Tension tests of friction type high strength bolted joints at elevated temperature were conducted for the fire engineering design of steel structures. The results are summarized as follows: 1) Friction type becomes bearing one in high tension bolted joint beyond 500℃ because of slip load reducing under a half of allowable shear strength for sustained loading. 2) The shear strength of high tension bolt becomes lower than the allowable shear strength for sustained loading near to 600℃. 3) The maximum shear strength of friction type high tension bolted joints can be approximately evaluated from the tensile strength of the bolt materials.
