Numerical Studies on the Damage Locating Vector Approach for Damage Detection Using Static Load Data

Structural Health Monitoring (SHM) is an emerging field in civil engineering, offering the potential for continuous and periodic assessment of the integrity of civil infrastructures. Numerous damage detection methods to identify possible damage locations have been proposed. Most of these methods depend on dynamic characteristics of structure. Damage Locating Vector (DLV) method as suggested by Bernal in 2002[1] has received significant attention because this method was verified by a series of proof-of-concept tests measuring accelerations. This paper presents the details of the numerical studies carried out on the application of DLV method for damage localization using deflection data from static analysis. Several structures includingtrusses and beams were modeled and analysed for various damage scenarios. From the studies it was found that the method was able to identify the locations of damage in most of the cases.
