In steel frames, it is usually the minor-axis beam-to-column connections that govern restraint to the columns against buckling. There is, however, no generally accepted method to predict the behaviour of such connections. To clarify the response, a series of tests have been performed, in which significant parameters have been systematically varied. The results have been used to train an artificial neural network (ANN) to predict bi-linear moment-rotation characteristics for minor-axis connections. The paper describes the test programme, the choice of ANN and the result for each connection, based on learning from 20 other connections. The results are found to provide approximations to the experimental response that are satisfactory for use in structural engineering design.
