Abstract:

Under the excitation from wind, some highway lighting poles have exhibited large-amplitude vibrations. Such unexpected vibrations have resulted in premature failure of, or damage to, these structures. To investigate the mechanism of these wind-induced vibrations, a long-term full-scale measurement project was conducted at Texas Tech University under the sponsorship of Texas Department of Transportation. Interpretation of the recorded lighting pole vibrations and the corresponding wind revealed two types of wind excitation mechanism: buffeting, which is responsible for large-amplitude vibrations in the first in-plane and out-of-plane modes of the structure, and vortex-shedding, under specific wind conditions, which induces vibrations of the structure in the higher modes. This report describes the full-scale monitoring campaign and summarizes the results obtained from this effort.
