In this paper, by using the available data on interior beam-column subassemblages tested by the authors, the estimation method of story deformation angles at beam-yielding and maximum-load, and ultimate story-drift has been proposed. And the estimated values are compared with the measured values. The following statements can be made from this study:
(1) The story deformation angles at beam-yielding and at maximum-load are estimated approximately by the addition of deformation in beams, columns and joint panel of subassemblages. These deformations in structural members of subassemblages are estimated by the equations previously developed by the authors.
(2) The ultimate story deformation angles are estimated approximately by the estimation equation proposed in this study, considering the shear stress level in the joint panel and the amount of transverse reinforcement of joint.
