Abstract
BEGAMBRE, Óscar; CORREA, Rodrigo and LAIER, José. Damage Detection Using the Modified Residual Force Vector and the Simulated Annealing Algorithm (SA). Rev. ing. univ. Medellín [online]. 2010, vol.9, n.16, pp.25-35. ISSN 1692-3324.
In this research, the Simulated Annealing Algorithm (SA) is employed to solve damage detection problems in beam type structures using noisy polluted modal data. The formulation of the objective function for the SA optimization procedure is based on the modified residual force method. The SA used in this research performs better than the Genetic Algorithm (GA) in two difficult benchmark functions. The proposed structural damage-identification scheme is confirmed and assessed using a Finite Element Model (FEM) of cantilever and a free-free Euler-Bernoulli beam model
Keywords : Damage identification; modified residual force; simulated annealing algorithm.
