Abstract

The Stress Influence Line (SIL) based damage indices are proposed, and its preliminary sensitivity analysis is applied to a long suspension bridge in this study. Based on Finite Element Model (FEM) of the Tsing Ma Suspension Bridge, hypothetical damage scenarios in which one or two critical bridge components subject to severe damage are simulated. The comparison result suggests that SIL indices from different bridge components surrounding structural damages have different sensitivity to damage. Besides, the sensitivity study also shows that the first-order difference of SIL change is an accurate indicator of the damage location.
