A Framework for Vibration Attenuation in Traffic Mast Arm Structures under Wind Loads

Traffic signals and information signs play a vivid role in maintaining safe travel by guiding drivers on highways urban roads. mast arm structures are susceptible to vibrations induced wind loads. Fatigue-induced failure is common these structures. However, it crucial ascertain the functionality of signal support This paper lays foundation for fully computational framework model mitigate wind-induced traffic lighting conducting fluid dynamics (CFD) simulations, dynamic modeling, damping enhancement. We validated CFD simulations aerodynamic testing. The dependence flow pattern loads Reynolds number reveals importance full-scale with large eddy simulation load estimation Distributed tuned mass dampers were created employing available weights boxes. results show that distributed boxes effective vibration suppression. Besides, enhancement can significantly reduce vibration-induced stresses hence extend fatigue life. proposed mitigation technique promises save construction costs improve safety traveling public. procedure followed creating time histories integrated finite element modeling applies other lessening techniques potential inclusion AASHTO standard.
