The Response of reinforced concrete wall-frame structures subjected to earthquake motion was investigated by testing a full-scale six-story specimen on the world's largest tri-axial shaking table "E-Defense". The test specimen consisted of three parallel three-bay frames in the longitudinal direction. The central frame had a multi-story structural wall in the center bay continuous from the 1st to the 6th story. To be able to monitor shear force carried by the structural wall at the 1st story, 3-component force transducers were instrumented between foundation beams and the shaking table. The test specimen was subjected to a series of strong earthquake motions and finally nearly collapsed caused by shear failure of short columns and shear slipping failure of the structural wall at the 1st story. This paper outlines measurement plan of 3-component force transducers and also examines the shaking table test results for rigidity at the bottom of the wall, restoring force characteristics of the structure, and measured shear force carried by the 1st-story structural wall.
