Abstract
This experimental work deals with the aerodynamic and aeroelastic behaviour of a full-aeroelastic model of a yawed bridge tower with a “diamond” cross section that tapers off along its height. The results show a significant three dimensional effect on both the aerodynamic forces and wake flow. In addition, a strong turbulence in the oncoming flow reduces the vortex-induced vibration (VIV) response observed in smooth flow but non negligible oscillations still remain.
