Paper Abstract

This paper presents a comparative study of using the modal curvature index and the modal flexibility index for damage localization in the cable-stayed Kap Shui Mun Bridge from the bridge global modal data before and after damage. Based on a precise and validated 3D finite element model of the bridge, a series of damage cases associated with the deck are introduced in the simulation study. They are the damage occurring at the members within deck segments and the damage occurring at the support and bearing system of the deck. The damage indices are applied to determine the specific deck segment that contains damaged member(s).
