✦ Synopsis

The non-resonant dynamic galloping of an iced, electrical transmission line is studied. Conditions and trends for the initiation of galloping have been given previously. Boundaries are presented here at which a periodic plunge or torsional motion loses stability and bifurcates into a quasi-periodic (mixed-mode) motion. Specific attention is given to the overall effects of an iced line's eccentricity and its inertia to mass ratio. These effects are shown to be more complicated than those for the corresponding co-centric line.

The objective of this paper is to investigate the trends of the dynamic behavior of a single iced conductor. Attention is focused not only on the initiation of galloping but also on boundaries where a periodic plunge or torsional motion emerge. Trends with respect to the iced conductor's eccentricit
