RC BEAM-COLUMN JOINTS UNDER LARGE LOAD REVERSALS

An experimental investigation to determine the shear strength of reinforced concrete beam-column joints is presented. The test specimens consisted of six exterior beam-column subassemblages. The primary variable were the amount of transverse reinforcement in the joint, the magnitude of axial load on the column, and the severity of the load reversals applied to the beam. The experimental results indicate that the shear resisted by the concrete in the joint was considerably greater than the values suggested by current recommendations. The increase in shear strength is assumed to be influenced by the ratio of the sum of column flexural capacities to that of the beams framing into the joint. It is concluded that this ratio should be considered when designing a beam-column joint. /Author/
