The criteria for joints classification are well defined but it is then left to designers to assess the effect of joint rotation on the overall structural response of a framed system. It seems thus necessary to define in a very short time, the criteria and prediction methods that permit the use of a structural solution with semi-rigid joints in current practice. For this purpose, a research project has been conduced in Belgium, Great Britain and Italy. Italian research focused on beam-to-column joints of framed system with cold-formed members and on steel-concrete composite frames. The English group studied the stability of tridimensional steel frames and the Belgium research group directed their activities towards the study of structural system in hot-rolled members. The overall research plan, as reported in the enclosed flow charts, involves the following steps: definitions of the state of the art of the experimental research on the behaviour of semi-rigid joints; identification of the forms of beam-to-column joints of greatest significance for civil buildings; designing of joints for full scale experimental tests; performing experimental tests to highlight the key characteristic behaviour of models subjected to monotonic and cyclic loads; development and calibration of models for the simulation of the joint response; structural analyses of composite frames and frames in coldformed members under seismic actions.
