高强度螺栓抗拉节点具有疲劳强度高、施工性好、外观美观等优点，但很少用于桥梁结构主要构件的连接。原因之一是在使用普通1，000MPa级高强度螺栓的情况下的承载能力低。另一方面，近年来开发了1，800 MPa级超强度螺栓。在这项研究中，这种类型的连接使用1800 MPa级超高强度螺栓的力学行为进行了讨论的三维有限元分析的结果的基础上。
The high strength bolted tensile joints are rarely utilized to connect primary members of bridge structures in spite of their good characteristics such as high fatigue strength, workability and good appearance. One of the reasons is that the load carrying capacity in case of using normal 1,000 MPa class high strength bolts is low. On the other hands, 1,800 MPa class ultra-strength bolts have been developed in recent years. In this study, the mechanical behaviors of this type of joins using 1800MPa class ultra-strength bolts are discussed based on the results of 3D-FE analysis.
