Paper Title:
Comparative Study on Schemes of Seismic Response Reduction for the Railway Extradosed Cable-Stayed Bridge
  Abstract

Based on mechanical properties of railway extradosed cable-stayed bridge with the rigid continuous beam system in the high-intensity earthquake zone, three kinds of scheme on seismic response reduction including viscous dampers, lock-up device and friction sliding bearings is presented in the text and effectiveness of seismic response reduction is analyzed by using non-linear time history response analysis . The results show that three types of isolation devices are significantly effective for improving seismic performance of the railway extradosed cable-stayed bridge. Seismic response reduction of viscous damper and Lock-up device is better, that of friction sliding bearing is second. but the type of viscous dampers is most optimal considering from normal use for structure and distribution of the seismic response in the structural system.
