Analytical study on wind-induced vibration of power transmission towers

Abstract This paper describes a method for analyzing wind-induced vibrations of power transmission towers coupled with power lines and the results of two case studies. It also discusses the influence on response characteristics of differences in transmission support systems and differences between peak factors, computed from a time -series and from power spectrum density. The results of this study show that differences in the way power transmission towers support power lines have an influence on response characteristics, and peak factors computed from a time-series response are greater than those computed from power spectrum density.
