Galloping in structures
Webof galloping. Since cantilever walk-in overhead Variable Message Sign (VMS) structures are more susceptible to fatigue than span overhead VMS structures, span structures should be used whenever possible. In Florida, changeable or variable message sign structures are typically referred to as Dynamic Message Sign (DMS) structures. Webloping behavior of structures with different cross-sections, such as, rectangular, prismatic, D-section, and triangular. A classic example is the galloping of ice-covered transmission lines. Den Hartog [1] explained the phenomenon of galloping for the first time in 1934 and introduced a criterion for galloping stability of a structure.
