RECONNAISSANCE OF BASE-ISOLATED BUILDINGS AFTER THE 2024 NOTO PENINSULA EARTHQUAKE

To promote the adoption of seismic isolated buildings, validating their seismic safety is important. By using results of scratch recorded equipment installed in the seismic isolated floor, seismic behavior and response of the buildings have been analyzed by previous studies. This paper presents the findings of investigations on the damaged condition of 24 seismic isolated buildings located in Ishikawa, Toyama, and Niigata prefectures after the Noto Peninsula Earthquake of January 1, 2024. The maximum displacement response obtained from the scratch records and that of analytical model are compared and discussed.
