Abstract

We present a new strategy for applying to CONTINUOUS GENETIC ALGORITHM for damage detection of structures. This strategy pursues two aims: 1) reducing search space by elimination of some design variables during optimization process, 2) improving each individual by solving the linearized problem using Moore-Penrose pseudo inverse at the end of reproduction of genetic algorithm. To these ends, two sub-programs are embedded after typical GA operators. This strategy is applied to three different types of problems: damage detection by frequencies and by static measurements, and crack identification of a beam using frequencies. Numerical results demonstrate the high efficiency of the proposed algorithm compared to those found in the literature.
