Structural fatigue assessment and management of large-scale port logistics equipments

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.
