A diagrid (a portmanteau of diagonal grid) is a framework of diagonally intersecting metal, concrete, or wooden beams that is used in the construction of buildings and roofs.[1] It requires less structural steel than a conventional steel frame. Hearst Tower in New York City, designed by Norman Foster, uses 21 percent less steel than a standard design.[2] The diagrid obviates the need for columns and can be used to make large column-free expanses of roofing.[3] Another iconic building designed by Foster, 30 St Mary Axe, in London, UK, known as "The Gherkin", also uses the diagrid system.
British architect Ian Ritchie wrote in 2012:
The origin of 'diagonal' structures is surely the Russian genius Vladimir Shukhov. He pioneered new analytical methods in many different fields, and I have been fortunate to visit some of his constructed projects more than once. Shukhov left a lasting legacy to early Soviet Russia constructivism, and as the leading engineer and mathematician during the late 19th and early 20th century he created hyperboloid, thin shell and tensile structures of extraordinary refinement and elegance.[4]
