In this study, the artificial neural network (ANN) based estimation method for rotational stiffness of column-beam connection in steel moment frames is presented. Three story and one bay steel moment frame is used as the example structure. Natural periods and mode-shapes are used as the input data and the rotational stiffness values of connections are used as the output data.
