ingegnere del ponte morandi

[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. Per chiarirci le idee abbiamo cercato un tecnico in grado di spiegarci quanto è accaduto e quanto potrà accadere. From the movement of the top cross-beam, it appears the tension cables of the south-eastern stay gave way. [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". Precipitati 30 auto e 3 tir: si cercano dispersi. The bridge is widely called "Ponte Morandi" after its structural designer, the noted engineer Riccardo Morandi.[2]. It had a length of 1,182 metres (3,878 ft), a height of 45 metres (148 ft) at road level, and three reinforced concrete pylons reaching 90 metres (300 ft) in height; the maximum span was 210 metres (690 ft). Presso l’Università degli Studi di Roma ebbe due cattedre: Tecnologia dei materiali e Tecnica delle Costruzioni. 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. Il nome di Riccardo Morandi è assurto alla cronaca nera il 14 agosto 2018 a causa del crollo del viadotto che porta il … [17] On pillar 9 they could identify only four global modes, and the deformations of two of these identified modes were not fully compliant. [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]. 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. [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. [100], The collapsed section of the Ponte Morandi, CS1 maint: multiple names: authors list (, In the Venezuelan bridge the stays was not covered with prestressed concrete, "Expert reaction to Genoa motorway bridge collapse", "La storia del Ponte Morandi: un tempo avveniristico, ma non mancavano criticità", "Crollo Genova, trovato l'ultimo disperso sotto le macerie: è l'operaio Mirko. L’Ingegner Riccardo Morandi è stato a più riprese docente universitario. A Volvo FM truck belonging to Damonte Trasporti S.R.L. [98] The research and imagery was forwarded to the Italian authorities for further evaluation. [94] The position of the Benetton family, whose company owns 30% of Atlantia, has also come under scrutiny. One of the pioneers of modern engineering in Italy and the world disappears with him. 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. La Procura di Genova ha reso pubblica la lista aggiornata degli indagati per il crollo del ponte Morandi, del 14 agosto scorso. The effects would be reduced by the composite nature of the stays when observing global modes. Scientists from NASA's Jet Propulsion Laboratory in Pasadena, California, developed a method of analyzing satellite data to detect millimeter-size changes. [53], It has been reported that the southern stays gave way explosively due to corrosion and damage. [50] The latter were largely empty because the collapse occurred on the eve of the Italian public holiday, Ferragosto. Ma l’ingegnere, che per anni ha lavorato per società Autostrade, ha chiesto di mantenere l’anonimato. 0 Love 9 Visits Published 8/31/2020.

[17] From 1990 onward, the easternmost pillar 11 had its stays strengthened by flanking them with external steel cables. 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. View La tragedia del Ponte Morandi images from our The collapse of the Morandi Bridge photo gallery. 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 work on the reinforcement of the stays on pillars 9 and 10 would have needed to be finished within five years. Eyewitnesses reported that the bridge was hit by lightning before it collapsed. 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. [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. 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. A rail replacement bus service was established between the stations. [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. Ad alcuni, già noti, vengono addebitate nuove ipotesi di reato. 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. comment. 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. [87] Some of the victims' families refused to attend the service and instead hosted private funerals. 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. The replacement bridge, the Viadotto Genova-San Giorgio ("Genoa-Saint George Viaduct") was inaugurated in August 2020.[4]. [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. %PDF-1.7 %���� Italiano: Immagine del Ponte Morandi, dopo il crollo avvenuto il 14 agosto Visuale da Est presso lo svincolo di Genova Ovest. Ingegneria. According to the Corriere della Sera, this was the 11th bridge collapse in Italy since 2013. [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". [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. "[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. [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. 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).

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. [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. We all know how bad our infrastructure is in Italy. Inchiesta ponte Morandi, Schema del Quesito formulato dal giudice per accertare le cause del crollo. [20] Following the collapse, many questions have been raised about the stays. L’ingegnere Riccardo Morandi, progettista del ponte crollato a Genova, era considerato uno dei massimi esperti nel settore. [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. [49], A large part of the collapsed bridge and the vehicles on it fell into the rain-swollen Polcevera. [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. [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.

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. Romano Amodeo 38,783 views. [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. [65] There is speculation that lightning may have struck the stays, or a landslide could have destabilised the base. 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. 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". [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. Riccardo Morandi, oltre a concepire grandi opere infrastrutturali, nel corso della sua carriera fu dedito ad approfondire lo studio del calcestruzzo armato precompresso.

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. The remains of the original bridge were demolished in August 2019. [7] In the 1990s, the tendons on pillar 11 appeared to be most damaged. 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. The steel sheathing has been added 1993 and later. [66], In July 2019, a video showing the fall of the bridge was made public.

Ingegnere Riccardo Morandi, chi è: padre del ponte crollato ieri a Genova. It also provided a critical artery of European route E80, linking Italy and France. The crack may have indicated that the stay had stretched. [47] Between 30 and 35 cars and three trucks were reported to have fallen from the bridge. [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. [31][38] In pre-stressed concrete beams, such a difference could represent the entire effect of the non-linear pre-stresses. Ingegnere Riccardo Morandi, … [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. [21] In 1979/1980, Morandi's similar[22] bridge in Venezuela suffered one or more stay cable failures with collapse imminent. It originated from the nearby Ferrometal company cameras, showing that both southern stays and locally attached road sections at pillar no. 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 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.
