中文摘要	In this paper, a genetic algorithm based method for crack identification is proposed and described, which formulates the crack detection in beam structures as an optimization problem by means of finite element method and utilizes genetic algorithms to effectively search the crack parameters. Due to the nonlinear essence, time response of structural vibration is employed. Numerical simulations have been carried out and the results demonstrate that good predictions of the crack location and magnitude are possible and the proposed method is feasible. The study also indicates that the proposed method has the potential to solve a wide range of inverse identification problems in a systematic and robust way.; Beijing Univ Aeronaut & Astronaut
