In this study, we aim to design the bolted joints for ultimate state such as the earthquake of Hanshin Awaji. The main consideration is the capacity of bolted joints for friction type with clearance between bolt and hole after slipping. We carry out the experimental study of the behavior and performance of bolted joints, which involves the slipping and break. We have already examined bolted joints for friction type with main plate whose thickness is 9 mm. In this study, we scrutinize the joints with main plate whose thickness is 19 mm．
