Finite Element Analysis of Group Studs in Steel-UHPC Composite Slab
To explore the shear behavior of headed studs in steel-UHPC (ultra-high-performance concrete) composite slab, the refine finite element model considering the effect of weld collar was proposed. Based on the FE model verified by the test results, the influence of diameter and spacing on the stud shear performance was discussed. The analytical results reveal that weld collar in the headed stud can significantly increase the shear bearing capacity of the stud. The shear bearing capacity of the stud is remarkably influenced by diameter and spacing. With the increase of the diameter and shorten spacing, the UHPC slab will crack or could even represent splitting broken. It was suggestion that the minimum spacing of 13 mm stud should greater than 2.5 ds, while the corresponding results were 3.5 ds for 16 mm and 19 mm studs. When the spacing of 13 mm, 16 mm, and 19 mm studs is less than 3.5 ds, 5.0 ds, and 6.5 ds, respectively, the group stud effect should be considered in shear bearing capacity of the studs, which may be taken as 0.93.
