Analysis of Across-wind Vortex Shedding Resonance and Its Application to Code

Under wind action, structural vibration occurs not only along wind direction but also across wind direction. In case the vortex shedding frequency is equal to a vibration frequency of structure,extreme vibration of structure occurs, which is very dangerous to structural safety. Based on domestic and international study information and codes, the theory of across wind vortex shedding resonance is introdused and relative clauses of Loading Code is illustrated in this paper. [
