The hot spot stres approach is usually adopted in the fatigue design and analysis of tubularwelded joints. To apply the hot spot stres approach for fatigue evaluation of long span suspensionbridges, the FEM is used to determine the hot spot stres of critical fatigue location. Using the local finiteelement models of the Tsing Ma Bridge, typical joints are developed and the stres concentration factorsare determined. As a case for study, the calculated stres concentration factor is combined with thenominal representative stress block cycle to obtain the representative hot spot stress range cycle blockunder traffic loading from online health monitoringstres approach and the hot spot stress approach for fatigue life evaluation of the Tsing Ma Bridge. Thecomparison result shows that the nominal stress approach cannot consider the most critical stress of thefatigue damage location and the hot spot stress approach is more appropriate for fatigue evaluation.
