【 摘 要 】

In this paper, a cable-stayed bridge is modelled and analysed using the finite element method on Ansys. The damping effect is studied in the vertical and inclined directions as an earthquake effect is applied on the cable-stayed bridge in the longitudinal and lateral directions with changes to the number, direction, and value of the damping coefficient (c) of the dampers. The results show that increments in the number of dampers and damping coefficient in inclined dampers were more effective than changes to vertical dampers in longitudinal and lateral earthquakes.
