In the core wall system in high-rise buildings, the four L-shaped core walls at the center effectively reduce seismic vibration. On the other hand, precast core walls are effective for construction because they can be built more quickly than cast-in-place core walls. In this study, a lateral loading test was conducted on a wall column simulating the corner and the area near the corner of an L-shaped core wall under the action of low axial load. The wall column was divided into precast columns, and horizontal tied rebars were concentrated at the second and third floor levels, and the mid height level of the first story. Based on the results of lateral loading tests, the structural performance of the wall column under the action of low axial loadwas clarified.
