Synchronous Optimization of Key Parameters of Transverse Seismic Isolation System for Asymmetric Cable-stayed Bridge with Unequal Height Towers
The influence of key parameters of transverse seismic isolation system, which consisted of steel dampers and wind bearings, on transverse seismic response of cable-stayed bridges is investigated in this paper. An asymmetric cable-stayed bridge with unequal height towers is taken an example bridge, and orthogonal test design method is used to set test conditions for synchronous optimization of the key parameters. The results show that significant parameter coupling is observed from internal force of auxiliary pier and left deck end displacement, so synchronous optimization should be considered. Moreover, steel dampers have little effect on the internal force of towers while internal force of auxiliary pier and deck end displacement can be significantly decreased by setting steel dampers.
