A new passive aerodynamic control method for bridge flutter

A new passive aerodynamic control method is proposed. The system uses TMD m echanism to activate the control plates, which modify airflow around the de ck to stabilize bridge motion. The effectiveness of the proposed model is v erified experimentally and analytically. Additionally, various parameters o f the proposed system and applicability to a long span bridge were investig ated. Based on the investigation, it is found that the proposed model is ve ry effective in suppressing flutter. In the analytical results, the model a lso shows remarkable robustness against variation of structural properties. (C) 2000 Elsevier Science Ltd. All rights reserved.
