Seismic Vibration Control of Izad-Khast Bridge Using Viscous Dampers
Abstract eng: Present study addresses the effectiveness of viscous dampers (VDs) in reducing the response of Izadkhast Bridge under earthquake ground motions. With the length of 485 m, Izadkhast Bridge is the longest box girder bridge in Iran and is located in Isfahan-Shiraz railway. The bridge is installed with VDs at the two ends. The Finite element model of the bridge is developed. Five pairs of representative earthquake records are selected and scaled using the earthquake code and applied to the model. Nonlinear seismic analyses of the structure without and with VD's are performed and the results are reported. Comparison of the results clarifies VD's effectiveness on seismic response reduction of the bridge. Sensitivity analyses are performed to demonstrate the effects of damper parameters on structural response.
