Aerodynamics and Aeroelasticity of Cable-Supported Bridges: Identification of Nonlinear Features
Publication: Journal of Engineering Mechanics
Volume 139, Issue 12
Abstract
Modern bridge decks exhibit nonlinear behavior in wind tunnel experiments; this has placed increasing importance on nonlinear bridge aerodynamics/aeroelasticity considerations for long-span bridges. In this context, various observed nonlinear phenomena in wind tunnels are discussed, and their identification through high-order spectrum is illustrated.
