Database on the structural characteristics of super high-rise residential buildings are constructed based on documents for the 77 buildings used in the structural design. The masses, linear and nonlinear springs are statistically compiled in terms of normalized height-wise distribution using vibration analysis models for the 39 super high-rise RC buildings. Nonlinear earthquake responses of these buildings are evaluated using several input motions used in the structural design. Equivalent natural periods are found to increase 1.8 times from the initial condition for the level-2 excitation.
