"Delrio, la cupa confessione. [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. [18][19] Pillar 10 had the stays at the top strengthened with steel sheathing in the 1990s. [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. As little as a 2% shift could represent severe damage. 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. Infrastrutture. [98] The research and imagery was forwarded to the Italian authorities for further evaluation. 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]. [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".

La costruzione del Ponte Morandi girato in 8mm. Ingegnere Riccardo Morandi, … 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. La Procura di Genova ha reso pubblica la lista aggiornata degli indagati per il crollo del ponte Morandi, del 14 agosto scorso. 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). comment.

From the movement of the top cross-beam, it appears the tension cables of the south-eastern stay gave way.

[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. [41] Gentile had performed similar modal analyses on pillar 11 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.

The steel sheathing has been added 1993 and later. [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. [17] From 1990 onward, the easternmost pillar 11 had its stays strengthened by flanking them with external steel cables. [20] Following the collapse, many questions have been raised about the stays. L’Ingegner Riccardo Morandi è stato a più riprese docente universitario. [21] In 1979/1980, Morandi's similar[22] bridge in Venezuela suffered one or more stay cable failures with collapse imminent. 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. Dal 1971 è stato Research Professor presso l’Università Statale della Florida. Images; Info; Comments; Analisi esplorativa del modello strutturale del Ponte del Polcevera di Genova. [10] About 30% of the tendons had corroded away. Other than pre-stress, changes in geometry, such as corrosion in the tendons could impact the resonant frequency.

The bridge was an engineering and architectural landmark since its construction. One of the pioneers of modern engineering in Italy and the world disappears with him. The work on the reinforcement of the stays on pillars 9 and 10 would have needed to be finished within five years. L’ingegnere Riccardo Morandi, progettista del ponte crollato a Genova, era considerato uno dei massimi esperti nel settore. Locals have posted images of the bridge … Deputy Prime Minister Luigi Di Maio claimed that they were "definitely to blame. Morandi was, in fact, among the first to use concrete in the s and then the prestressed concrete. [39][40] The pre-stress in the Ponte Morandi was characterised as relatively small from the start. The Ponte Morandi bridge, named after its designer Riccardo Morandi, is part of the Polcevera viaduct and was a … 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. [7] In the 1990s, the tendons on pillar 11 appeared to be most damaged. [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. [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.

[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. 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. [37] Modal frequencies were more than 10% different, specifically on the southern stays. [87] Some of the victims' families refused to attend the service and instead hosted private funerals.
