Abstract and Figures Seismic risk and sustainability goals are often at trade-off when performing structural optimisation of cable-stayed bridges.
While previous studies have primarily concentrated on super-span cable-stayed bridges under mild to moderate seismic conditions, this work delves into the dynamic response of super-high
This work focused on the damping effectiveness of additional longitudinal viscous dampers employed for seismic control of long-span cable
The seismic damages of these cable-stayed bridges have been judiciously reviewed and discussed in a recent work (Yi et al., 2020) to point out that they share a common damage feature in
A representative medium-span concrete cable-stayed bridge is taken as an example, this study will firstly compare the seismic response of the bridge
Seismic behavior of different cable‐stayed bridge systems is then evaluated via shaking table tests under different ground excitations. Experimental results show the effectiveness of the SCD.
Using the optimum parameters of damper, the height of pier under tower and intermediate supports in side span on seismic responses are studied in detail.
Thus, in this paper the seismic behavior of cable-stayed bridges are investigated and compared due to different conditions of cable''s placement forms.
Most of them are footbridges, but the number of road and railway applications is increasing. However, there is not much information concerning the design of these structures. This
Then the seismic responses of a case cable-stayed bridge are investigated under near-fault ground motions. It reveals that both the external vibrations and parametric vibrations might
Due to their light weight and low inherent damping, cable-stayed bridges are vulnerable to earthquakes and significant damages to the deck-to
