Recently, high tension bolt of Fl5T class (SHTB : Super High Tension Bolt) that it got over delayed fracture was developed. There has already been an example that SHTB is being used for in the building field. The bolted joint of the very thick member and the high strength material becomes possible by using SHTB practically. As a result, using SHTB can reduce the number of bolts. In this study, it is analyzed about a fundamental problem to use SHTB. Furthermore, it is evaluated about the economic effect by applying SHTB to the steel girder bridges by trial design.
