ABSTRACT
The effective height of studs is an important parameter in simulating the load-slip curve of stud shear connectors. In order to determine the range of deformation of studs along the height direction in the elastic stage, the relationship between the effective height and the equivalent shear stiffness of the single stud is deduced by using the energy equivalent model, and the effective height of studs is 7.5 times of the diameter of studs according to the available experimental data. In this paper, the push-out test results of stud shear connectors with different height-diameter ratios are compared with the theoretical shear stiffness of the stud with standard height-diameter ratios of 7.5 times. The results indicate that the shear stiffness of the stud is in good agreement with the theoretical value after the height of the stud reaches 7.5 times of the diameter of the stud, and then remains stable with the increase of the height of the stud.
