Khan's central innovation in skyscraper design and construction was the idea of the "tube" structural system for tall buildings, including the framed tube, trussed tube, and bundled tube variants. His "tube concept", using all the exterior wall perimeter structure of a building to simulate a thin-walled tube, revolutionized tall building design ...
May 5, 2017 · This innovative “tube” system was first employed in Chicago’s 43-story Dewitt-Chestnut apartment building (1963-1966), with its rigid screen of closely spaced exterior columns and open floorplates. But it was the 100-level John Hancock Center (1965-1969) that showed the world that the future of skyscraper design was tubular.
Feb 9, 2016 · The Framed Tube. In developing the lateral resisting system for the 43-story tall Chestnut-DeWitt Apartments in Chicago, Khan saw an opportunity to step back from traditional lateral design...

When one looks at a text on tall building design today, one finds these recognizable structure types: the framed tube, the shear wall frame interaction, the trussed tube, the bundled tube, and the composite system (also developed by Fazlur Khan).
Fazlur Rahman Khan, a structural engineer from Bangladesh (then called East Pakistan) who worked at Skidmore, Owings & Merrill, defined the framed tube structure as "a three dimensional space structure composed of three, four, or possibly more frames, braced frames, or shear walls, joined at or near their edges to form a vertical tube-like ...

Bundle tube. One of Khan's most important variations of the tube structure concept was the "bundled tube," which he used for the Sears Tower and One Magnificent Mile. The bundle tube design was not only the most efficient in economic terms, but it was also "innovative in its potential for versatile formulation of architectural space.
