Abstract
Fatigue is one of main failure forms that the steel structure loses its functions under fluctuating loads. Take a container crane for example, the randomness of lifting load and trolley reaching positions, namely load probability and position probability, are the most obvious characteristic when loading and unloading containers on the ship. Correspondingly load spectrum and position spectrum is constructed to estimate the crack growth remaining life by using Paris’ Law and then the periodic inspection interval is proposed to conduct the structural risk management. A real case is analyzed in accordance with the risk assessment process mentioned in the paper and successfully explains which members to inspect, where to inspect, and how to inspect. At last the inspection interval is recommended based on the field structural monitoring data and it is economical and feasible.
