Modelling of nonlinear bridge aerodynamics and aeroelasticity: a convolution based approach
Nathaz Modeling Laboratory, University of Notre Dame, Notre Dame, IN 46556, USA
Innovative bridge decks exhibit nonlinear behaviour in wind tunnel studies which has placed increasing importance on the nonlinear bridge aerodynamics/aeroelasticity considerations for long-span bridges. The convolution scheme concerning the first-order kernels for linear analysis is reviewed, which is followed by an introduction to higher-order kernels for nonlinear analysis. A numerical example of a longspan suspension bridge is presented that demonstrates the efficacy of the proposed scheme.
