For the plaster finished ceiling in the historic building, aseismic renewal method was developed. The method consists of the earthquake resistance by fixation of the ceiling base and the dropping prevention using mesh sheet and steel wire. Through experiments and numerical analysis, it was verified that the developed aseismic reinforcement method has acquired earthquake resistance performance. Utilizing measurement technology and BIM, we carried out construction with high precision in a short construction period. With this developed aseismic method, we were able to improve the earthquake resistance and fall prevention of the ceiling without changing the existing construction method, materials and appearance.
