Abstract:
These recommendations represent a substantial revision of earlier recommendations from this committee. Recommendations are given for member proportions and reinforcement details required for satisfactory confinement of the column core in the joint region, adequate joint shear strength, the proper ratio of columnmoment strength versus beam-moment strength at the joint, and development of reinforcing bars either terminating in or passing through the joint. Commentary is provided to amplify the recommendations and identify available reference material. The recommendations are based on laboratory testing as well as field studies and provide a state-of-the art summary of current infor-mation. Areas needing research are identified. Design examples are presented to illustrate the use of the design recommendations.
