STUDY ON REAL INDOOR DAMAGES OF SUPER-HIGH-RISE RESIDENTIAL BUILDINGS DURING THE 2011 OFF THE PACIFIC COAST OF TOHOKU EARTHQUAKE RELATED WITH STRUCTURAL RESPONSES

Abstract

To grasp indoor damages of super high-rise residential buildings during the Pacific coast of Tohoku earthquake, the height distributions of real damages to interior materials and nonstructural components were investigated based on the repair lists and questionnaire survey. Then the indoor damages were compared with the interstory drift angle of the buildings assessed by the simple presumption method based on the strong motion data recorded at the buildings during the main shock. Consequently, the number of damages at the lower stories were greater than the higher stories. Then the damages tend to be greater with increasing the interstory drift angle.
