Abstract
The dynamic behavior of a complex bridge, whose skew deck is supported by 18 cables suspended by a twinarches frame, has been analyzed. The bridge is 110 m long and 14.80 m wide. Dynamic tests were conducted in operational conditions to estimate the modal properties. Up to the first twenty vibration modes were identified. Additional impulsive tests were carried out to identify the frequencies of the cables. The numerical part of the investigation involves the calibration of a FE model and the identification of axial force in the staysFile in questo prodotto:
