“…The corresponding peak slips of specimens V3 and 0.3HV3 are 2.52 mm and 2.29 mm, respectively, occupying 90.6% and 82.4% of specimen V1. These results demonstrate that the group stud effect decreased the shear strength per stud, which is consistent with findings in previous studies 18,19 . In contrast, the application of transverse shear force exacerbated this detrimental impact.…”

“…17 While adding more stud rows can boost the shear strength of the connectors, the group stud effect reduces the shear capacity of individual studs. 18,19 In addition, fatigue loading can decrease the residual bearing capacity and shear stiffness of stud connectors. 15 The residual bearing capacity decreased slowly in the early stage, but the decrease accelerated in the later stage.…”

“…It was reported that the shear capacity and fatigue resistance of stud connectors are highly sensitive to the stud diameter, yield strength, and concrete strength 17 . While adding more stud rows can boost the shear strength of the connectors, the group stud effect reduces the shear capacity of individual studs 18,19 . In addition, fatigue loading can decrease the residual bearing capacity and shear stiffness of stud connectors 15 .…”

Stud connectors in steel-concrete composite track beams of straddle-type monorail transits experience longitudinal and transverse shear forces. Little is known about the effect of transverse shear forces on stud connectors; thus, further research is needed to evaluate the serviceability of steel-concrete composite track beams. This study investigated the shear performance of stud connectors subjected to bidirectional shear force by means of modified pushout tests and finite element (FE) analyses. The test results demonstrated that the presence of transverse shear forces significantly decreased the vertical shear strength and stiffness of the stud connectors. In addition, the group stud effect aggravated the reduction in shear strength and shear stiffness per stud under bidirectional shear forces. The transverse shear force also considerably affected the failure modes of the stud root and the damage range of the concrete. Furthermore, the numerical results were verified using the test results in terms of the load-slip relationship and failure modes. Based on the verified FE model, the strength reduction factor of stud connectors was proposed incorporating the presence of transverse shear force, and the decreasing trend of stud shear strength under bidirectional shear force was presented. This study provides additional data for formulating design rules of stud connectors in monorail steel-concrete composite track beams.

“…Steel-concrete composite beams have been widely applied in civil engineering, such as in buildings [1][2][3], floor systems [4] and bridges [5][6][7][8]. Compared with steel or reinforced concrete beams, the composite beam system has increased flexural strength and stiffness with reduced beam weight and depth due to composite action between the two materials [9,10].…”
