Abstract Wind-induced loads cause electrical transmission line fatigue. Evaluation procedures consider descriptors such as deflection amplitude ( Y b ) and far-field vibration ( fy max ), which cannot relate endurance limits and wire loads. The investigation uses the finite element (FE) strategy developed in part I to study Aluminum Conductor Steel Reinforced (ACSR) submitted to wind-induced loads. The analysis underlines the Y b and fy max discrepancies. A factorial design leads to a model relating them with a precision of 92%. Comparisons with experimental ACSR data indicate that fatigue predictions from the Coffin-Manson relation associated with the FE model provide realistic evaluations of service lives.
