EFFECTS OF WIND FORCES AND VIBRATIONS ON SIGNS

In an effort to determine the parameters for an optimum sign design that will resist fatigue type failures, the fatigue damage that results from a large number of stress cycles executed by a sign from wind induced vibration was studied. The study which was restricted to single posted (column) signs, focussed on the sign face rather than the post. The parameters considered in the study were: the use of miscellaneous hardware such as washers and back-up plates; initial torque level of mounting bolts; sign face thickness; alternate posts; and alternate fasteners. The investigation involved the determination of the dynamic loading effect that the wind exerts on the various sign styles, followed by the experimental determination of the fatigue strength of the various sign systems as they are subjected to mechanical loading which attempts to simulate various wind loading conditions.
