中文摘要	提出一种中等直径(10~16mm)钢筋在钢筋混凝土结构中的新型连接方式,通过焊搭混合连接降低施工难度、节约钢筋用量。对比现行规范规定的钢筋连接方法,研究其受拉性能,制作了非埋入式和埋入式钢筋连接2组试件,共完成了138个钢筋连接的拉伸试验,得到无横向配筋约束的改良焊搭混合连接钢筋的破坏模式和承载力,并用有限元软件进行了模拟和验证,对破坏机理进行分析。试验结果表明:该方法简单易行,能够实现在钢筋混凝土结构中的可靠连接,承载力满足要求,破坏模式合理。基于试验结果,对焊搭混合连接的工程应用提出了建议。进行了工程实例的经济性分析,证明了该连接具有很好的经济前景。; An improved splice method for mid-diameter steel bars(10-16mm)used in RC structures was developed,which can make the installation more easily and economic through the hybrid connection of welding and overlapping.In order to study the mechanical behavior of welding-overlap splices,a total of138steel bar splice tests were conducted,including both the steel-concrete interaction group and the lonelysteel group.Through the splice tensile experiment,the failure model and ultimate strength of the improved splice was summarized.Meanwhile,the failure mechanism was analyzed by the FEM analysis.The test results show that:hybrid connection of welding and overlapping is a simpler splice method which can realized the reliable splice in the RC structures,the ultimate load of the improved splice is sufficient for the application and the failure model is reasonable.Base on the test results,some suggestions for application were given.The economic analysis of a real application case is conducted,which shows a good prospect of proposed connection.
