"[93] Minister of the Interior Matteo Salvini also blamed supposed EU spending limits for infrastructure, but this was immediately dismissed and disproven by European Commission officials. [21] In 1979/1980, Morandi's similar[22] bridge in Venezuela suffered one or more stay cable failures with collapse imminent. [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. Deputy Prime Minister Luigi Di Maio claimed that they were "definitely to blame.

[71], It was later decided that the bridge would not be repaired but demolished. [17] On pillar 9 they could identify only four global modes, and the deformations of two of these identified modes were not fully compliant. L’Ingegner Riccardo Morandi è stato a più riprese docente universitario. It connected Genoa's Sampierdarena and Cornigliano districts across the Polcevera valley. Other than pre-stress, changes in geometry, such as corrosion in the tendons could impact the resonant frequency. Ingegneria.

[41][43], By the mid-2000s, the A10 route through Genoa and over the bridge had become highly congested. [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. [30] Traditionally, bridges were designed only for a 50-year life span;[23] the bridge failed just under 51 years after its opening. [17] From 1990 onward, the easternmost pillar 11 had its stays strengthened by flanking them with external steel cables. 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).

Precipitati 30 auto e 3 tir: si cercano dispersi. [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.

The bridge is widely called "Ponte Morandi" after its structural designer, the noted engineer Riccardo Morandi.[2]. It also provided a critical artery of European route E80, linking Italy and France. [78], The day after the collapse, Prime Minister Giuseppe Conte declared a state of emergency for the Liguria region, which would last for a year. [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. We all know how bad our infrastructure is in Italy. The Ponte Morandi was a cable-stayed bridge characterised by a prestressed concrete structure for the piers, pylons and deck,[6] very few stays, as few as two per span, and a hybrid system for the stays constructed from steel cables with prestressed concrete shells poured on.

In contrast, with bare tendons which are relatively under-constrained like the strings in a piano, the effect of pre-stress is dominant in determining the resonant frequency. Era stato inaugurato 51 anni fa", "IL PONTE MORANDI ERA DEFINITO UN 'VIADOTTO MALATO' E SEMPRE SOGGETTO A LAVORI DI MANUTENZIONE", "Ing. [75][76], The area under the remaining part of the bridge, including several homes, was evacuated.

The disaster resulted in a drop in the stock price of the road's operator, Atlantia, by 5% the same day and by 25% two days later. [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. [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. As little as a 2% shift could represent severe damage. Ponte Morandi, l’inaugurazione prevista entro primavera 2020 Le prossime tappe del Ponte Morandi: il 1° ottobre sarà varata la prima campata da 50 metri, entro aprile del 2020 è previsto il taglio del nastro.

[65] There is speculation that lightning may have struck the stays, or a landslide could have destabilised the base.

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. The 37-year-old driver at the time of the accident recounted to the media how he looked in shock as the bridge busy with dense traffic collapsed in front of him, as he brought his vehicle to a stop and ran back until he reached firm ground.

Nei confronti degli altri, finora non iscritti nel registro degli indagati, si legge nella nota della Procura, sono emersi indizi di responsabilità. 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. The Ponte Morandi was a cable-stayed bridge characterised by a prestressed concrete structure for the piers, pylons and deck, very few stays, as few as two per span, and a hybrid system for the stays constructed from steel cables with prestressed concrete shells poured on. [51], The initial hypotheses were that a structural weakness or a landslide caused the collapse. Dopo la strage, lo strazio: "Quando ero ministro...

[39][40] The pre-stress in the Ponte Morandi was characterised as relatively small from the start. [41] Gentile had performed similar modal analyses on pillar 11 in the 1990s. As part of the initial study and report, the Autostrade company measured that the bridge carried 25.5 million transits a year, with traffic having quadrupled in the previous 30 years and "destined to grow, even in the absence of intervention, by a further 30% in the next 30 years". The work on the reinforcement of the stays on pillars 9 and 10 would have needed to be finished within five years. [18][19] Pillar 10 had the stays at the top strengthened with steel sheathing in the 1990s. [44] The study showed that, in the option for improving what was termed as the "low gutter", it would be more economical to replace the bridge with a new one north of its current location, and then to demolish the existing bridge. In Genoa, in 2017, a confidential university report noted disparities in the behaviour of the stays of the now collapsed pillar 9. Camomilla: come e perché intervenimmo senza demolirlo sugli stralli della pila 11 del Ponte Morandi nel 1992", "Ponte Morandi, ispezioni su stralli erano fallite: Ministero ha approvato un progetto incompleto", "Ignored university reports about Morandi bridge: "Deformed pylons and oxidized cables, "Ponte Morandi a Genova, una tragedia annunciata? [82], The Italian transport minister Danilo Toninelli, in office for the first time since 1 June 2018, described the incident as "an immense tragedy",[47] but he was also known to be member of the Five Star Movement, the political party which in 2012 said that the risk of a collapse of Morandi Bridge was just a silly fairy tale, because "the bridge would have lasted another hundred years", quoting a 2009 evaluation by Autostrade.
