Abstract
High voltage transmission towers are key linear assets that supply electricity to communities and key industries and are constantly exposed to wind effects where they traverse steep topography or open terrain. Lattice type high voltage transmission towers are highly optimised structures to minimise cost and reserve strength at design wind speeds (Albermani and Kitipornchai, 2003). The structures are tested under static loading conditions for specified load cases at the design stage. However, the interconnected nature of the lattice towers and conductors present a complex response under dynamic wind loading in service (Fujimura, el.al., 2007). The transmission tower's survival under severe wind and additional load transfer due to collapse of its neighbours is difficult to assess through modelling. Furthermore, the lack of data in the industry doesn't allow for a probabilistic analysis based on history (Abdallah, et.al., 2008). Hence, there is a need for developing an alternative methodology for analysing transmission tower collapse and survival of transmission lines subjected to cyclonic winds utilising design information, limited field data and industry expertise.
