Safety Assessment and Fatigue Life analysis of Aged Crane Structures

摘要：

　　The fatigue life of crane steel structure will inevitably decrease in the course of work,which directly affects the work of crane.So the correct safety assessment and fatigue life evaluation is necessary.According to the results of stress testing and non-destructive examination,a framework of assessing remaining fatigue life of crane metal structures is built in this paper based on crack propagation theory.Moreover,in order to descript the analysis process,an example about fatigue life estimation of a shipbuilding gantry crane whose maximum hoist 100 ton was shown.
