[S01B-01] Investigations of optimal sensor position for detecting transmission tower damage

Keywords:transmission steel tower, acceleration wave, acceleration sensor

In recent years, the scale of transmission tower patrol and inspection work has been gradually reduced due to personnel or cost reduction. Therefore, in case if tower malfunction happens, it is inevitable that we need more time to discover the problem. Authors suggest the method to monitor from features of the acceleration wave pattern. The purpose of this paper is to report the result of simulating earthquakes and sleet jump and then estimate the most suitable position for the sensor by analyzing the obtained response waveform.
