Tube (structure)

In structural engineering, the tube is a system where a building is designed to act like a hollow cylinder to give it more support. This system was created by Fazlur Khan while at the architectural firm Skidmore, Owings & Merrill (SOM), in their Chicago office.^[1]

The first example of the tube’s use is the Plaza on DeWitt, in Chicago, Illinois.^[2]
