Practical experiences with wind-induced vibrations

Abstract A refined engineering model for the estimation of vortex-induced vibrations slender stuctures is briefly presented. Experiences with this model in relation to full-scale observations are shown within three different examples. The first example is related to steel stacks, the second describes the experience with bridge hangers and its modification by aerodynamic devices. The third example shows the failure of a steel bridge bracing by vortex-induced vibrations and the increase of damping with dynamic vibration absorbers.
