Slip-critical joint, from structural engineering, is a type of bolted structural steel connection which relies on friction between the two connected elements rather than bolt shear or bolt bearing to join two structural elements.
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 ...
A steel detailer is a person who produces detailed drawings for steel fabricators and steel erectors. The detailer prepares detailed plans, drawings and other documents for the manufacture and erection of steel members (columns, beams, braces, trusses, stairs, handrails, joists, metal decking, etc.) used in the construction of buildings, bridges, industrial plans, and nonbuilding structures.
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.
2001—World Trade Center collapse (New York, New York): In the 10 months after the September 11 attacks, crews removed more than 1.6 million tons of debris. Thornton Tomasetti staff were the first engineers on the site on September 11, [ citation needed ] and started work that afternoon. [ 3 ]

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 .
