โœฆ Synopsis

A new passive aerodynamic control method is proposed. The system uses TMD mechanism to activate the control plates, which modify air#ow around the deck to stabilize bridge motion. The e!ectiveness of the proposed model is veri"ed experimentally and analytically. Additionally, various parameters of the proposed system and applicability to a long span bridge were investigated. Based on the investigation, it is found that the proposed model is very e!ective in suppressing #utter. In the analytical results, the model also shows remarkable robustness against variation of structural properties.

## Abstract The problem of efficiently approximating real frequency data, which represents either measured information of a physical system or idealized curves to be realized by rational positive real (PR) or bounded real (BR) functions is considered. The final rational function is guaranteed in ad
