This paper introduces a design case of 230-meter-tall mid-story-isolation skyscraper in Roppongi, Tokyo. Since the response reduction by seismic isolation on buildings over 200-meter-tall is smaller than general low-rise buildings, these buildings hardly adopted mid-story-isolation structure. Mid-story-isolation buildings are adopted to reduce the response in the upper part of the building, but in actually, the response acceleration is often largest just below the isolation story. In this paper, we introduce the architectural and structural planning for adopting a mid- isolation structure for a skyscraper building and solution methods in this project. The realization of this building presents new possibilities for skyscrapers and mid-story isolation buildings. |
