L’ingegnere Riccardo Morandi, progettista del ponte crollato a Genova, era considerato uno dei massimi esperti nel settore. The bridge was designed by Riccardo Morandi. Forbindelsen blev officielt åbnet den 4. september 1967, og broen blev navngivet efter designeren Riccardo Morandi. Scientists from NASA's Jet Propulsion Laboratory in Pasadena, California, developed a method of analyzing satellite data to detect millimeter-size changes. The bridge was an engineering and architectural landmark since its construction. Ingegneria. [9][10][11], The viaduct was built between 1963 and 1967 by the Società Italiana per Condotte d'Acqua, costing 3.8 billion Italian lire and opened on 4 September 1967. Ponte Morandi (Morandi-broen) var en del af Polcevera-viadukten (italiensk: Viadotto Polcevera) på motorvej A10 i Italien.Den krydsede floden Polcevera mellem distrikterne Sampierdarena og Cornigliano i Genova, Liguria. [47][48] The collapsed span was centred on the westernmost cable-stayed pillar, pillar 9,[47] and crossed the Polcevera river as well as an industrial area of Sampierdarena. Other parts landed on the tracks of the Turin–Genoa and Milan–Genoa railways, and on warehouses belonging to Ansaldo Energia, an Italian power engineering company. Era stato inaugurato 51 anni fa", "IL PONTE MORANDI ERA DEFINITO UN 'VIADOTTO MALATO' E SEMPRE SOGGETTO A LAVORI DI MANUTENZIONE", "Ing. The Ponte Morandi bridge, named after its designer Riccardo Morandi, is part of the Polcevera viaduct and was a … [34][35], Workers were installing new heavy concrete Jersey barriers on the Ponte Morandi before it collapsed, reducing the already low compressive pre-stress on the concrete of the stays and increasing the loads. It featured diagonal cable-stays, with the vertical trestle-like supports made up of sets of Vs: one set carrying the roadway deck, while the other pair of inverted Vs supported the top ends of two pairs of diagonal stay cables. La costruzione del Ponte Morandi girato in 8mm. [87] Some of the victims' families refused to attend the service and instead hosted private funerals.

[50] The latter were largely empty because the collapse occurred on the eve of the Italian public holiday, Ferragosto. [12], The bridge had been subject to continual restoration work from the 1970s on due to an incorrect initial assessment of the effects of creep of the concrete. [77], The railways connecting Genoa Sampierdarena (and Genoa Piazza Principe) with Genoa Borzoli and Genoa Rivarolo were closed immediately as a result of the bridge's collapse. [59][60][61] A preliminary investigative report suggested the pillar itself may have collapsed first,[62][63][64] but Genoa prosecutors had not provided the report's authors with a local video showing the southern stays gave way first.

[89], The collapse raised concerns about the general condition of infrastructure in Europe, with studies in Italy, France, and Germany suggesting that a significant number of bridges are in need of renovation or replacement due to corrosion and structural deterioration. "[87], The ruling coalition put pressure on the managers of the road, Autostrade per l'Italia (which is part of the Atlantia group).

[68], At the time of the collapse, the bridge was managed by Atlantia S.p.A. (formerly Autostrade S.p.A.), a holding company operating toll motorways and airports, which is controlled by the Benetton family. La Procura di Genova ha reso pubblica la lista aggiornata degli indagati per il crollo del ponte Morandi, del 14 agosto scorso. Riccardo Morandi, oltre a concepire grandi opere infrastrutturali, nel corso della sua carriera fu dedito ad approfondire lo studio del calcestruzzo armato precompresso. Ha tenuto corsi di forma e strutture di ponti presso la facoltà di Architettura dell’Università di Firenze. In Liguria da ore piove abbondantemente, la Protezione civile ha dichiarato l’allerta arancione e una parte del chilometro del ponte Morandi era sottoposto anche ad un intervento di sistemazione, a provarlo è una gru, dicono, presente da qualche giorno. Lo stato precedente della struttura dicono fosse pietoso. [75][76], The area under the remaining part of the bridge, including several homes, was evacuated. [41][43], By the mid-2000s, the A10 route through Genoa and over the bridge had become highly congested. However, Autostrade, the company that maintained the bridge, objected that the video still does not show all bridge structures and so it does not really explain the cause. [50] Davide Capello, the former goalkeeper for Cagliari, survived without injury and was able to walk away from his car, even though it dropped 30 metres (100 ft) before becoming wedged between parts of the fallen bridge. 9 started dropping virtually simultaneously. Precipitati 30 auto e 3 tir: si cercano dispersi. [94] The position of the Benetton family, whose company owns 30% of Atlantia, has also come under scrutiny. Pylon 9 did not receive this upgrade", "Genova, crollo del ponte autostradale, nel mirino i cavi di cemento armato. [10] About 30% of the tendons had corroded away. [31][54][55][56][57][58] With only four stays, one of them giving way might have been enough for the structure to lose stability. Ad alcuni, già noti, vengono addebitate nuove ipotesi di reato. Dal 1971 è stato Research Professor presso l’Università Statale della Florida. L’Ingegner Riccardo Morandi è stato a più riprese docente universitario. However, these two committee members were immediately criticised for being among the signatories of the February 2018 government report that failed to impose precautionary measures on the weakened bridge. [30] Traditionally, bridges were designed only for a 50-year life span;[23] the bridge failed just under 51 years after its opening.

The study highlighted how the traffic volume, with daily queues at peak hours joining the Autostrada Serravalle, produced "an intense degradation of the bridge structure subjected to considerable stress", with the need for continuous maintenance. Ponte Morandi (English: Morandi Bridge), officially Viadotto Polcevera (English: Polcevera Viaduct),[1] was a road viaduct in Genoa (Italy), constructed between 1963 and 1967 along Italy's A10 motorway over the river Polcevera, from which it derived its official name. The remains of the original bridge were demolished in August 2019. Their analysis suggests that the deck between pier 10 and pier 11 had minimal movements until early 2015, and that between March 2017 and August 2018 there was a significant increase in structural changes (noting that the collapsed pier is pier 9, without any consequential damage to piers 10 and 11, and the between deck). It originated from the nearby Ferrometal company cameras, showing that both southern stays and locally attached road sections at pillar no. [31][38] In pre-stressed concrete beams, such a difference could represent the entire effect of the non-linear pre-stresses. [45][failed verification], On 14 August 2018 at around 11:36 local time (09:36 UTC), during a torrential rainstorm, a 210-metre (690 ft) section of Ponte Morandi collapsed.

[51], The initial hypotheses were that a structural weakness or a landslide caused the collapse. According to the Corriere della Sera, this was the 11th bridge collapse in Italy since 2013. [80], The Italian Football Federation announced that a minute of silence would be held for the victims of the collapse before all football events across the country during the weekend that followed the incident. ⭕️ ROME 25/12/1989, deceased on Christmas day, aged 87, the engineer and architect Riccardo Morandi.
