| Popis: | The paper describes the testing of two reinforced concrete beam-column joint units tested under incremented-static cyclic loading. The full size test units were based upon an interior beam-column joint of a four-storey framed building designed to the current NZ loading code and represent refinements on two previously tested conventional joints of similar dimensions. One unit differed from common practice by having a post-tensioned beam stressed to balance the floor dead load of the prototype structure whilst the second unit was detailed with haunched beams. Hinge formation occurred in the beams and stable hysteretic behaviour was obtained up to displacement ductilities of 10 for the prestressed unit and 6 for the haunched unit. The test results are analysed in terms of the draft NZ design code, DZ 3101, and the ACI Recommendations for beam-column joint design. |
