Abstract

Cross-ties have often been used as a passive mitigation system for wind- and rain-wind-induced vibrations of stay cables on cable-stayed bridges. Recently, dampers have also been incorporated in cable networks formed using cross-ties in the hope of combining the mechanisms of both systems, and to achieve improved mitigating performance. This paper presents the results from a recent study conducted to investigate the effectiveness of cross-tie and damper-cross-tie systems of various configurations. This investigation, which is based on both analytical formulation and full-scale measurement, represents a step toward the development of guidelines for the design of cable-networks for stay cable vibration mitigation.
