PROPOSED DESIGN METHOD OF COMBINED CONNECTIONS WITH BOLTS AND LONGITUDINAL WELDS FOR STEEL STRUCTURES
-
摘要: 栓焊并用连接在钢结构加固工程中有广泛的应用。但由于螺栓连接和焊接连接承载能力的不同,栓焊并用连接节点的受力性能比较复杂。JGJ822011《钢结构高强度螺栓连接技术规程》提出了栓焊并用连接的设计方法。基于试验和有限元参数分析,指出JGJ822011设计方法的不足之处未考虑螺栓与焊缝的强度对比关系,提出新的栓焊并用连接承载力建议设计公式,并用国外学者试验研究提出的设计公式与JGJ822011中的设计公式进行比较。对比结果表明,提出的建议公式具有较好的安全性和可靠性。Abstract: The combined connection with welds and bolds can be widely used in reinforcing the joint in steel structure.In this paper,a proposed design method of combined connection with bolts and longitudinal welds was given based on the tests and finite element analysis(FEA).The was method considers the effect of the strength ratio between bolts and welds.The safety and reliability of the method were verified by FEA and also compared with other design method.The design method can contribute to the promotion of the application of the combined connections.
