Estimation the structure on galloping fluctuation possibility (rus)
Galloping is self-oscillations of elastic system in wind flow (aeroelastic vibrations). The galloping should be taken into account when designing different structures (pipes, masts, power lines, high-rise buildings, bridges). Existing calculation methods are difficult to realize.Generalized Glowrt-D...
