摘要

This paper presents four full-scale testing on lightly reinforced interior beam-column joints under reversed cyclic loading. The main characteristic of the specimens is that no transverse reinforcement was provided in the joint panel and the beam reinforcement had large diameter resulting in relatively poor bond condition. All the specimens failed in joint panel with gradual strength deterioration, severe stiffness and bond degradation. Anchorage of the beam reinforcement passing through the joint panel played a prominent role on the column shear strength, while column axial load had relatively stronger effect on the deformational behavior of the beam-column sub-assemblage.
