[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. [92] A resident of Genoa told reporters: "The central government will scapegoat the bridge company, the company will scapegoat someone else — they're all to blame. Era stato inaugurato 51 anni fa", "IL PONTE MORANDI ERA DEFINITO UN 'VIADOTTO MALATO' E SEMPRE SOGGETTO A LAVORI DI MANUTENZIONE", "Ing. [21] In 1979/1980, Morandi's similar[22] bridge in Venezuela suffered one or more stay cable failures with collapse imminent. ⭕️ ROME 25/12/1989, deceased on Christmas day, aged 87, the engineer and architect Riccardo Morandi. 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). La costruzione del Ponte Morandi girato in 8mm. The effects would be reduced by the composite nature of the stays when observing global modes. [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. Eyewitnesses reported that the bridge was hit by lightning before it collapsed. [73], Construction began on the replacement Genoa-Saint George Bridge, designed by the Italian Genoese born architect Renzo Piano, on 25 June 2019, and it was completed in the spring of 2020. [17] On pillar 9 they could identify only four global modes, and the deformations of two of these identified modes were not fully compliant.

[14], In a 1979 report, Morandi himself recommended for authorities to "remove all traces of rust on the exposure of the reinforcements, fill the patches with epoxy resin, and cover everything up with elastomer of very high chemical resistance". 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. [50] The latter were largely empty because the collapse occurred on the eve of the Italian public holiday, Ferragosto. [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. The load of the bridge was 7,000 kg (15,000 lb) per tendon, while the tendons were originally capable of carrying 15,000 kg (33,000 lb)[citation needed].

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". Other than pre-stress, changes in geometry, such as corrosion in the tendons could impact the resonant frequency. 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. [16] As of the collapse of the bridge, only pillar 11 had been internally inspected in the 1990s, showing severed and oxidized strands. The bridge was designed by Riccardo Morandi. As little as a 2% shift could represent severe damage. It originated from the nearby Ferrometal company cameras, showing that both southern stays and locally attached road sections at pillar no. Viadukten blev opført mellem 1963 og 1967. Ingegnere Riccardo Morandi, … [17] The minutes of a February 2018 government meeting reported that resistance and reflectometry measurements had been performed indicating an "average" reduction of the cross section of 10 to 20% of the tendons. [47] As of 02:00 the following day (midnight UTC), 12 people were known still to be missing, and voices could be heard calling from underneath the debris; rescue efforts were continuing by floodlight using techniques commonly deployed after earthquakes. The remains of the original bridge were demolished in August 2019. ", "Repair of the stay cables of the Polcevera Viaduct in Genova, Italy", "Detail view – Part of reinforced pylon number 10. [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. Italia. 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. 1499 0 obj <> endobj 1542 0 obj <>/Encrypt 1500 0 R/Filter/FlateDecode/ID[<059944D3FC824B219E4D4571545A6508><92F1B297A7D64FB88ACA3CB98901BB95>]/Index[1499 64]/Info 1498 0 R/Length 157/Prev 1356109/Root 1501 0 R/Size 1563/Type/XRef/W[1 3 1]>>stream and in services for Basko Supermercati, painted in blue and green, became a widely publicised symbol of the disaster because it remained standing almost at the edge of the collapsed section.

The bridge is widely called "Ponte Morandi" after its structural designer, the noted engineer Riccardo Morandi.[2]. E l’abbiamo trovato. Presso l’Università degli Studi di Roma ebbe due cattedre: Tecnologia dei materiali e Tecnica delle Costruzioni. [11][21][36], In 2017, Carmelo Gentile and Antonello Ruccolo of the Polytechnic University of Milan studied the modal frequencies and deformations of the stays of the bridge. Anche quest’altro ingegnere, assistente di Morandi, durante la costruzione del ponte sulla laguna di Maracaibo (fra il 1957 ed il ’62) quando parlava del Maestro, lo faceva con occhi trasognati, giacché, come tanti allora e prima di allora, lo stimava capace di grandi imprese. From the movement of the top cross-beam, it appears the tension cables of the south-eastern stay gave way. 1 ottobre 2019 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. [94] The position of the Benetton family, whose company owns 30% of Atlantia, has also come under scrutiny. [73], Forty-three people were confirmed dead and 16 injured. Comments. On 3 May 2018, the Autostrade company had announced a call for tenders for a structural upgrade of the viaduct to the value of €20,159,000, with a deadline of 11 June 2018. [51], The initial hypotheses were that a structural weakness or a landslide caused the collapse. [13] This resulted in excessive deferred displacement of the vehicle deck so that it was neither level nor flat; at the worst points, it undulated in all three dimensions.

