“…Meanwhile, there is another study that illustrated with a case study of the line section having suffered two tower failures due to conductor breakages during an ice storm. This study successfully applied cable dynamic model to several examples by using ADINA software (Mcclure and Lapointe, 2003).…”

“…The cable is modeled with a uniform mesh of prestressed tension-only isoparametric truss elements relying on successful previous studies (Jameleddine et al, 1993;Lapointe, 2003;McClure and Tinawi, 1987;McClure and Lapointe, 2003;Roshan Fekr, 1995;Roshan Fekr and McClure, 1998).…”

“…Therefore, damping is modeled by using nonlinear axial dashpot elements parallel to each cable element, relying on previous studies (Lapointe, 2003;McClure and Tinawi, 1987;Jameleddine et al, 1993;Roshan Fekr, 1995;Roshan Fekr and McClure, 1998;McClure and Lapointe, 2003).…”

“…These studies often do not distinguish between the internal damping and the aerodynamic damping [59] but most of them conclude that aerodynamic damping plays an important role in the dynamic behavior of the cables [46,55]. However, the influence of aerodynamic damping on the transient response of a line section still needs to be quantified [52] and is presumably small. In addition, in previous time history analyses of conductor motion [32,42,52,66 and 67], it is stated that the effect of structural damping of the cable is not predominant in the first few seconds of the transient response when peak values are of interest.…”
