VERTICAL DYNAMIC PROPERTIES OF SUPER HIGH-RISE RESIDENTIAL BUILDINGS BASED ON RECORDED MOTIONS AND DYNAMIC SOIL-STRUCTURE-INTERACTION EFFECTS

Although Horizontal and rotational dynamic characteristics of super high-rise residential buildings has been studied based on recorded motions during the 2011 Tohoku earthquake, vertical dynamic properties were not fully investigated, which must be strongly affected by the dynamic soil-structure interaction. This study investigates vertical responses of the nine super high-rise residential buildings located in Kanto area using recorded motions including the 2011 Tohoku earthquake. Transfer functions of top responses to ground surface are varied due to vertical soil-structure-interaction with strong dependency of dynamic impedance function.