A Volvo FM truck belonging to Damonte Trasporti S.R.L. [41][43], By the mid-2000s, the A10 route through Genoa and over the bridge had become highly congested. 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. [41] Gentile had performed similar modal analyses on pillar 11 in the 1990s. [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. [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. [79] According to deputy minister of infrastructure Edoardo Rixi, the entire bridge would be demolished. [37] Modal frequencies were more than 10% different, specifically on the southern stays. 0 Love 9 Visits Published 8/31/2020. [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.

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. [18][19] Pillar 10 had the stays at the top strengthened with steel sheathing in the 1990s. It also provided a critical artery of European route E80, linking Italy and France. Dal 1971 è stato Research Professor presso l’Università Statale della Florida. Lo stato precedente della struttura dicono fosse pietoso. [citation needed], The viaduct was officially opened on 4 September 1967 in the presence of Italian President Giuseppe Saragat.

Per chiarirci le idee abbiamo cercato un tecnico in grado di spiegarci quanto è accaduto e quanto potrà accadere. One of the pioneers of modern engineering in Italy and the world disappears with him. 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. [87] Some of the victims' families refused to attend the service and instead hosted private funerals. [15] A single truck can weigh as much as 44,000 kg (97,000 lb). [20] Following the collapse, many questions have been raised about the stays. Dopo la strage, lo strazio: "Quando ero ministro...

Ma l’ingegnere, che per anni ha lavorato per società Autostrade, ha chiesto di mantenere l’anonimato. It connected Genoa's Sampierdarena and Cornigliano districts across the Polcevera valley. [81] On 16 August, the Lega Serie A postponed the opening 2018–19 Serie A matches for both Genoese association football clubs Genoa and Sampdoria that were originally scheduled for 19 August. [52] The bridge was reportedly undergoing maintenance at the time of the collapse, including strengthening the road foundations. Ha tenuto corsi di forma e strutture di ponti presso la facoltà di Architettura dell’Università di Firenze. Precipitati 30 auto e 3 tir: si cercano dispersi. I suoi studi sul calcestruzzo, vera ossessione, e tutte le leggerezze a cui andò incontro. [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. It was inaugurated on 3 August 2020. [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.

The Ponte Morandi bridge, named after its designer Riccardo Morandi, is part of the Polcevera viaduct and was a … Morandi design unusual at the time. 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. Morandi was, in fact, among the first to use concrete in the s and then the prestressed concrete. "Delrio, la cupa confessione. L'analisi ha il solo scopo di studiare gli sforzi e le deformazioni dell'intera opera. [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. Riccardo Morandi, oltre a concepire grandi opere infrastrutturali, nel corso della sua carriera fu dedito ad approfondire lo studio del calcestruzzo armato precompresso. [32][33] At no point was there a suggestion to reduce the load on the bridge. Images; Info; Comments; Analisi esplorativa del modello strutturale del Ponte del Polcevera di Genova. We all know how bad our infrastructure is in Italy. Ad alcuni, già noti, vengono addebitate nuove ipotesi di reato. In Genoa, in 2017, a confidential university report noted disparities in the behaviour of the stays of the now collapsed pillar 9. [65] There is speculation that lightning may have struck the stays, or a landslide could have destabilised the base. View La tragedia del Ponte Morandi images from our The collapse of the Morandi Bridge photo gallery. The crack may have indicated that the stay had stretched. [49], A large part of the collapsed bridge and the vehicles on it fell into the rain-swollen Polcevera. [7] In the 1990s, the tendons on pillar 11 appeared to be most damaged. [7][8] The concrete was prestressed only to 10 MPa,[citation needed] making it susceptible to cracks, water intrusion, and corrosion of the internal steel. Demolition began in February 2019[72] and was completed on 28 June 2019. [10] About 30% of the tendons had corroded away. Pylon 9 did not receive this upgrade", "Genova, crollo del ponte autostradale, nel mirino i cavi di cemento armato. 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. [96], The investigative committee was to be chaired by Roberto Ferrazza and to have as an expert member Antonio Brencich. [69] The family waited two days to release a company public statement offering condolences to victims and their families.[70]. [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. It was similar to his earlier 1957 design for the General Rafael Urdaneta Bridge in Venezuela,[5] except for the stays, which on the Venezuelan bridge are not covered with prestressed concrete.
