Recently, high-rise base-isolated buildings have been increasingly adopted, and the assessment of the habitability of high-rise base-isolated buildings has become an important issue. To investigate issues in habitability assessment, with a one-year return period velocity was estimated, and habitability was assessed based on long-term observation records from the J2-3 Building. The results show that because translational and torsional components have the same phase in several cycles, the habitability assessments from recorded data containing both translational and torsional components are larger than that of separated. Furthermore, the observation data indicates that the influence of higher-order mode components is also significant.
