Abstract We observed wind and acceleration of the actual building with seismic isolation structure, and the observed response showed nonlinear behavior. In order to identify an equivalent linear structural model for the maximum response acceleration, the identification method must be devised. Response analysis was performed by spectral modal analysis, which is often used to study wind response. The maximum response acceleration corresponded well with the observed value, but the standard deviation deviated, so the equivalent linear model should be applied limitedly depending on the purpose. A slight difference in the relationship between wind speed and response acceleration has a great influence on the evaluation of habitability. On the other hand, even if the mode of the seismic isolation layer changes, the evaluation is not greatly affected. A parameter study of attenuation constant and mass was performed, and the range of change in evaluation value due to structural model errors was shown.
