| In order to mitigate tsunami effect on bridge structures， tsunami induced forces are needed to be understood and countermeasures for reducing these forces are also required to be established. In this research， a countermeasure by means of installing a fairing on the side surface of superstructure was studied with purpose to reduce tsunami induced forces acted on superstructure. Influences of fairing shape on hydrodynamic forces were investigated based on hydraulic flume tests. It is confirmed that fairing can provide well reduction effect on hydrodynamic forces including surge force and drag force. |
