Effect of Wind Induced Unsteady Vortex Shedding, Diurnal Temperature Changes, and Transit Conditions on Truss Structures Supporting Large Highway Signs
The Iowa Department of Transportation has released a report that estimates the unsteady wind loads acting on dynamic message signs and on the members of the truss structures supporting these signs. This report also identifies possible fatigue failure due to vibrations, and investigates diurnal temperature effects on the fatigue life of structures.
