ABSTRACT
In 1999, economic losses that were initially predicted to be only 600 million USD turned into 10 to 12 billion USD due to damage to high-voltage line transmission towers caused by the Chi-Chi earthquake in Taiwan. Damage of electricity transmission towers were observed due to earthquake in Lushan, 2013. As this infrastructure is essential for productivity and economic growth of modern society, therefore it is important to study the seismic risk of transmission tower so that later mitigation can be carried out and losses can be minimized. This paper aims to evaluate transmission tower seismic risk by developing its fragility curves. An existing transmission tower was 3D modelled using finite element software. An adaptive pushover analysis was employed to determine the nonlinear global behaviour of the tower structure and obtain its capacity curve. Damage states were then identified and determined namely slight, moderate, and extensive damage. Fragility curve was then developed describing the exceedance probability of different damage states as a function of earthquake intensity. This quantitative value provides rational basis for evaluating seismic risk of transmission tower.
