| Abstract: | Research of longitudinal aseismatic performance for a long span railway simply-supported steel truss girder bridge on tall piers with non-linear viscous dampers is presented. Optimum analysis on the position and related parameters of the supplemental non-linear viscous dampers is performed by using non-linear time history response analysis. The results show that if the position, numbers,parameters of viscous dampers are reasonably selected, significant effect of seismic response reduction can be obtained for the long span railway simply-supported steel truss girder bridge on the tall piers. |
