In this paper, the evaluation equations proposed by Tange et al. and Ando et al. were used to evaluate the threshold stress intensity factor △K(R/th(s)) and fatigue limit , △σ(R/WC) according to the small crack of offshore structural steel F690. Despite the differences in concept and shape of the two equations, the △K(R/th(s)) and △σ(R/WC) proved completely consistent. It is possible to use these equations to evaluate the dependence of the crack length on the △K(R/th(s)) and △σ(R/WC) of structures made of all steel grades. With these equations, the characteristics of microcracks can be quantitatively evaluated, and the safety and reliability of the structure can be secured.
