- Summary:- This Lecture is relevant to IABSE SED 9 by Dr. E. Caetano, It describes the dynamic tests performed on Vasco da Gama cable-stayed bridge so as to accurately identify its most significant modal parameters from the aerodynamic and seismic point of view. The main results obtained on the basis of ambient vibration and free vibration tests are presented and correlated with the corresponding parameters provided by the finite element model developed at the design stage. Moreover, the usefulness of application of a laser Doppler sensor to perform dynamic measurements on a large number of stay cables is also stressed, as well as the feasibility of experimental evaluation of dynamic amplification factors associated to the passage of heavy traffic.
