单词	diagrid
释义	diagrid /ˈdʌɪəɡrɪd / noun British A supporting framework in a building formed with diagonally intersecting ribs of metal or concrete.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.... 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. Ends of the shell are stiffened with laminated timber arches braced by a diagrid of tension cables from which hang enclosing cardboard honeycomb panels. Origin 1940s: from diagonal + grid.
