This report is on an earthquake-resistant refurbishment design and construction case for a high-rise SRC rental residential building having v-shaped plane designed by the old seismic code. In this retrofitting design, the building was divided into two, making them well-formed buildings, and retrofitted by k type steel brace. The construction procedure for dividing the residential building into two and the results of monitoring during the construction process were shown in this report. Although the relative displacement and inclination angle increased by the dividing, the deformation angle was about 1/5700 and it was considered that there was no structural problem.
