We performed the response analysis using simulated ground motion records for the scenario earthquakes and/or observed ground motions records. Analysis models are practical models for the high-rise buildings. The cumulative damage of each building is evaluated from the result of the analyses. Our conclusions are; 1) the characteristics of input motions and building responses can be adequately categorized by using a concept of impulse index corresponding to the ratio of the maximum instantaneous input energy to total input energy. 2) the cumulative residual drift and plastic displacement during the in-service period is not so large, whereas the maximum shear story drift angle may equal or larger than 0.02.
