What is Investigation of dynamic cable-deck interaction in a physical model of a cable-stayed bridge. Part II: seismic response about?
The present paper describes an investigation of the e!ect of dynamic cable interaction with the deck and towers in the seismic response of a cable-stayed bridge. This study involved shaking table tests performed on a physical model of Jindo bridge, in order to validate two alternative numerical models, which di!er in terms of consideration of coupled cable/deck and towers modes. The response to arti"cial accelerograms was calculated and correlated with measured data. Additional numerical simulations are presented in order to clarify the role that cables play in the attenuation or ampli"cation of the structural response. It was found that the cable interference with global oscillations may cause a decrease of the bridge response. However, this &system damping' may not develop in the case where a narrow-band excitation is applied, causing large amplitude of vibrations of some cables, with signi"cant non-linearity, and inducing higher-order modes.
