为验证有限元分析方法研究栓钉剪力连接件受力性能的可行性和准确性，首先介绍了栓钉剪力连接件的受力机理；其次应用有限元软件ANSYS建立了某大桥组合箱梁的栓钉剪力连接件的实体模型；最后基于有限元模型，对影响栓钉剪力连接件抗剪承载力的混凝土强度等级、栓钉的直径、栓钉的长度、栓钉的材料强度、是否设置贯穿钢筋等5个相关参数进行相应的分析．通过将其计算结果与经验公式进行对比分析，得到了栓钉连接件极限抗剪承载力的建议公式，为以后的实际应用和设计计算提供参考．

英文摘要：

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.
