| Abstract: | Based on the vibration characteristics of the existing half-through steel truss bridges,this papere stablishes equations for the lateral vibration of the Bridge-Vehicle-MTMD coupling system.A plan is devel-oped to control the lateral vibration amplitude of the lower chord at the mid-span of a steel bridge with the FMmass dampers.The feasibility of the lateral vibration suppression is analyzed using the simulation program.The results showthat the damping effects of the TMD on the suppression of vibration for half-through steel truss bridges are significant. |
