Abstract
The type of bridge structure for the main bridge of Yellow River extra-long bridge on Wu-Xi railway is a large cross-span continuous beam bridge with huge mass superstructure. The seismic fortification is the key technology of this project. In this paper, a spatial finite element model is built with Midas/civil and three seismic waves suitable for site grade and seismic characteristics of bridge site are selected. The anti-seismic effect of the fluid viscous damper device installed between the non-fixed pier and the main beam is calculated with nonlinear time history analysis method. By setting up fluid viscous damper between the non-fixed pier and the main girder, the non-fixed pier is effectively coordinated under the dynamic action, and the seismic force of the fixed pier is reduced. The seismic fortification standard of the main bridge is effectively improved.关键词
