摘要
芜湖公铁两用长江大桥上层公路桥采用混凝土桥面系与钢桁组合梁，连接件为栓钉，节点附近栓钉的布置为密集型大吨位．为确定芜湖桥栓钉承载力设计值，完成了3000～5000kN栓钉群钢-混凝土组合件的极限承载力试验和有限元分析．该成果已用于芜湖桥的设计．
Wuhu Yangtse River Bridge is a composite structure of steel trusses and concrete slabs. Its shear connectors are headed studs. Within the joint area many studs should be closely arranged to resist the large shear force In order to give the design strengtyh of a single stud, 3000~5000kN push-out tests and numerical analysis of composite specimens with large number of studs are finished. The results have been used in the design of the bridge.
