A linear relationship existed between the equivalent fatigue limit and the tensile strength of the steel.

By adopting SHELL methods based on the Miner\'s rule,the fatigue equivalent temperature was computed,the formula of day fatigue equivalent temperature was educed,with which the annual fatigue equivalent temperature for eight regions was calculated and fatigue equivalent temperature range of the different regions were discussed.
