Sažetak
The main advantage in identification of modal parameters using only response (output-only) measurements is that we don’t need to know the input forces to the structure. This technique is widely known as Operational modal analysis (OMA) as it uses ambient operating forces, in this case traffic. This paper gives an overview of modal parameters determined on two identical single span bridges using output only measurements and their comparison to numerical results of natural frequencies and mode shapes. Comparison of experimentally determined natural frequencies and mode shapes for two identical bridges shows very good correlation, as well as their comparison to numerical values obtained from FEM model. These results lead to conclusion that high precision of modal parameter estimation was achieved.
