Abstract
During the past years, many electrical transmission lines have failed during downbursts. This thesis is part of a research program aimed to understand the behaviour of transmission lines under localized winds. The first part of the thesis assesses the dynamic behaviour of the conductors under downburst loading. A non-linear numerical model is utilized to predict the natural frequencies and mode shapes of the conductors at various loading stages. A turbulence signal is added to the mean component of the downburst wind field previously evaluated from a CFD analysis. Dynamic analysis is performed using various downburst configurations.
