| Abstrait: |
This paper aims to mitigate the seismic pounding effects on an existing steel cable-stayed bridge through the implementation of metallic dampers. The earthquake-induced pounding phenomena were reported on the bridge in 1988. To aid the aim, a finite element model of the bridge is created and the nonlinear time-history is performed to assess the impact of the proposed control system on the bridge seismic performance. Results of the comparative study showed that the seismic pounding significantly mitigated by metallic dampers and the global seismic responses of the bridge enhanced, relatively. |
