Definition of diagrid in English:



  • A supporting framework in a building formed with diagonally intersecting ribs of metal or concrete.

    • ‘At intervals, the double-height spaces are penetrated by the diagrid structure, bleached white like dinosaur ribs.’
    • ‘Within the principal diagrid established by the 36 steel columns that spiral around building (which form an independent self-bracing structure), each floor level is broken down into 72 five-degree modules.’
    • ‘Ends of the shell are stiffened with laminated timber arches braced by a diagrid of tension cables from which hang enclosing cardboard honeycomb panels.’
    • ‘The building's height was made feasible by the use of a peripheral ‘diagrid,’ in which all the steel elements subtly interlock.’
    • ‘Because of the inherent stiffness of the external diagrid, the central core is required to act only as a load-bearing element and is free from diagonal bracing, producing more flexible floor plates.’


1940s: from diagonal + grid.
