A SI-based algorithm for structural damage detection

Abstract

As a challenging task in the structural health monitoring (SHM) field, structural damage detection, one of most important issues of the SHM system, is mathematically converted into a constrained optimization problem, which is then hopefully solved by a swarm intelligence (SI) based algorithm proposed in this paper. The performance of the proposed algorithm is experimentally evaluated by the measured data of four damage patterns of a building model of 3-storey steel frame structure made in laboratory. Some illustrated results show that the proposed method is very suitable for the structural multi-damage identification, which also show that the SI-based algorithm for structural damage detection can provide an effective and robust tool in the SHM field. © 2012 Springer-Verlag.
