system [18]. An interesting connector type known as an "I-shaped" shear connector was tested under static loading [7,19]. The test results show that in composite beams, I-shape connectors can be used to transfer the longitudinal shear forces and limit the interfacial slippage between the steel and concrete.…”

A great deal of research has been conducted to improve the understanding of the behavior of new types of shear connectors. This article presents the study of I-shaped connectors behavior under monotonic load welded in four different orientations in order to get the position which gives the high shear strength and the best ductility. For this purpose, eight push-out test specimens with I-shaped shear connectors with different orientations and dimensions were tested in C20/25 and C30/37 concrete classes. The load-slip behavior and failure modes of the tested connectors are presented and discussed. Furthermore, a non-linear 3D finite element modelling of the push-out test is performed in order to further investigate the influencing parameters on the I-shaped connectors behavior. Hence, a parametric study is carried out by using the established 3D finite elements model to study the influence of concrete strength, connector’s steel grade, reinforcements, height and length of the connector. Both experimental and numerical results show that there is a privilege orientation for which the shear strength of an I-shaped shear connector is significantly higher than that of all other tested orientations.

“…On the other hand, the angle type is higher than anchor one in strength, so only a few number of angle type connectors can be installed. To date, many experiments about angle-type shear connector have been conducted and researchers have determined that the strength and ductility change according to the height of the angle (Balasubramanina and Rajaram 2016;Pashan 2006;Shariati et al 2012Shariati et al , 2013Mazozl et al 2013;Titoum et al 2016). However, research on angle-type shear connectors in concrete-filled composite structures has been insufficient so far, the study is addressed in this paper.…”

Strength Evaluation of Angle Type Shear Connectors in Composite Beams

et al. 2020

Composite structures are used in structural systems to take advantage of concrete and steel, and the role of shear connectors between the two is extremely important. Currently, anchor-and angle-type connectors are mainly used as shear connectors, and the angle type offers several advantages over the anchor type. The angle type can be manufactured as a shape that fits the composite structure with a greater basic strength than that of the anchor type, so it can be installed in wider spaces. Much research has been conducted on the anchor type, but that on the angle type has been insufficient so far. In this study, pushout and yield-strength tests were conducted on various angle-type shear connectors used for filling-type composite beams. The variables included the height, width, and thickness of the angle-type shear connector. The tests were terminated when a strength reduction of 80% of the maximum strength occurred. The slip capacity of the specimen was evaluated by referring to Eurocode. Based on the experimental results, the design equations have been reviewed to determine whether or not they can be used for the shear connection of concrete-filled composite beams. In addition, the strength was assessed by existing design equations. Meanwhile, a new design equation was proposed, including the height of the shear connector, which is not considered in the current design equations. The other strength was calculated by the new design equation.

“…The effect of long-term load on the overlaps in the area of anchors was investigated in [12]. Futher, for joining reinforced concrete slabs anchors in the form of bolts [13], angles, Ibeams and channels [14,15] are used. To connect a reinforced concrete slab with a steel beam are also used inclined and vertical supports made of reinforcing bars with a bend at the end.…”

Reinforced concrete floors and steel beams are widely used in buildings and structures for various purposes. Reinforced concrete overlaps can be cast-in or precast of hollow-core slabs. The most effective floors in which the concrete slab is located in the compressed area of cross-section, in steel beams in the tension zone, and shifting forces, arising between concrete slab and the steel beam, are perceived by anchors. Precast slabs in comparison with cast-in ones have less labor-intensive performance, the beam spacing is equal to the span of reinforced concrete slabs, there are no intermediate beams in such overlaps, that allows to reduce the floor thickness. The inclusion of precast in steel-concrete cross-section requires joints with steel beams, which requires using of special anchors. Anchor perceives shear forces and ensures the joint operation of the plate and the steel beam. In addition, for beams with narrow flange, the anchor device can provide the required width of the support slabs. The calculation of the attachment points of the anchors to the steel beam is carried out using three variants of calculation methods, which allow to determine the forces acting on the anchor. For practical application, a wire-element model has been proposed and managed to get forces in a steel beam, slab and anchors the width of the slab recommended by the standards should be included in the calculation model.
