In order to analyze the redundancy of steel frames in fire, it is important that the load-deformation behaviour of friction type high strength bolted joints at elevated temperature is clarified. In this paper, influences of plate thickness, end distance, fastening of bolts and steel temperature on the deformation behaviour of the bolted joints are discussed on the basis of the elevated temperature tensile test results. In case the plate is thin and the failure mode is tear-out, the ductility of

However, if the failure mode is changed from tear-out to bolt in share due to increase of temperature or end distance, the ductility of the joints decreases. Fastening of bolts slightly affect the load-deformation behaviour of the bolted joints at elevated temperature.
