EARTHQUAKE RESPONSE ANALYSIS OF SUPER HIGH-RISE RESIDENTIAL BUILDING UNDER THE CONDITION OF MISSING RECORDS AT 1ST FLOOR DURING THE 2011 OFF THE PACIFIC COAST OF TOHOKU EARTHQUAKE

Abstract

This study investigates the dynamic responses of a super high-rise residential building during the 2011 off the Pacific coast of Tohoku earthquake and its pre- and after-shocks based on temporally consecutive nonlinear response analyses. The missing input motion records during the main-shock are compensated from the soil-pile-foundation interaction analysis and records at the tip of piles. The earthquake response simulation is compatible well with records in the building. Distribution of the maximum story drift angle is also discussed in related with the actual indoor damages.
