Seismic test on 12-story T-shaped coupled shear walls have been conducted under the U.S.- Japan cooperative structural research project on composite and hybrid structures. This paper discusses the mechanisms of carrying shear force ratio between tension and compression side walls in coupled shear walls. The factors affecting on the mechanisms of shear force carrying ratio in coupled shear walls are appointed as follows; 1) difference of the wall stiffness in tension and compression side walls, 2) pinching effect of the wall, 3) wedge action of the coupling beams, and 4) residual compressive axial force of the coupling beams. Among these factors, (1) pinching of the wall, wedge action of the coupling beams and residual compressive axial force of the coupling beams are main factors to explain this mechanisms, but (2) difference of the wall stiffness is not a effective factor in this test.
