During the 2011 off the Pacific Coast of Tohoku earthquake, most super high-rise RC buildings constructed in the metropolitan area had suffered severe shaking, leading to variation of dynamic properties due to structural damages. This study describes the damage estimation of the super high-rise RC building during the main shock using the 3D frame model. Their varying dynamic characteristics are discussed based on the system identification method. The dynamic properties during aftershocks are also investigated in view of the residual seismic performance after experiencing moderate-level structural damages.
