A number of approaches are available for design of beam-column joints. The joint details resulting from the application of each approach differ considerably. In most cases the transverse reinforcement required in the joint is substantial and makes fabrication difficult. The requirements for transverse reinforcement can be traced to the research which forms the basis for design rules. In many cases the loading histories used in test programs produce very large deformations which may be in excess of the deformation realized in actual structures. Research on beam-column joints is reviewed and suggestions are made for determining loading histories and test specimens which may be more rational in terms of structural performance requirements.
