概要	In a reinforced concrete building with core shear walls, the core resists most of the seismic force, so that the damages would be concentrated at the wall base due to the large shear force and bending moment. Diagonal cracks caused by this shear force reduce the shear stiffness of the core wall substantially. As shear stiffness cannot be restored by repair works, it is desirable to minimize such diagonal cracks. This paper examines the behavior of shear walls with de-bonded diagonal reinforcements to reduce the damage and so ensure good repairability. Test results showed that the number of cracks differed greatly even for the same load-carrying capacity. Repair work was easier than with the common parallel reinforced wall. In conclusion, the newly developed earthquake resisting wall reduces damage, shows good performance, and can be reused even after a severe earthquake.
