Due to the inherent and unavoidable defects of the steel structure of the bridge, CTOD (crack tip opening displacement) tests were carried out on E43 steel specimen under a condition of fatigue. The results provide an experimental base and computing foundations for the bridge steel-using. In this paper, CTOD fatigue pre-cracking tests for E43 steel was studied.
