Fatigue design codes of steel structures for cranes which have been proposed by ISO, EN and JIS were reviewed. In particular, two general approaches, limit state stress method and allowable stress method, were compared. The limit state stress method, where partial load factors are used to amplify loads before they are combined and compared with limit state imposed by yielding or cyclic loading. The allowable stress method, where the design stresses induced by combined loads are compared with allowable stresses established for the type of member or condition being examined.
