VIBRATION CHARACTERISTICS OF HIGH-RISE STEEL BUILDING IN SHINJUKU SKYSCRAPER DISTRICT BEFORE AND AFTER THE 2011 OFF THE PACIFIC COAST OF TOHOKU EARTHQUAKE

1) The natural periods in the event of the main shock increased by five to eight percent before the main shock. With the assumption that the reduction of rigidity was caused by the peeling of the nonstructural elements, it is estimated that the non-structural elements contributed to about 10 to 15% of the rigidity in the event of the main shock before the main shock occurred.
