Effect of Viscous Damper Position for Isolation System of Self-Anchored Cable-Stayed Suspension Bridge

Abstract:

Larger displacement and inter-force response of the structure will be produced when self-anchored cable-stayed suspension bridge in longitudinal earthquake. For the isolation system of self-anchored cable-stayed suspension bridge, whose main tower is set the lead core rubber isolation bearing. This essay does the nonlinear time history analysis under the longitudinal earthquake about the isolation system when the viscous damper is put in different location. Analysis results show that inter-force and displacement of control section and control node are reduced greatly in hybrid vibration control. The result is obvious when the viscous damper is set both in the main tower, the side block and only in the main tower.
