Traffic signal supporting structures and methods
Abstract
The embodiments presented herein include systems and methods for mitigating fatigue and fracture in mast-and-arm supporting structures caused by wind and other excitation forces. In particular, the embodiments presented herein utilize pre-stressed devices to reduce tensile stresses in arm-to-mast connections and/or mast-to-foundation connections of the traffic signal supporting structures. Present embodiments may employ stressed cables, post-tensioned bars (e.g., DYWIDAG bars), threaded rods, and so forth, to mitigate fatigue and fracture in the traffic signal supporting structures.
