• Evaluation on seismic performances of railway bridges applied the passive negative stiffness friction dampers

抄録

The authors have proposed a “passive negative stiffness friction damper” for the purpose of the seismic performance improvement of the railway bridges. In this study, we examined the applicability of the proposed devices to the railway bridges by the parametrical analysis with simple models, the trial design and the dynamic interaction analysis for railway vehicles and bridges. As a result, we have confirmed that the devices are effective in the reduction of the structures response and the improvement of the vehicles running safety on the bridges during the earthquake by adjusting the stiffness of the devices to the value from -0.5 to -0.3 times as large as the equivalent stiffness of the rubber bearings.
