Abstract

This dissertation investigates the effects of ice accretion on the aerodynamics and aeroelastic stability of bridge hangers and stay cables. First, a review of the state of art on the aerodynamics of nominally circular cylinders is given. Then, the aerodynamic behavior and accretion characteristics of ice accreted bridge cables were experimentally studied by climatic wind tunnel tests. The aerodynamic stability was investigated using the models proposed by different authors. Furthermore a novel 3D 3-DoFs quasi-steady aeroelastic model is proposed.
