The paper describes the testing of three reinforced concrete haunched beam-column assemblies under incremented-static cyclic loading. The half or full size test units were based upon typical interior joints of external frames of multi-storey buildings designed to the current NZ loading code. Hinge formation occurred in the beams and stable hysteretic behaviour was obtained up to model displacement ductilities of 6 (worst unit) to 18 (best unit). Corresponding prototype building ductilities are shown to be slightly higher. Tests results indicated the importance of matching the yield moment strengths in the haunch with the combined seismic and gravity load distribution.
