Diagrid (a portmanteau of diagonal grid) is a design for constructing large buildings with steel that creates triangular structures with diagonal support beams.[1] It requires less structural steel than a conventional steel frame. Hearst Tower in New York City, designed by Sir Norman Foster, reportedly uses 21 percent less steel than a standard design. The Diagrid also obviates the need for large corner columns and provides a better distribution of load in the case of a compromised building. Another building designed by Sir Norman Foster, 30 St Mary Axe, known as "the Gherkin", also makes use of this structural 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. ..."
