Research on Dynamic Characteristics and Seismic Energy Dissipation of Semi-floating Cable-Stayed Bridges
In order to study dynamic characteristics of a semi floating cable-stayed bridge,the paper studies itsseismic response.The study showed that the basic mode of the semi floating cable-stayed bridge is longitudinal float-ing,and under seismic action,there will be significant longitudinal displacement at the beam end and tower top.The use of metal dampers can significantly reduce the displacement response of the tower top and beam end along the bridge direction.
