Enhancing seismic performance of cable-stayed bridges using tuned mass dampers

الملخص EN

Enhancing the seismic performance of cable stayed bridges (CSBs) gained increasing attention over the past few decades.

the aim of this paper is to investigate how single tuned mass damper (TMD) can enhance the performance of CSB by comparing the performance of the CSB before and after incorporating the TMD under different excitation records.

finite element analysis has been performed and verified in order to assess the optimum value of TMD mass ratio.

results show that, the presence of TMD leads to a noticeable improvement in different responses.

also, for mass ratio values between 0.25% and 0.5%, the bridge shows best performance.
