A seismic performance of full-scale precast reinforced concrete beam-column corner joint with corbel was examined in the laboratory. The precast beam-column joint designed using BS8110:1:1997 was tested under lateral cyclic loading up to +1.5% drift. Displacement ductility of precast beam-column joint with corbel was determined. The visual observation showed that the damage occurred at the corbel of beam-column joint. Major cracks were also observed at the cast-in-place area above the joint area. In this paper, the damage state of the specimen is categorized in accordance to HAZUS®99 and the vulnerability of the specimen was assessed using fragility curve.

The design, construction and testing of two large reinforced concrete beam-column assemblies, representing an interior and an exterior joint, are described. Member details were based on an actual frame building designed by the M.W.D. Extensive results are presented which indicate very satisfactory behaviour particularly in the joint region. Hinges formed in the beams in all cases, and stable behaviour was obtained at displacement ductility factors of up to 6 and 8 for the interior and exterior test units respectively. Results are assessed in terms of design assumptions, and tentative design recommendations are made.

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.

The experimental work on two full-scale precast concrete beam-column corner joints with corbels was carried out and their seismic performance was examined. The first specimen was constructed without steel fiber, while second specimen was constructed by mixed up steel fiber with concrete and placed it at the corbels area. The specimen were tested under reversible lateral cyclic loading up to ±1.5% drift. The experimental results showed that for the first specimen, the cracks start to occur at +0.5% drifts with spalling of concrete and major cracks were observed at corbel while for the second specimen, the initial cracks were observed at +0.75% with no damage at corbel. In this study, it can be concluded that precast beam-column joint without steel fiber has better ductility and stiffness than precast beam-column joint with steel fiber. However, precast beam-column joint with steel fiber has better energy dissipation and fewer cracks at corbel as compared to precast beam-column joint without steel fiber.
