Abstract

The design and construction of a long-span, seismic isolated office building located in Tokyo and completed in October 2003, meets the needs of a sustainable urban environment. The 6-story building is 20 m × 80 m and uses a large-scale “trussed cage” structure, the upper part of which is supported on six base isolators on independent columns, creating an expansive area at ground level. The building’s seismic design uses artificial earthquake input movement taking into account the soft soil of the site and the frequency of Japan’s earthquakes. We detail the structural system and design concept, construction process, and health monitoring in the section that follow.
