Abstract

This paper investigates the mechanism behind the wind-induced vibration of high mast illumination pole (HMIP) structures using wireless smart sensors. Several video recordings revealed significant vibrations of an HMIP under wind loading in Kansas, resulting in large cyclic displacements. In this study, to facilitate the estimate for the main cause of the HMIP’s vibration, finite element modeling and video analysis are employed to evaluate the fundamental natural frequencies and the recorded vibration frequencies of the HMIP of interest. Meanwhile, a 100-foot-tall, galvanized steel HMIP with three LED luminaires is selected for long-term vibration monitoring. A wireless smart sensor network is designed to monitor the structure's acceleration response, wind speed, and wind direction to further investigate the primary cause of the excessive wind-induced vibrations.
