東京晴空塔
As a result of studies into the shinbashira structure and its utility in earthquake-resistance it has, once again, come into use in new buildings and structures, including the Tokyo Skytree. A central feature of the Tokyo Skytree tower is an innovative system to control swaying used here for the first time; it has been dubbed a "shinbashira" after the central pillar found in traditional five-story pagodas. The 375-meter-long, steel-reinforced concrete shinbashira is not directly connected to the tower itself and is designed to cancel out the swaying of the needle-like tower during an earthquake. According to an official with Nikken Sekkei, which designed the structure, the concept was developed on the basis that pagodas rarely topple during earthquakes.
