Abstract In order to verify the feasibility and accuracy of finite element analysis on the mechanical performance of stud shear connectors， the mechanical behavior of stud shear connector was introduced. The solid model of stud shear connectors of composite box girders in a bridge was established by finite element software of ANSYS. Based on the entity model, five relevant parameters which affected the shear bearing capacity of the stud shear connectors were analyzed. The relevant parameters included the concrete strength grade, the stud diameter, the stud length, the material strength of stud and setting perforated rebar or not. Comparing the calculated results with those obtained from empirical formulas, the recommended formula of ultimate shear capacity for the stud shear connectors was obtained.
