Experimental studies of four sandwich walls with the same height but different height-width ratio and different vertical compressive stress, which were subjected to in-plane cyclic loading, were presented and tests results were discussed. Based on actual mechanical characteristics, the vertical and horizontal loads were loaded on the center of the interior walls. The whole process of loading-deforming-damaging-cracking-yielding-failure was observed during the test. The failure characteristics, hysteretic curves, skeleton curves, displacement ductility, bearing capacity, behavior of the tie bar and coordination between two cavity walls were analyzed. The result showed that the interior walls and the outer walls worked together well, and the outer walls were slightly damaged; shear slipping and pinching occurred in the test; shear failure occurred when the ratio of height to width was small and bending-shear failure occurred when the ratio increased and the ultimate bearing capacity of the walls increased with the increase of the axial compressive ratio. The shear capacity of the walls in the test is greater compared with the GB 50003-2001 Code.
