Abstract

A bridge structure may sustain damage either when subjected to severe loading like a strong earthquake or when its material deteriorates. Monitoring the structural health of a particular structural system involves a damage identification process that comprises detecting, locating, identifying type of, and estimating severity of, damage. The aim of this paper attempts to utilize frequency response function (FRF) as index in SHM for locating and estimating severity of damage to bridge structures. First, a numerical study, based on SAP2000 software, is employed to create simulated damage cases including single and multi-site(s) damage scenarios. Following, a novel FRF curvature method is developed and applied to locate damage. The simulation and experiment results expose that the proposed FRF index can locate damage correctly in single as well as multi-site(s) damage acceptably.
