Most of the domestic apartment are reinforced concrete shear wall structures that high stiffness and low ductility, so most of the damping system that apply slit dampers to lintel beams are applied. The slit damper has a damping effect in a single direction, and the energy dissipation capacity due to flexural deformation is somewhat inferior. In this study, In order to complement the existing slit damper, a slit damper combined with a steel cable was proposed, and the seismic performance was analyzed and damping effect was verified through structural performance experiments. As a result of the incremental loading test, the strength, energy dissipation, and equivalent damping ratio of the cable-slit damper specimen increased compared to the steel cable damper specimens. And specimen applied in the shear-direction showed higher damping performance than specimen applied in the roll-direction, but the roll direction also showed similar damping performance to the shear direction. The proposed lintel-type cable-slit damper has increased ductility compared to the cable damper, and the damping performance increased in the out-of-plane direction compared to the conventional lintel-type slit damper according to the roll direction damping effect of the cable damper.
