- Abstract
- Six full-sized interior beam-to-column subassemblages were tested under quasi-static loading which was intended to simulate earthquake input. Three variables were investigated: (1) percentage of transverse hoop reinforcement in the joint; (2) joint shear stress level; and (3) presence of transverse beams and slab on half of the specimens. It was concluded that the joint shear stress level was critical for the satisfactory performance of beam-to-column connections without transverse beams and slab. A joint performance index is proposed which integrates the effect of pertinent variables influencing the joint behavior. A hysteretic model for beam-to-column subassemblages is developed from the hysteretic behavior of the specimens tested.
