Development of Fatigue Loading and Design Methodology for High-Mast Lighting Poles

Recent failures of high-mast lighting poles in several states have raised questions as to the robustness and safety of the existing inventory of these structures. Fatigue failures have occurred at the base plate-to-column weld, handhole detail, and anchor rods. Several of the failed poles had been in service for less than 5 years. Based on field observations and forensic analysis of high-mast lighting poles, it is believed that wind-induced vibrations have a significant influence on the fatigue life. Neither the magnitude of the loads or the frequency of the application is understood. The current American Association of State Highway & Transportation Officials (AASHTO) specification does not adequately address these topics. Research is needed to define the fatigue loading for the safe design of high-mast lighting poles. A design methodology and specification with the associated commentary also is needed. The objectives of this research are to develop (1) loading and analysis criteria for use in the fatigue design of high-mast lighting poles and (2) a design method and specifications for high-mast lighting poles.
