Parametric study on flutter derivatives of bridge decks

The method for identification of flutter derivatives of bridge decks develo ped by the authors is first briefly described in this paper. To investigate the effects of dynamic parameters of a bridge deck model on the flutter de rivatives a test of the sectional Jiangyin Bridge deck's models with differ ent dynamic parameters was carried out in a boundary layer wind tunnel usin g the present identification method. In both smooth and simulated turbulent flow conditions, a plate model and the sectional deck model of the Jiangyi n Bridge were tested to further survey the effects of turbulence on flutter derivatives. The identified results tend to indicate that the effects of p arameters of the model and turbulence on the flutter derivatives are neglig ible. (C) 2001 Elsevier Science Ltd. All rights reserved.
