ABSTRACT
The behaviour of plane-or space frames may be analysed by means of computer programs. Some of the latter can account for the semi-rigidity of the beam-to-column joints. For beams (fig. l.a) that are connected to the column flanges (strong axis connection), the information regarding the behaviour of the joints is available. It is largely missing when the beam (fig. l.b) is connected to the column web (weak axis connection) [I] [2]. The question is still more intricate when 3-D joints (fig. I.e) because of the interaction in the column web between both strong-and weak axis connections [3]. With a view to collect some data on weak axis-and 3-D connections, some tests were carried out at the University of Liege. It is only reported on those, the results of which have already been fully investigated.
