| Abstract: | To improve the seismic performance of isolated bridge subjected to near-fault earthquakes,benchmark structural vibration control for a seismically excited highway bridge is used as a numerical example to demonstrate the effectiveness of the hybrid isolation system with viscous damper and magnetorheological(MR) damper.In the process of nonlinear dynamic analysis,the damping coefficient and velocity index of viscous damper are optimized,and the decentralized fuzzy logic control method is employed to determine... |
