| Abstrakt: |
The paper presents an investigation on the accuracy of a sophisticated system identification technique in providing the modal parameters of wind-excited suspension bridges, using pseudo- experimental data. The aim is to quantify the bias produced by colored wind excitations, measurement noise and wind-structure interaction effects on the modal parameter estimates. In addition, as the accurate estimation of structural damping ratios is a priority for safety evaluations and structural health monitoring of long-span bridges, a particular attention is posed on the feasibility of the considered system identification technique for separating structural from aerodynamic damping. |
