Seismic test on 12-story T-shaped coupled shear wall has been conducted under the U.S.- Japan cooperative structural research project on composite and hybrid structures. Objectives of this test are to investigate restoring force characteristics of coupled shear wall, and carrying shear force ratio of tension and compression side walls. In this test, load-transducers were inserted at center of coupling beams to measure axial and shear forces of them. Main results from this test are followings; (1) shear force and varied axial force of each wall are measured, (2) maximum shear force of this system is dominated by the deflection capacity of coupling beams, and its structural drift is 1/67 radian(deflection at the 12th floor / 12-story height), (3) the ultimate deformation capacity of the wall in this system is confirmed up to the structural drift of 1/25 radian.
