Exterior reinforced concrete (RC) beam-column connection is one of the most crucial zones in a reinforced concrete moment resisting frame. The details of some parameters within this joint can affect to its behavior and greatly influences the strength and ductility of overall frame. In this research, parameter studies of three-dimensional models were studied by finite element ABAQUS software for exterior RC joint subjected to monotonic loading. These studies involving thirty specimens were conducted to investigate the influence of concrete strength, anchorage length, anchorage shape of reinforcement and stirrup occurence within the joint panel. The studied results indicated that the addition of beam or column stirrups within joint panel, the concrete strength and anchorage shape can affect the joint behavior in some specified cases. The influence of anchorage length is not considered when its value is less than the one given in TCVN 5574–2018.
