AbstractThis paper proposes a vertical distribution of seismic design load of seismically isolated buildings corresponding to diversity of seismic isolation devices such as hysteretic dampers and/or velocity‐dependent dampers. This proposed method is obtained from the relationship between response amplification caused by higher‐mode responses and key parameters such as Isolation ratio and Non‐linearity factor which evaluate structural characteristics of seismically isolated buildings. This response amplification is explained by nonlinear modal analysis with free‐free vibration mode. In addition, it is confirmed that this proposed method adapts to various model of seismically isolated buildings.
