Cyclic Loading Tests

Cyclic loading tests simulating the effects of a severe earthquake were conducted on an interior reinforced concrete beam-column joint. The unit had been designed according to
the requirements of the draft (1980) SANZ concrete design code except that the horizontal shear reinforcement in the joint core was deliberately made only 78% of that required by the draft SANZ code. The joint core hoops commenced to yield in the first loading run up to the beam flexural strength and with subsequent loading runs degradation of stiffness and strength occurred due to damage concentrating in the joint core. It
was evident that the draft SANZ code is not conservative in its approach to the design of shear reinforcement for interior reinforced concrete beam-column joints.

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.

Four beam-interior column Units were designed, constructed and tested subjected to simulated earthquake and gravity loading. One Unit followed the requirements of the New Zealand concrete design code NZS 3101:1982 for structures designed for ductility. The other three Units only partly followed the requirements of NZS 3101, in order to obtain information on the behaviour of beam-column joints of limited ductility. Plastic hinging was designed to occur in the beams. The major test variables were the quantity of horizontal and vertical shear reinforcement in the beam-interior column joint cores and the diameter of the beam longitudinal reinforcing bars passing through the joint cores. The test results indicted that the current NZS 3101 detailing requirements for shear and bond in the beam-interior column joint core regions of ductile reinforced concrete frames could be relaxed.

Reinforced Concrete Frame Structures

The characteristics of the shear deformation inside the beam-column joint core of reinforced concrete frame structures subjected to seismic loading are discussed in this paper. The paper presents the formulation of an analytical model based on experimental observations. The model is intended to predict the expansions of beam-column joint core in the horizontal and vertical directions. The model describes the strain compatibility inside the joint in an average sense. Its predictions are verified utilizing experimental measurements obtained from tests conducted on beam-column connections. The model is found to adequately predict the components of shear deformation in the joint core and satisfactorily estimates the average strains in the joint hoops up to bond failure. The model may be considered as a simple, yet, important step towards analytical understanding of the sophisticated shear mechanism inside the joint and may be implemented in a controlled-deformation design technique of the joint.
