摘要
焊缝补强型栓焊并用连接的模拟受力过程与以往学者的研究不同。基于焊缝补强型栓焊并用连接的相关试验数据,本文对焊缝补强型栓焊并用连接节点的受力性能进行有限元模拟,验证了有限元模型的可靠性;并基于有限元算例结果进一步分析了焊缝补强型栓焊并用连接节点的承载性能,为栓焊并用连接节点的设计提供依据。
The simulate force process of weld reinforced combined connections with bolts and welds is different from the previous scholars. In this paper,the finite element method is used to simulate the carrying performance of weld reinforced combined connections and the reliability of the finite element model is verified. Furthermore,based on the results of finite element analysis,the carrying capacity of the weld reinforced combined connections is further analyzed,which provides the basis for the design of combined connections with bolts and welds.
