- Abstract
High Voltage Transmission Tower is an important for distributing electrical energy in a large network. It is one of essential infrastructure in the modern life and should be maintained in high performance. In the event of earthquake, however, this structure may be damaged. This paper aims to evaluate seismic risk of this transmission tower by means of its fragility. An existing tower of 230 kV with 49 m height was 3D modeled in computer with software seismostruct. An incremental dynamic analysis was employed to obtain the structure dynamic performance by using finite element package. Selected ground motion records were matched with and scaled to the target response spectra. Three damage point, namely serviceability (SA), Damage Control (DC) and Collapse Prevention (CP) were then used to state the damage threshold. The fragility function as conditional probability that certain damage state is exceeded given a level of ground motion intensity was the developed for the powerline tower. Expressed as a fragility curve, the function relates earthquake intensities with the probability of exceeding certain limit states. This curve will provide rational basis for evaluating the seismic risk of the infrastructure.
