Experimental study on fatigue characteristic of high-strength bolted friction type joints using corroded weathering steel

High-strength bolted steel splice plates method is one of effective repair and reinforcement method for the damaged steel member. In the previous studies, there are few cases which such a splice joint part has been subjected to a fatigue test, and it is not clear that the fatigue and the slip characteristics of the splice joint part with damaged weathering plates. The purpose of this study is to investigate the fatigue performance of the high-strength bolted steel splice joints which is one of the repairing and reinforcement methods for existing weathering steel bridge having the damages. In this study, sliding performance tests and fatigue tests were carried out in order to investigate the slip characteristic and the fatigue strength of the bolted joints using corroded weathering steel.
