It was used soon after for the John Hancock Center and in the construction of the World Trade Center. A variation on the tube frame is the bundled tube, which uses several interconnected tube frames. The Willis Tower in Chicago used this design, employing nine tubes of varying height to achieve its distinct appearance. The bundle tube design ...
Shear (and tension) loads can be transferred between two structural elements by either a bearing-type connection or a slip-critical connection. In a slip-critical connection, loads are transferred from one element to another through friction forces developed between the faying surfaces of the connection. These friction forces are generated by ...
The Research Council on Structural Connections (RCSC) is a research organization focused on bolted structural connections. Their technical standard on this subject is cited in the US steel design code. [1] Prior to 1980, the organization was known as the Research Council on Riveted and Bolted Structural Joints (RCRBSJ).

The American Institute of Steel Construction (AISC) is a not-for-profit technical institute and trade association for the use of structural steel in the construction industry of the United States. AISC publishes the Steel Construction Manual, an authoritative volume on steel building structure design that is referenced in all U.S. building codes.
Steel frame structure Rectangular steel frame, or "perimeter frame" of the Willis building (at right) contrasted against the diagrid frame at 30 St Mary Axe (at center), in London. Steel frame is a building technique with a "skeleton frame" of vertical steel columns and horizontal I-beams, constructed in a rectangular grid to support the floors ...
The design and use of steel frames are commonly employed in the design of steel structures. More advanced structures include steel plates and shells . In structural engineering, a structure is a body or combination of pieces of the rigid bodies in space that form a fitness system for supporting loads and resisting moments .
In 1953 and 1954, the original plans for a brick-faced structure were changed to that for a structure with embossed steel panels, even though at the time, steel was more expensive than brick. [ 16 ] [ 37 ] Ruffin and Galbreath had connections to U.S. Steel , which offered to cover the cost difference of steel, and because such a design would ...
