Seismic Performance of Interior Reinforced Concrete Beam–Column Joint with Corroded Reinforcement

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.

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.

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.
