The purpose of this paper is to make clear the behavior of friction-type connections fastened with high-strength bolts from the major slip limit . To achieve this objective, an investigation of the relationship between design strength and ultimate limit state, a classification of the limit states of HSFG bolted joint in past experimental studies is conducted. Furthermore a modelling of the contact problem between fastener hole and high-strength bolt using iso-parametric finite element method is carried out . For the results of elasto-plastic finite element analysis, the mechanism of behavior from major slip is clarified and the ultimate limit state including ductility of bolted joint is evaluated.
