Abstract: With the advances of port enterprises, much intensive research has been gradually involved in the structural fatigue assessment and management of port logistics equipments. However, relevant work on large-scale port logistics equipments is still lacking due to their complex structures. In addition, a single technique could not effectively deal with complicated structures. As such, a hybrid fatigue assessment method was investigated using the S-N curve and fracture mechanics methods for crack formation and propagation life estimations, respectively. Consequently, the fatigue assessment of a gantry crane was used as an example to illustrate the practicality and efficiency of this approach.

Keywords: large-scale port logistics equipment; fatigue assessment; S-N curve; fracture mechanics; crack formation; crack propagation life; gantry cranes; structural safety assessment.
