[51], The initial hypotheses were that a structural weakness or a landslide caused the collapse. Lei che è stato più volte ospite nelle reti nazio-nali, in cui è stato sempre richiamato il concetto di “errore di Morandi”, cosa ha pensato di questa eventualità? The complete bridge was planned to be removed, along with multiple houses in the surrounding area. 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. 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. [41] Gentile had performed similar modal analyses on pillar 11 in the 1990s. [75][76], The area under the remaining part of the bridge, including several homes, was evacuated. The bridge is widely called "Ponte Morandi" after its structural designer, the noted engineer Riccardo Morandi.[2]. We all know how bad our infrastructure is in Italy. Ponte Morandi: sul tragico crollo del viadotto di Genova, che ha causato 43 vittime, si sta sentendo di tutto. It was inaugurated on 3 August 2020. 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. [30] On 23 August 2018, Brencich resigned from the inspection commission, and Minister Danilo Toninelli removed Ferrazza as the chair, for "reasons of opportunity in relation to all the institutions involved in this affair".[97].

As little as a 2% shift could represent severe damage. It also provided a critical artery of European route E80, linking Italy and France. [95] Autostrade per l’Italia's chief executive, Giovanni Castellucci, said that the bridge would be rebuilt within eight months. Ingegneria. [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. Dal 1971 è stato Research Professor presso l’Università Statale della Florida. [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. Riccardo Morandi, oltre a concepire grandi opere infrastrutturali, nel corso della sua carriera fu dedito ad approfondire lo studio del calcestruzzo armato precompresso. [18][19] Pillar 10 had the stays at the top strengthened with steel sheathing in the 1990s. [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.

[42] Other related methods were applied on the stays of Ponte Morandi in the 1990s, such as reflectometry, which was able to measure the tension but not strength of the tendons. Morandi was, in fact, among the first to use concrete in the s and then the prestressed concrete. [98] The research and imagery was forwarded to the Italian authorities for further evaluation. The bridge was an engineering and architectural landmark since its construction. [90][91] Infrastructure investment in Italy was reduced dramatically after the 2008 financial crisis. [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. [88], In mid-2020, control of the infrastructure company was given back to the government after legislations had reduced the penalty for changing the ownership structure. The city council requested proposals for improvement of traffic flow through Genoa, with the Autostrade company in 2009 proposing the "Gronda di Ponente" project to improve flow, by moving traffic to a newly built Autostrada interchange system located to the north of the city.

[46][74], Multiple survivors were transported to nearby hospitals, many in critical condition. From the movement of the top cross-beam, it appears the tension cables of the south-eastern stay gave way. [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. The dead were 29 citizens of Italy, four from France, three from Chile, two from Albania and one each from Colombia, Jamaica, Moldova, Peru, and Romania. [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. Nel corso delle indagini sul crollo del ponte Morandi, il viadotto collassato lo scorso 14 agosto causando la morte di 43 persone, si cercò di intralciare le indagini. [23][24][25][26][27], The then-minister of infrastructures and transport Graziano Delrio, who was in charge until 1 June 2018, was informed several times during 2016 in the Italian parliament that the Morandi bridge needed maintenance.[28][29]. 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 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. The Ponte Morandi bridge, named after its designer Riccardo Morandi, is part of the Polcevera viaduct and was a … 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. [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. Per chiarirci le idee abbiamo cercato un tecnico in grado di spiegarci quanto è accaduto e quanto potrà accadere. La costruzione del Ponte Morandi girato in 8mm.

When a 210 metres (690 ft) section of the viaduct collapsed during a rainstorm on 14 August 2018, 43 people died — leading to a yearlong state of emergency in the Liguria region, extensive analysis of the structural failure[3] and widely varying assignment of responsibility. Italiano: Immagine del Ponte Morandi, dopo il crollo avvenuto il 14 agosto Visuale da Est presso lo svincolo di Genova Ovest. [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. Ingegnere Riccardo Morandi, … [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. [65] There is speculation that lightning may have struck the stays, or a landslide could have destabilised the base. [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. Il suo lavoro inoltre gli valse due lauree Honoris Causa: una presso l’Università di Monaco di Baviera e una presso l’Università degli Studi di Reg… 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]. Demolition began in February 2019[72] and was completed on 28 June 2019. Ha tenuto corsi di forma e strutture di ponti presso la facoltà di Architettura dell’Università di Firenze. [67] Immediately, the complete road on the pillar and soon after also the pillar itself fell. [73], Forty-three people were confirmed dead and 16 injured. I suoi studi sul calcestruzzo, vera ossessione, e tutte le leggerezze a cui andò incontro. The funeral was attended by Italian politicians, such as President Sergio Mattarella, Prime Minister Giuseppe Conte, interior minister Matteo Salvini, transport minister Danilo Toninelli, and the secretary of the Democratic Party Maurizio Martina. [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". "Delrio, la cupa confessione. [83][84], Governor Giovanni Toti said that the loss of the bridge was an "incident of vast proportions on a vital arterial road, not just for Genoa, but for the whole country".

[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. 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. E l’abbiamo trovato. [10] About 30% of the tendons had corroded away.

[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. The bridge was designed by Riccardo Morandi. Morandi design unusual at the time.

L'analisi ha il solo scopo di studiare gli sforzi e le deformazioni dell'intera opera. 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. Un rotolo di acciaio da 3,5 tonnellate potrebbe essere la principale ragione del crollo del Ponte Morandi di Genova. 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. Only after continual measurement, redesign and associated structural work was the vehicle deck considered acceptable, approaching horizontal by the mid-1980s. 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.

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. 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".

[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. Scientists from NASA's Jet Propulsion Laboratory in Pasadena, California, developed a method of analyzing satellite data to detect millimeter-size changes. [20] Following the collapse, many questions have been raised about the stays. A rail replacement bus service was established between the stations. The disaster caused a major political controversy about the poor state of infrastructure in Italy and raised wider questions about the condition of bridges across Europe. 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). [71], It was later decided that the bridge would not be repaired but demolished. 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.

It originated from the nearby Ferrometal company cameras, showing that both southern stays and locally attached road sections at pillar no. [17] On pillar 9 they could identify only four global modes, and the deformations of two of these identified modes were not fully compliant. [30][31] A crack in the road had appeared at least 14 days before the collapse, near the south-eastern stay of the subsequently-collapsed pillar 9.
