Seismic Response Mitigation of a Long-Span Tower Bridge with Two Types of Constraint System by Li Xu, Qingfei Gao, Junhao Zheng, Chuanhui Ding, Kang Liu

“…Without considering the influence of the transverse constraint, the damping effect of the elastic connection device and the viscous damper is simulated when the longitudinal seismic load is input. The results show that the stiffness of the main beam is increased by installing the elastic connection device, so the longitudinal drift frequency of the main beam is increased, but the stiffness of the structure is not changed by installing the viscous damper. …”
