Fatigue Testing of Ring-Stiffened Traffic Signal Structures: FHWA-WY-08/05F
Based upon in-service inspection of pole with traditional designs, Wyoming DOT’s inventory exhibited approximately a one-third cracking rate. A ring-stiffened connection is presently used. Sixteen fatigue tests were performed on twelve ring-stiffened cantilevered traffic signal pole connections to quantify the fatigue resistance. Two poles sizes we...
