“…The distance between the web of I-shape connector and the bottom end of the concrete slab was kept constant at 210 mm for all specimens. These dimensions are similar to those used in other push-out tests with other types of shear connectors [11][12][13][14][15]. Most specimens were reinforced longitudinally and transversely with four 8 mm diameter bars positioned in two layers for each concrete slab, for some specimens in Series D, the number of longitudinal bars kept constant while the transverse bars were varied to six and eight bars for each concrete slab.…”

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 another research, Maleki and Mahoutian (2009) investigated the capacity of channel shear connectors embedded in normal and polypropylene concrete both experimentally and analytically. Before a prediction for shear capacity of channel connectors in polypropylene concrete could be reached, an extensive parametric study was performed.…”

In this paper, an attempt has been made to review various types of shear connector in composite structures. This review tries to identify the shear connectors that are most relevant to composite structures and reviews representative journal publications that are related to this topic. It attempts to cover all types of shear connector. The article concludes with a discussion of recent applications of shear connectors in composite structures. Comparative studies, which have been conducted by several researchers, were covered to address the applicability and the efficiency of various shear connectors. The representative shear connectors for stud connectors as commonly used shear connectors in composite structures were discussed and a summary of their behaviour was included.

“…As one of the most well-known C-shaped shear connectors, channel connectors were used primarily in scale-model composite bridges and were initially tested in comprehensive studies by Slutter and Driscoll [8], Pashan [20], and Viest et al [14]. Recently, the behavior of C-shaped channel connectors embedded in different concrete types when subjected to monotonic and low-cycle fatigue loads were investigated by the authors of this paper and by other researchers [15,17,18,[21][22][23][24].…”

“…The interaction between the shear connectors as steel part slab as concrete part using three-dimensional nonlinear performance of the push out specimens causes their mathematical modeling very complicated. This issue is considered in such comprehensive finite element analysis of shear connectors in literature [21,23,45,[47][48][49][50].…”

In this paper a new shear connector called V-shaped angle shear connector for steel-concrete composite system is proposed. This shear connector was proven to improve some mechanical properties of shear connectors, including high shear transfer, uplift resistance, sufficient ductility, and strength degradation resistance under cyclic loading, as well as to being cost effective compared with similar shear connectors, such as C-shaped channel and angle shear connectors. A total of 14 push-out tests were performed on composite beams with these connectors under monotonic and low cyclic loading. The failure mode, shear resistance, and ductility of the push-out specimens were investigated. The study also comprises of finite element and parametric analysis using an effective numerical model of the experimental push-out tests using the program ABAQUS. The finite element models were validated against the test results presented in experimental tests. Results showed that V-shaped angle shear connector has excellent behavior in terms of both shear strength and ductility. In addition, high resistance under cyclic loading was exhibited since the shear resistance of this connector was almost similar in both monotonic and cyclic loadings. Finite element results show good agreement with experimental results. The results discussed on the ductility and strength of this connector with different size and slope of inclination. In addition, the channel and angle shear connectors were compared with V-shaped angle shear connectors. V-shaped angle shear connectors behave much better than other similar connectors, such as normal angle shear connectors, and are superior to channel shear connectors in most specimens.
