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. ..." [2]

Diagrid vs. Other Structural System
The diagrid system has a lot of benefits that can make it more favored be the designer against other systems. Some of
Mostly column free exterior and interior
Generous amounts of day lighting due to dearth of interior columns and structure
Roughly 1/5th reduction in steel possible
Simple construction techniques (although they need to be perfected yet)
Full exploitation of the structural material
Similar design/construction tolerances as a typical moment frame construct (for instance: a type. columnar ele
allown for compression in the final product in a M.F. project. The same can be said for a DiaGrid project.)
Free and clear, unique floor plans are possible
Aesthetically dominate and expressive
