TESTING OF SIGNS AND THEIR SUPPORTS AGAINST WIND FORCES AND VIBRATIONS

In this investigation of the fatigue failure (fatigue damage being a direct result of the sign being subjected to a large number of stress cycles from wind induced vibrations) of single-posted highway sign faces and their associated hardware, the parameters that will result in an optimum sign design for resisting fatigue-type failures were determined. The parameters under consideration were: the proper use of miscellaneous hardware such as washers and back-up plates, initial torque level of mounting bolts, sign face thickness, and alternate hardware and/or posts. This experimental study consists of 2 parts: the determination of the dynamic loading effect that the wind exerts on different sign face styles attached to various posts; and the evaluation of the fatigue strength of the various signs and their mounting conditions as they are subjected to mechanical loading. Details are described of wind excitation measurements, and the fatigue tests. A significant portion of the results obtained to date are summarized in a graphical figure.
