| Abstrait: |
The component of bolted connection is sometimes replaced due to some reasons, which are corrosion, bolt delayed fracture and so on. The influence or mechanical behaviour of bolt replacement of bolted connection applied tensile force was already investigated in previous studies. However, that of the connection applied the bending moment is not cleared. In this study, simple and small specimens of bolted connection were prepared and bolt replacement experiments under bending were conducted to clear the behaviour and compare it and that of bolted connection applied tensile force. And, numerical analysis was carried out to investigate the influence of bolt replacement focused on the order of bolt replacement. As a result, although the centre opening stretch of the upper side and the lower side was different due to bending, the averaged opening stretch was the same as that of the connection in tensile. The order of bolt replacement affected the opening stretch, however, did not affect the elongation of bolted connection. |
