Seismic mitigation and isolation analysis of continuous curved beam bridge with different height piers

JIANG Linjun;LI Zhengying;WANG Zeguo;Civil Engineering College of Chongqing University;  
The model of this article is from a real project,but it is only a part of the whole bridge. It is a continuous curved beam bridge whose radius is 250 meters. This part in the article has different piers and the highest pier is 40 meters. The analysis program of this article is SAP2000 FNA( non-linear modal time history analysis). There are five cases which include original structure,structure with lead-rubber bearing,structure with viscous fluid damper,and two combined isolations of lead-rubber bearing and viscous fluid damper. The results of these analyses show that the combined isolation whose lead-rubber bearings and viscous fluid dampers are properly paced is the best way for this kind of curved bridge.
