Shear connection with groups of headed studsThe behaviour and characteristics of the elements of prefabricated composite steel and concrete structures are determined by behaviour of the longitudinal shear connection. Headed studs in groups are most frequently used for forming longitudinal shear connection of prefabricated composite beams. The results of experimental research and advanced numerical models of shear connections, obtained using groups of headed studs, are presented in the paper. When headed studs are arranged in groups, it is recommended to use the headed studs with the height greater than the 4d height prescribed by the Eurocode. Posmični spoj ostvaren grupama moždanika s glavom Ponašanje i karakteristike predgotovljenih spregnutih elemenata konstrukcija od čelika i betona određeni su ponašanjem uzdužnog posmičnog spoja. Grupe moždanika s glavom najčešće se koriste za formiranje uzdužnog posmičnog spoja predgotovljenih spregnutih nosača. U radu su prikazani rezultati eksperimentalnih istraživanja i naprednih numeričkih modela posmičnih spojeva, koji su ostvareni grupama moždanika s glavom. Kada se moždanici izvode u grupama, preporuka je da se koriste veće visine od 4d koja je propisana europskom normom.Ključne riječi: posmični spoj, grupe moždanika, predgotovljeni spregnuti nosači Übersichtsarbeit

“…Shim et al [5] performed push-out tests on groups of headed studs arranged with reduced distances between the studs and exposed to cyclic loading. Okada et al [6], [7], Guezouli et al [8], Xu et al [9] and Xue et al [10] conducted push-out tests with the studs arranged so that distances between them were larger, or at least equal to, the minimum prescribed distance of 5d according to EN 1994-1-1 [2]. Okada et al [6] describe the behaviour of headed studs in a group.…”

“…Guezouli et al [8] performed analyses to study the redistribution of shear force between the headed studs within a group. Xu et al [9] investigated the stiffness and shear resistance in biaxial loading of shear connections achieved with groups of studs while varying the lateral bending moment and the shank diameter. In push-out tests presented by Xue et al [10], the distance between studs was varied from 4.5d to 11.4d in the force direction, and the influence of the shear connection stiffness was investigated.…”

Grouped headed studs may be successfully utilized to achieve the longitudinal shear connection between prefabricated slabs and steel beams. The behaviour of the studs and the ultimate resistance of the group were analysed using the results of experimental push tests and by employing advanced FE analyses. Different arrangements of studs in the group were investigated, focusing on minimal distance between the studs. It is demonstrated that the full shear resistance of a group of headed studs is achieved even when the distances between the studs are less than the minimum requirement according to EN 1994‐1‐1. Concrete class C30/37 is the minimum that should be used. Furthermore, the paper presents a new model for calculating the shear resistance of grouped headed studs. The proposed design model is based on an equivalent stud diameter and can be used for various arrangements of headed studs in a group. The shear resistance formula and the requirements for ductility are consistent with the existing Eurocodes. Fatigue loading is not considered in this paper, so the proposed recommendations are valid for buildings including multi‐storey car parks.

In conventional composite construction involving hot-rolled steel section, the composite action is usually achieved by using conventional headed shear studs connectors. However, use of headed studs is not practical for cold-formed steel (CFS) section due to its very thin form that is difficult to weld. A suitable bolt and nut type shear connector was proposed; experimental tests were carried out to evaluate its performance. This study also investigated the use of Self-Compacting Concrete (SCC) integrated with CFS by means of bolted shear connectors to develop composite action. Therefore, the objective of this paper was to investigate the performance of bolted shear connectors in SCC integrated with CFS section as composite beam system. Eighteen push-out test specimens comprising of M12, M14 and M16 sized bolted shear connector of grade 8.8 with longitudinal spacings of 150 mm, 250 mm and 300 mm centers were fabricated, cast and tested until failure. The experimental results showed that all bolted shear connectors possessed a good shear resistance capacity. Not much difference in strength capacity of specimens with M14 and M16 bolted shear connectors was found, perhaps due to CFS failure. Varying the size and longitudinal spacing of the bolted shear connectors revealed that the connectors' strength capacity changed slightly between M14 and M16 bolts specimens but, significantly for M12 bolt specimens.
