RAMIREZ, Diego; GOMEZ, Iván Darío  and  QUIROGA MENDEZ, Jabid. Structural damage detection using PSO optimization technique. Ing. Desarro. [online]. 2010, n.28, pp.89-105. ISSN 0122-3461.

This paper presents a structural damage detection system. Variations in elasticity module are used as a damage condition in a structural finite element model. This deviation alters vibration natural frequencies and shape modes; which is the fault indicator in this proposal. Noise and incomplete data are used to emulate real conditions in a beam and truss in different fault scenarios. Simulations show satisfactory performance in all cases studied. Therefore, this system can be used as suitable structural damage detection system.

Keywords : Damage detection; finite elements; PSO.
