CALCULATION OF FREQUENCY OF RETAINING WALL BY BACK PROPAGATION NEURAL NETWORK

A method is used to obtain the fundamental frequency of a retaining wall quite accurately and carry out a dynamic analysis of such wall based on modal response technique. The present procedure establishes both the general and particular cases of dynamic response of retaining wall based on improved Rayleigh-Ritz method. The wall will be assumed to be a flexural member. The fundamental frequency of the retaining wall with soil mass has been computed. The results based on proposed method are then used to back propagation neural network (BPN). In the present work, the fundamental frequency of a retaining wall is calculated by BPN. A significant benefit of BPN is its ability to learn relationships between variables with repeated exposure to those variables. Therefore, instead of deriving an analytical relationship from mathematical formulations, the BPN learns the relationship through an adaptive training process. Numerical example shows the merit of the BPN.
