A backpropagation neural network model for semi-rigid steel connectionsA backpropagation neural network model for semi-rigid steel connections Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-111995enThe analysis of semirigid steel structure connections based on exact theoretical modeling, which is demanding and time consuming if all the nonlinear parameters of the problem are taken into account, can be avoided provided that enough experimental measurements exist and an appropriate predictor can be constructed from them. A supervised learning backpropagation neural network approach is proposed in this paper for the construction of this model free predictor. A number of experimental momentrotation curves for single-angle and single-plate beam-to-column connections are used in this paper to train the neural network. The trained network provides us with an estimator for the mechanical behavior of the steel structure connection element.http://creativecommons.org/licenses/by/4.0/Computer‐Aided Civil and Infrastructure Engineering 21077-87 Stavroulakis Georgios Σταυρουλακης Γεωργιος K.
