The problem of structure damage identification based on combination of genetic algorithms and neural network is studied. Firstly we present the necessity and availability of combining the neural network and genetic algorithm to solve the problem of nonliearity and uncertainties.Then study the possibility of solving the problem of structure damage with this model.The simulating results show that extensive mapping ability of neural network and rapid global convergence of genetic algorithm can be acquired by combining them.
