The objective of this paper is to investigate the efficiency of soft computing methods, in particular methodologies based on neural networks, when incorporated into the solution of computationally intensive engineering problems. Two types of applications have been investigated, namely flaw identification and structural reliability analysis. Artificial neural networks (ANNs) based metamodels are used in order to replace the time-consuming repeated structural analyses. The back propagation algorithm is employed for training the ANN, using data derived from selected analyses. The trained ANN is then used to predict the values of the necessary data. The numerical tests demonstrate the computational advantages of the proposed methodologies.
