Semi-active Control of Continuous Girder Bridges Considering the Coupling Effect of Earthquake and Hydrodynamic Pressure

Abstract: Under the action of earthquakes, the dynamic responses of cross-sea bridges are greatly influenced by the dynamic interaction between each pier and the surrounding water. Based on Morison equation, this paper mainly explores the responses of a continuous girder cross-sea bridge in uncontrolled and semi-active control modes, under the combined effect of earthquake and hydrodynamic pressure. First, a simplified two-degree-of-freedom (2DOF) analysis model was constructed for the bridge: the combined stiffness was… Show more

“…With the rapid development of the economy and society in China, tunnels have to be built in areas of high earthquakeintensity where earthquakes frequently occur. Many investigations conducted after earthquakes have occurred indicate that the damage caused to the tunnel lining by a massive earthquake is very serious [1][2][3][4][5], and there are various forms of damage. Anti-seismic design for underground structures mainly concentrates on the following aspects.…”
