In order to present fragility analysis, the present research has offered the implementation of Neural Network (NN), which can give accurate estimations of structure responses in a part of the required calculated time by common analysis. The main advantage of using Neural Network (NN) concept is that it can study the issues without having an algorithmic solution or one which is quite hard to find. The proposed methodology has been used for steel moment frame structures. Results show that by implementing the proposed Neural Network (NN), a reduction of one-order magnitude is obtained to have a complete fragility analysis.
