Fatigue analysis for civil aircraft fuselage typical truss joint in serving environment was discussed, in which detail fatigue rating (DFR) method in corrosive environment was used. A way was presented to determine DFR-corrosion-influence-factor of structural element in serving environment by the DFR-corrosion-influence-factors obtained by tests with detail simulation specimens in typical laboratory environments. A pre-corrosion and corrosion-fatigue alternated experiment, corresponding to a given serving condition, with typical truss joint simulation specimen of civil aircraft was conducted. The comparison between the analysis conclusion and the test result shows the validity of the method.
