It is found that the fatigue damage failure is the main reason for the metal structure failure of crane in service after the investigation and analysis of many accidents.Predicting fatigue damage for crane in service subjected to variable loading conditions is a complex and important issue.In this paper,current accumulation damage was classified,advantage and disadvantage of every fatigue accumulation damage method were analyzed,the problem existed in current fatigue accumulation damage field was provided,and provided suggestion for future development direction of this field,to promote the study of fatigue accumulation damage theory.Finally,calculating and analyzing the fatigue and damage life of came in service by getting a load spectrum base on Miner linear accumulation damage method was given.
