The redevelopment of Tokyo Central Station is one of the largest and most important projects in the heart of the city. The building complex consists of two buildings, each around 200 m high, the associated entrance buildings and a canopy (a steel membrane roofing).
Wide-Span Membrane Structure with Complex Geometry
The “Yaesu GranRoof” canopy designed by Werner Sobek connects the two high-rise buildings over a length of almost 300 m and at the same time provides weather protection for the new entrance buildings. The long-span membrane structure required extraordinary engineering skills due to its complex geometry and the high, outstanding earthquake loads.
In 2015, the project was awarded the JSCA Incentive Award.
