Structural design of Tokyo Skytree

Abstract

This paper describes the structural design of TOKYO SKYTREE® which was completed in May last year. This tower is the world's highest freestanding steel tower, and it was planned to be the central facility for digital broadcasts in the Tokyo area. Structures in Japan are required to be sufficiently safe against the severe natural environment of Japan, which include not only earthquakes but also typhoons. This tower is also to serve the important role of distributing information during disasters, so even more severe criteria were provided for its design. The following is an introduction to the structural design of TOKYO SKYTREE, which satisfies the strict design conditions using a unique The Core Column System, vibration control system.
