Design and performance evaluation of tie-down cables for mitigating seismic uplift in cable-stayed bridges

Key Points

• Mitigating seismic uplift effectively enhances the stability of cable-stayed bridges.
• Performance evaluations demonstrate that tie-down cables can reduce uplift forces by up to 30% during seismic events.
• Design optimizations include alterations to the cable configuration for improved performance.
• The findings may guide future engineering practices to enhance bridge safety during earthquakes.
