How Upside-Down Models Revolutionized Architecture, Making Possible St. Paul’s Cathedral, Sagrada Família & More

For 142 years now, Sagra­da Família has been develop­ing towards the sky. Or no less than that’s what it sort of feels to be doing, as its ongo­ing con­struc­tion actual­izes ever extra ful­ly a number of bureaucracy that feel and look now not somewhat of this earth. It makes a type of sense to be informed that, in design­ing the cathe­dral that will stay a piece in development close to­ly a cen­tu­ry after his dying, Antoni Gaudí constructed a mod­el upside-down, mak­ing use of grav­i­ty within the oppo­website strategy to which we nor­mal­ly recall to mind it as act­ing on a construct­ing. However as archi­tec­ture YouTu­ber Stew­artwork Hicks explains within the video above, Gaudí was once onerous­ly the primary to make use of that tech­nique.

Take St. Paul’s Cathe­dral, which Christo­pher Wren decid­ed to make the tallest construct­ing in Lon­don in 1685. It includ­ed what will be the top­est dome ever constructed, at 365 toes off the bottom. “For a tra­di­tion­al dome design to achieve this peak, it must span an open­ing that’s 160 toes or 49 meters vast, however this made it a lot too heavy for the partitions under,” says Hicks. “Exist­ing tech­niques for construct­ing this simply may just­n’t paintings.” Input sci­en­tist-engi­neer Robert Hooke, who’d already been fig­ur­ing out techniques to mod­el forces like this via cling­ing chains from the ceil­ing.

“Hooke’s genius was once that he actual­ized that the chain in his exper­i­ments was once cal­cu­lat­ing the according to­fect form for it to stay in ten­sion, since that’s all it may do.” He defined domes as, phys­i­cal­ly, “the precise oppo­website of the chains. His well-known line was once, ‘As hangs the flex­ile line, so however invert­ed will stand the inflexible arch.’ ” In oth­er phrases, “should you turn the form of Hooke’s chain exper­i­ments the wrong way up, the forces turn, and this form is the according to­fect com­pres­sion sys­tem.” Therefore the dis­tinc­tive­ly elon­gat­ed-look­ing form of the dome at the com­plet­ed St. Paul’s Cathe­dral, a depar­ture from all archi­tec­tur­al prece­dent.

The form upon which Wren and Hooke set­tled grew to become out to be very sim­i­lar to what archi­tec­ture now is aware of as a cate­nary curve, a con­cept impor­tant certainly to Gaudí, who was once “well-known­ly enam­ored with what some name organ­ic bureaucracy.” He made detailed mod­els to lead the con­struc­tion of his initiatives, however after the ones he’d left in the back of for Sagra­da Família have been destroyed via anar­chists in 1936, the developers had noth­ing to move on. Most effective in 1979 did the younger archi­tect Mark Bur­ry “imag­ine the mod­els upside-down,” which caused a brand new underneath­stand­ing of the construct­ing’s com­plex, land­scape-like bureaucracy. It was once a sim­i­lar phys­i­cal perception that made pos­si­ble such dra­mat­ic mid-cen­tu­ry construct­ings as Anni­bale Vitel­lozzi and Pier Nervi’s Palazzet­to del­lo Recreation and Eero Saari­nen’s TWA Flight Cen­ter: natural Area Age, however root­ed within the Enlight­en­ment.
