RIVEROS JEREZ, Carlos Alberto; GARCIA ARISTIZABAL, Edwin Fabián  e  RIVERO JEREZ, Javier Enrique. A COMPARATIVE STUDY OF SENSOR PLACEMENT TECHNIQUES FOR STRUCTURAL DAMAGE DETECTION. Rev.EIA.Esc.Ing.Antioq [online]. 2013, n.20, pp.23-37. ISSN 1794-1237.

An evaluation of the capabilities and limitations of practical placement techniques used for damage detection in civil engineering structures is performed. Three previously development sensor distribution methods, Eigenvector Sensitivity, Effective Independence, Damage Measurability are compared through numerical studies. The focus of this comparative study is beam-like structures, and two representative examples are considered to evaluate the techniques. The first example considers a single span beam, which could represent a highway bridge. The second example considers a structure with intermediate supports, and could represent the entire deck of a long-span bridge. Due to its successes in previous studies, the Bayesian Probabilistic Approach is employed to identify, locate and quantify damage using the resulting sensor measurements. The impact of noise in the modal parameters is considered. The effectiveness of the resulting sensor configurations for accurately identifying damage scenarios is assessed.

Palavras-chave : Sensor Placement; Structural Damage Detection; Bayesian Probabilistic Approach.
