This paper presents a general framework for the evaluation of the aeroelastic response of a complex slender structure with generic cross sections. First, the Rayleigh–Ritz approach and the Lagrange equation are employed to describe the vibrations of...

Galloping analysis of a stay cable with an attached viscous damper considering complex modes (2017)
Journal Article
Nguyen, C., & Macdonald, J. (2018). Galloping analysis of a stay cable with an attached viscous damper considering complex modes. Journal of Engineering Mechanics, 144(2), 04017175. https://doi.org/10.1061/%28asce%29em.1943-7889.0001403

The use of viscous dampers to mitigate cable vibrations on cable-stayed bridges is very popular. A viscous damper attached to a stay cable results in complex mode shapes. Such complexity could affect the dynamic stability of the cable under wind acti... Read More about Galloping analysis of a stay cable with an attached viscous damper considering complex modes.

Galloping of an elliptical cylinder at the critical Reynolds number and its quasi-steady prediction (2017)
Journal Article
Ma, W., Macdonald, J., Liu, Q., Nguyen, C., & Liu, X. (2017). Galloping of an elliptical cylinder at the critical Reynolds number and its quasi-steady prediction. Journal of Wind Engineering and Industrial Aerodynamics, 168, 110-122. https://doi.org/10.1016/j.jweia.2017.04.022

Dry galloping of inclined cables has been shown to have a strong relation to the critical Reynolds number. This study considers the occurrence of galloping of an elliptical cylinder at the critical Reynolds number under normal wind and assesses the q...

Experimental investigation of the aeroelastic behavior of a complex prismatic element (2015)
Journal Article
Nguyen, C., Freda, A., Solari, G., & Tubino, F. (2015). Experimental investigation of the aeroelastic behavior of a complex prismatic element. Wind and Structures, 20(5), 683-699. https://doi.org/10.12989/was.2015.20.5.683

Lighting poles and antenna masts are typically high, slender and light structures. Moreover, they are often characterized by distributed eccentricities that make very complex their shape. Experience teaches that this structural type frequently suffer... Read More about Experimental investigation of the aeroelastic behavior of a complex prismatic element.
