Abstract This paper explains about structural planning and structural design of the high-
rise building in Toranomon-Azabudai Project (A Block) which is now under construction.
The building is about 330 meters high, has 4.2 aspect ratio, and the outline of the building
has shallow curve. We adopted seismic response control structure. The building is a steel
rigid frame structure with braces, and it has enough stiffness to obtain its primary natural
period to be less than about seven seconds, in consideration of wind response, seismic
response and inhabitability for the wind shaking. In terms of business continuity plan, the
building has a high seismic performance; value of story drift angle shall be 1/150 or less and
members of the building remain almost undamaged while or after a large earthquake. Active
mass dumper shall be installed at the top of the building to improve inhabitability while
strong wind is blowing.
