| Abstract: |
| In this paper, the application and development of neural network in structure dynamics analysis are reviewed, the fast learning algorithm and samples selection method by orthogonalization for BP neural network are presented, which can improve the convergence speed of neural network and decrease greatly quantities of training samples required in engineering practice. Some particular problems in implement of neural network such as design of network topology, normalization of training samples, adaptive modification of computing results are discussed in detail and solved satasfactorily. At last, two engineering application examples are given and results are promising. |
