The main building of Yokufu-en has been designated “Selected Historical Buildings of Tokyo Metropolitan Government” built after the Great Kanto Earthquake in the Taisho period. This building was designed by Yoshikazu Uchida, a famous university professor and his assistant. As a result of the study, the building has enough strength of structure, and the concrete shows sufficient compressive strength. However, as the 3rd story with having high eccentric factor is necessary to be reinforced for earthquake resistance, the reinforcement plan was designed for obtaining a prescribed seismic capacity performance.
