Original Abstract

This paper describes the use of a metaheuristic optimization method aimed multilevel sampling to efficiently search the design parameter space in order to achieve the best match between the deformed structure and its model. The presented methodology is applied to damage identification of single- and double-span steel trusses. The effect of the damage rate and location on the identification speed and the accuracy of the solution is investigated. In all studied cases, damage was identified with acceptable accuracy.

Keywords

Model updating, damage detection, modal properties, metaheuristic optimization, aimed multilevel sampling.
