The ratio of rubber sleeve height to stud diameter was found to be the predominant factor.
An extensive parametric study was conducted to study the effect of the changes in stud diameter and concrete strength on the capacity and behaviour of the shear connection.
The effects of headed stud diameter, infill steel plate thickness, concrete panel thickness, number of headed studs as well as aspect ratio of shear wall on the maximum stud shear force are analyzed.
An accurate numerical model was developed and validated against the experimental results, and based on which extensive parametric studies were performed to investigate the variation in concrete strength, stud yield strength, stud diameter and length-to-diameter ratio of stud on the structural performance.

The tests considered two different stud diameters and the effect of concentric and eccentric transverse loading.
It is observed that the AASHTO LRFD specifications overestimated the capacity of the large stud shear connectors, whereas the design rules specified in Eurocode-4 were generally conservative for stud diameters of 22, 25 and 27 mm, and unconservative for diameter of 30 mm.
The present study substantially extends the earlier reliability work for Eurocode 4 by considering a database of 242 push tests, which permits the results presented to be considered valid over a wide range of characteristic compressive concrete strengths (8 ≤ fck ≤ 90 MPa) and stud diameters (12.7 ≤ d ≤ 31.75 mm).
This study examined design parameters, including the embedment depth-to-stud diameter ratio (hef/d), panel thickness, and supplementary reinforcement, in order to propose effective reinforcing methods to prevent premature failure such as pry-out failure.
Test parameters included the type of decks, number of studs, and diameter of studs.
The studs, with diameter of 10 mm, were fixed with epoxy resin.
The ultimate strength and horizontal shear load redistribution of partial composite beams, which had parameters of stud shank diameters and distribution, were evaluated and group failure in shear span was observed.
