Abstract:

This paper studies the vibration characteristics of continuous spans with only one galloping span. The finite element model of continuous spans is set up by means of ABAQUS softwart,and the aerodynamic load is determined by the UEL. The time domain solutions for the vibrations of the continuous spans are obtained with consideration of the non-linear influence. The effects of span and galloping amplitude are investigated, which may provide some guidance for prevention of conductor galloping.
