Study on Ultimate Bearing Capacity and Anti-Slip of the Stud

Abstract

Based on the test data of twelve push-out specimens with different holes filling different materials,the paper compared and analyzed the capacity and the corresponding slip value of the stud shear connector. The results show that, as to the two different kinds of holes shape ,the strength of the stud shear connectors of square push-out specimens was huger than that of circular specimens with the same condition; the strength of stud shear connectors in steel-concrete composite structure was decided by the strength of concrete surrounding the shear in the holes, with increasing concrete strength, the strength of stud shear connectors improved greatly; The outputs of this study are very useful for further understanding of the characteristics of the stud,it is also expected that the results presented in this paper should be valuable for the design of the composite beams.
