At the first stage, the moment-rotation law of the connection is obtained from experimental results by the use of a neural network based on the perceptron model. At the second stage, the elastoplastic analysis problem is formulated for the given moment-rotation law as a Quadratic Programming Problem and solved by a neural network based on the Hopfield model.http://creativecommons.org/licenses/by/4.0/Journal of Constructional Steel Research1-24491-105 Panagiotopoulos, P.
