In this study, static loading experiments were conducted to clarify the ultimate behavior of high-strength bolted joints subjected to shear and tension, with the flange plate thickness and angle of application as parameters. When the flange plate thickness of the joint is small, there is a range of angles where the fracture of the bolt progress from the shank to the thread portion. In contrast, this tendency was not observed when the flange plate thickness was greater, indicating that the thickness of the flange plate affects the location of bolt fracture. Additionally, a comparison between the design values and almost all of experimental values of maximum strength showed a difference of within 5%, indicating that the dsesign values are generally evaluated with high accuracy.
