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

This research project investigated cyclical, wind-induced loads on high-mast light towers (HMLTs). Field and laboratory tests were performed to investigate the effects of wind gusts (i.e., buffeting), vortex shedding, and associated dynamic oscillations.

Fatigue Cracking and Inspection of High-mast Lighting Towers

Recent failures of high-mast lighting towers in several states have raised questions as to the robustness and safety of the existing inventory of similar structures. Failure of these structures is very critical as they are typically located adjacent to Interstates or other high-speed highways.
