Abstract

In order to investigate the simplified design method for damper installed on cable-stayed bridge in near-fault zones, this paper proposed two-particle model for cable-stayed bridge and established the differential equations of motion. Parameter design formula for linear viscous damper is derived based on the concept of equivalent damping ratio, parameter design formula for nonlinear viscous damper is also deducted by equivalent linearization method. In the end, a single tower cable-stayed bridge is cited to verify accuracy of the formulations.
