Abstract
Sectional tests have been performed in a bridge section with an optimized structural configuration. This configuration has been found to be instable at low velocities, suffering both vortex induced vibration (VIV) and flutter. Several relevant parameters of the bridge section and the upcoming flow have been studied, such as the angle of attackof the bridge section, the turbulence of the upcoming flow, the porosity of a central gap and the presence or absence of lower beam. All of them have been found to influence the stability in bending and torsion.In a second campaign, the outer barriers have been removed, but no positive impact has been found.
