Abstract Abstract： This paper proposed a stress intensity factor calculation method for structures under wave loads. The proposed method was proved correct by comparing it with the empirical formulas. Then, the method was applied to the surface crack at weld toe of a bracket between the column and brace of a semisubmersible platform. The results show that the stress intensity factor ranges calculated by empirical formulas are very different from those of the proposed method. The stress intensity factor ranges for all crack sizes of a structure under wave loads can be derived by a part of results obtained by the proposed method.
