| Abstrakt: |
A unified approach for the aeroelastic analysis of bridge decks is presented. The aerodynamic transfer functions are approximated as a linear function with the coefficients determined through minimization of the weighted error between the exact and approximated transfer function. Using the proposed approximation, the dependence of the aerodynamic transfer function on frequency is eliminated, and a popular time marching algorithm is adopted for the aeroelastic analysis in the time domain. For the frequency domain analysis, a complete set of modal frequencies and modal shapes can be evaluated in a single eigenvalue analysis. |
