Abstract EN
This paper describes the results of a model updating study conducted on a historical aqueduct, called Veziragasi, in Turkey.
The output-only modal identification results obtained from ambient vibration measurements of the structure were used to update a finite element model of the structure.
For the purposes of developing a solid model of the structure, the dimensions of the structure, defects, and material degradations in the structure were determined in detail by making a measurement survey.
For evaluation of the material properties of the structure, nondestructive and destructive testing methods were applied.
The modal analysis of the structure was calculated by FEM.
Then, a nondestructive dynamic test as well as operational modal analysis was carried out and dynamic properties were extracted.
The natural frequencies and corresponding mode shapes were determined from both theoretical and experimental modal analyses and compared with each other.
A good harmony was attained between mode shapes, but there were some differences between natural frequencies.
The sources of the differences were introduced and the FEM model was updated by changing material parameters and boundary conditions.
Finally, the real analytical model of the aqueduct was put forward and the results were discussed.
