Impact of Key System Parameters on the In-Plane Dynamic Response of a Cable Network
Publication: Journal of Structural Engineering

Abstract
Using crossties to connect a cable which has experienced or is prone to violent motions with its neighbors and form a cable network has been successfully applied to a number of cable-stayed bridges to control stay cable vibrations. However, matured guidelines for designing crossties are still lacking. The present study aims at identifying key system parameters which dictate the in-plane dynamic behavior of a cable network and evaluate their respective roles. An analytical model of a general cable network consisting of horizontally laid cables interconnected by a single line of transverse rigid crossties will be developed, based on which the key system parameters will be identified from the system characteristic equation. An extensive parametric study will be conducted to assess the impact of these parameters on the dynamic response of cable networks. The outcome from the study is expected to not only comprehend our understanding in the mechanics associated with cable networks, but also shed light on developing more effective and creative crosstie solutions.
