In this paper, a method of constructing fatigue load spectrum sequences under multiple load and working conditions based on the simplified fatigue load calculation formula is proposed. For easy understanding the loading sequence on fatigue crack growth, three details in a large container ship are taken as examples for discussion. In the analysis, different generating fatigue load spectrum for lager container ship details combining with the unique crack growth rate curve model to calculate the crack growth under different fatigue loading spectra have been performed. For performing the calculation and guarantee the calculating accuracy, a program code, based on the proposed procedure, has been compiled in MATLAB. Using the codes, the effect of fatigue loading sequence has been discussed. The different order of fatigue loading stages has a big influence on the crack propagation when considering the SIF threshold. In addition, the method of constructing fatigue load spectrum sequence under multiple load and working conditions needs to be further examined.
