Parmi les r\u00e9ponses des principaux ing\u00e9nieurs de l'\u00e9poque, le projet du c\u00e9l\u00e8bre artiste et scientifique italien L\u00e9onard de Vinci se distinguait par son originalit\u00e9. Les ponts traditionnels de l'\u00e9poque avaient une forme d'arc bien cintr\u00e9 avec plusieurs trav\u00e9es. Pour le pont au-dessus de la baie, il aurait fallu un minimum de 10 supports, mais L\u00e9onard a imagin\u00e9 un pont de 280 m\u00e8tres de long sans aucun support. Le projet de l'\u00e9rudit italien n'a pas \u00e9t\u00e9 retenu. Nous ne pouvons pas voir cette merveille. Mais ce projet \u00e9tait-il fonctionnel ? Ce sont des ing\u00e9nieurs du MIT qui ont r\u00e9pondu \u00e0 cette question, en s'appuyant sur les esquisses de L\u00e9onard. <noindex><a rel=\"nofollow noopener noreferrer\" href=\"http:\/\/news.mit.edu\/2019\/leonardo-da-vinci-bridge-test-1010\" target=\"_blank\">ils ont construit<\/a><\/noindex> une maquette du pont \u00e0 l'\u00e9chelle 1:500 et l'ont test\u00e9e sous une gamme de charges possibles.<\/p>\n<p><img decoding=\"async\" alt=\"Les ing\u00e9nieurs ont v\u00e9rifi\u00e9 le projet du plus grand pont en arc du monde, Leonardo da Vinci\" src=\"\/wp-content\/uploads\/2019\/10\/11cad0c28f19c0926df61e72943fb76b.png\" style=\"display:block;margin: 0 auto;\" \/><\/p>\n<p>En r\u00e9alit\u00e9, le pont aurait \u00e9t\u00e9 compos\u00e9 de milliers de pierres taill\u00e9es. Il n'y avait pas d'autre mat\u00e9riau appropri\u00e9 \u00e0 l'\u00e9poque (les scientifiques ont tent\u00e9 de se rapprocher le plus possible des technologies de construction de ponts de l'\u00e9poque et des mat\u00e9riaux disponibles). Pour fabriquer la maquette du pont, des sp\u00e9cialistes modernes ont utilis\u00e9 une imprimante 3D et ont divis\u00e9 le mod\u00e8le en 126 blocs de forme pr\u00e9d\u00e9finie. Les pierres ont \u00e9t\u00e9 pos\u00e9es successivement sur des \u00e9chafaudages. Apr\u00e8s la pose de la pierre angulaire au sommet du pont, les \u00e9chafaudages ont \u00e9t\u00e9 retir\u00e9s. Le pont est rest\u00e9 debout et aurait certainement dur\u00e9 des si\u00e8cles. L'\u00e9rudit italien de la Renaissance a tout pris en compte, de l'instabilit\u00e9 sismique de la r\u00e9gion aux charges lat\u00e9rales sur le pont.<\/p>\n<p>La forme d'arc aplati choisie par L\u00e9onard a permis d'assurer la navigation dans la baie m\u00eame pour les voiliers avec des m\u00e2ts relev\u00e9s, et la structure \u00e9vas\u00e9e vers la base garantissait la r\u00e9sistance aux charges lat\u00e9rales et, comme l'ont montr\u00e9 les exp\u00e9riences avec la maquette, la r\u00e9sistance sismique. Les plateformes mobiles \u00e0 la base de l'arc pouvaient se d\u00e9placer sur des distances significatives sans que l'ensemble de la structure ne s'effondre. La gravit\u00e9 et aucun ancrage par le biais de mortiers ou de fixations - L\u00e9onard savait ce qu'il
