“…Structures must have appropriate resistance to control the lateral displacements to restrain any structural and non-structural damage during the moderate but frequent earthquakes and also must have appropriate ductility and stability to restrain collapse under severe earthquakes. The capability of energy dissipation and having an appropriate stiffness is one of the most important specifications of a lateral load resisting system [1][2][3][4]. On the other hand, under a moderate earthquake, it is not economically justifiable to designing a structure which remains elastic [5][6][7].…”

This paper treats a different type of bracing by using circular bracing elements called OGrid-H. The goal of using circular shape is to obtain more ductility, high performance and appropriate stiffness and limit the buckling of braces, and at the same time in order to realize a solution that is interesting from the architectural point of view. In order to study the seismic behavior of OGrid-H members, a numerical finite element analysis of 9 OGrid-H models with different section members is established through ABAQUS finite element software subjected to cyclic loadings, which failure modes, load capacity, nonlinear displacement, ductility factor, vibration period, stiffness and energy absorption of models is obtained, and the comparison between outputs of models leads to obtaining the model with the best sections which have higher performance than the others. In order to investigate the OGrid-H connections, five changes are applied on connections, which the results showed that three changes had the greatest influence, which caused to increase load bearing as the amount of 22.88%.

“…Since the use of C-shaped shear connectors can be efficient in composite beams, the authors of this research conducted relevant investigation on behaviour of C-shaped angle shear connectors under fully reversed cyclic fatigue loading as well as the efficiency of such connectors [16,35,36]. Cyclic pushout test is of interest for understanding the performance of composite beam under fatigue or seismic loads and has been applied for many types of shear connectors [17,[37][38][39][40][41][42].…”

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.

“…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.
