[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. Riccardo Morandi, oltre a concepire grandi opere infrastrutturali, nel corso della sua carriera fu dedito ad approfondire lo studio del calcestruzzo armato precompresso. [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. Un rotolo di acciaio da 3,5 tonnellate potrebbe essere la principale ragione del crollo del Ponte Morandi di Genova. Aperta inchiesta per omicidio e disastro colposi", "Quando il M5S parlava della "favoletta del ponte che sta per crollare" per bloccare la variante", "Quella "favoletta" sul rischio crollo del ponte che imbarazza i 5 Stelle, convinti "No Gronda". Viadukten blev opført mellem 1963 og 1967. [47] Between 30 and 35 cars and three trucks were reported to have fallen from the bridge. In Genoa, in 2017, a confidential university report noted disparities in the behaviour of the stays of the now collapsed pillar 9. Presso l’Università degli Studi di Roma ebbe due cattedre: Tecnologia dei materiali e Tecnica delle Costruzioni. 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? As little as a 2% shift could represent severe damage. I mages have emerged of the "crumbling" Ponte Morandi bridge in Genoa, a year before it collapsed killing 39 people. [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. Related Videos. 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. [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 Ponte Morandi bridge, named after its designer Riccardo Morandi, is part of the Polcevera viaduct and was a … 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. Inchiesta ponte Morandi, Schema del Quesito formulato dal giudice per accertare le cause del crollo. The crack may have indicated that the stay had stretched. [79] According to deputy minister of infrastructure Edoardo Rixi, the entire bridge would be demolished. [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. L’Ingegner Riccardo Morandi è stato a più riprese docente universitario. [17] On pillar 9 they could identify only four global modes, and the deformations of two of these identified modes were not fully compliant. According to the Corriere della Sera, this was the 11th bridge collapse in Italy since 2013. I nomi iscritti nel registro sono in tutto 74.

Eyewitnesses reported that the bridge was hit by lightning before it collapsed. [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]. [98] The research and imagery was forwarded to the Italian authorities for further evaluation. La Procura di Genova ha reso pubblica la lista aggiornata degli indagati per il crollo del ponte Morandi, del 14 agosto scorso.

The bridge was an engineering and architectural landmark since its construction. 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. [7] In the 1990s, the tendons on pillar 11 appeared to be most damaged. [51], The initial hypotheses were that a structural weakness or a landslide caused the collapse.

"Delrio, la cupa confessione. [66], In July 2019, a video showing the fall of the bridge was made public. 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. [53], It has been reported that the southern stays gave way explosively due to corrosion and damage. La costruzione del Ponte Morandi girato in 8mm. [73], Forty-three people were confirmed dead and 16 injured. 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. L'analisi ha il solo scopo di studiare gli sforzi e le deformazioni dell'intera opera. [10] About 30% of the tendons had corroded away. 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. [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. [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. %PDF-1.7 %���� 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… 3/�@�SS��R��7K��1e+���d �w�R�v��Te:�OReQ!��P�-�I��_�-~�&_ON�^WT9�~�B��X� ��136�h���ܭ&Q�/�䨧�����ٮ���m��� DN. h�bbd```b``���o��ɠ����$�db�`2L� � ��؄r���\�Pϣ"������9`�9�d�v �b��`�$�r0{ B�V�����D[�d�2��wDB��j��/d`bd`�h6���� �� endstream endobj startxref 0 %%EOF 1562 0 obj <>stream 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". Per chiarirci le idee abbiamo cercato un tecnico in grado di spiegarci quanto è accaduto e quanto potrà accadere. [96], The investigative committee was to be chaired by Roberto Ferrazza and to have as an expert member Antonio Brencich. 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). [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. [49], A large part of the collapsed bridge and the vehicles on it fell into the rain-swollen Polcevera. [90][91] Infrastructure investment in Italy was reduced dramatically after the 2008 financial crisis. 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. The remains of the original bridge were demolished in August 2019. [67] Immediately, the complete road on the pillar and soon after also the pillar itself fell. Il nome di Riccardo Morandi è assurto alla cronaca nera il 14 agosto 2018 a causa del crollo del viadotto che porta il … [95] Autostrade per l’Italia's chief executive, Giovanni Castellucci, said that the bridge would be rebuilt within eight months. The complete bridge was planned to be removed, along with multiple houses in the surrounding area. 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]. E l’abbiamo trovato. We all know how bad our infrastructure is in Italy. [41] Gentile had performed similar modal analyses on pillar 11 in the 1990s. [71], It was later decided that the bridge would not be repaired but demolished. [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. The steel sheathing has been added 1993 and later. Images; Info; Comments; Analisi esplorativa del modello strutturale del Ponte del Polcevera di Genova. The bridge is widely called "Ponte Morandi" after its structural designer, the noted engineer Riccardo Morandi.[2]. 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.

Ma l’ingegnere, che per anni ha lavorato per società Autostrade, ha chiesto di mantenere l’anonimato. It was inaugurated on 3 August 2020. [85][86], A state funeral was held on 18 August, inside the Fiera di Genova event arena, for 18 victims of the collapse, along with recognition for the firefighters and other rescue workers. "[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. [17] From 1990 onward, the easternmost pillar 11 had its stays strengthened by flanking them with external steel cables. [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. Deputy Prime Minister Luigi Di Maio claimed that they were "definitely to blame. [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. Demolition began in February 2019[72] and was completed on 28 June 2019. [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. One of the pioneers of modern engineering in Italy and the world disappears with him. View La tragedia del Ponte Morandi images from our The collapse of the Morandi Bridge photo gallery. 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 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. Lo stato precedente della struttura dicono fosse pietoso. [30] Traditionally, bridges were designed only for a 50-year life span;[23] the bridge failed just under 51 years after its opening. [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. 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. L’ingegnere Riccardo Morandi, progettista del ponte crollato a Genova, era considerato uno dei massimi esperti nel settore. A Volvo FM truck belonging to Damonte Trasporti S.R.L. Morandi was, in fact, among the first to use concrete in the s and then the prestressed concrete. 0 Love 9 Visits Published 8/31/2020. [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.

[46][74], Multiple survivors were transported to nearby hospitals, many in critical condition. 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. Infrastrutture. [69] The family waited two days to release a company public statement offering condolences to victims and their families.[70]. [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 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. [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. 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).
