In applying inelastic or Limit Design procedures to structural frameworks/ the most important critical section is generally the beam support section. The primary objective of this thesis was to study the behaviour of the various experimental models used to simulate the reinforced concrete beam-column connection. With the system itself the main variable/ a series of 33 tests, 12 of which were 2-span continuous systems, was carried out. Additional variables in this essentially qualitative study were: the amount of tension reinforcement, tie spacing, type of loading, the presence of a column, and column load. All tests were deformation controlled in a "stiff" servo-mechanical structural test facility. Post-yield strength and deformation for all systems were evaluated for the more significant semi-empirical approaches. Comparisons were also made with analytical procedures which incorporate recently developed comprehensive stress-strain relationships for reinforced concrete in flexural compression. A generalised expression for post-yield behaviour has been suggested which acknowledges the significance of the cored compression area, the discontinuous nature of deformation and the existence of non-flexural effects. Pre-yield deformation was used as a basis for classifying the experimental models into flexural, non-flexural and quasi-flexural systems
