| Abstract: | With the Yellow River Mega Bridge of the newly-built Wulashan-Xini Railway as a practical engineering example,the application of viscous dampers to the seismic design of the Yellow River Bridge,which has a main bridge of（65 ＋7×108 ＋65）m,is analyzed and studied in the paper by means of the universal finite element software MIDAS.The research results show that the viscous damper can significantly improve the seismic performance of long-spanned and long-unit continuous girder bridges. |
