Morandi Bridge Collapse in Genoa, Italy  (1.5 PDH)

On 14 August 2018 at 11:35 AM, a relevant portion (about 243 m) of the viaduct over the Polcevera river in Genoa collapsed, killing 43 people. The bridge was designed in the early 1960s by Riccardo Morandi, a well-known Italian engineer, and opened to the public in 1967. The collapsed part of the bridge essentially comprised an individual self-standing structure spanning 171 m and two simply-supported connecting Gerber beam systems, each spanning 36 m from the self-standing structure to the adjacent portions of the bridge. This presentation aims to reminisce the complete story of the bridge, from the Italian construction boom in the 1960s to some of the issues that soon arose thereafter: the strengthening intervention in the 1990s, the subsequent structural monitoring and, finally, the strengthening project never brought to fruition.

Also potential reasons for the collapse are discussed. The explicit representation of complete structural collapse, and corresponding formation of debris, is still an open challenge in numerical modelling. However, recent applications have shown that the Applied Element Method (AEM) does appear to be able to capture adequately the progressive failure of both masonry, steel and RC structures. In this presentation, the AEM-based software tool Extreme Loading for Structures (ASI) has thus been employed with a view to numerically investigate potential failure mechanisms and triggering factors that might have contributed to the observed collapse of the Morandi bridge. To this end, the influence of several parameters, including corrosion induced deterioration of reinforcement in different locations of the bridge, have been assessed numerically through a sensitivity study.

Professor Roberto Nascimbene, PhD.

A structural engineer, he is the Head of the Building and Infrastructure Department in Eucentre; he is also an Adjunct Professor at the Faculty of Engineering - Pavia teaching two courses "Design of shells" and "Theory and Design of Steel Buildings".  He authored/coauthored more than one hundred scientific publications indexed in international journals, national magazines and conference proceedings; he co-authored three books, the first on shell structures, the second on existing precast structures and the third on temporary housing. He is a member of the technical committee of Eurocode 3, of the Regional Seismic Commission (Lombardia), of the Council of the Order of Engineers (Pavia) and of the Fabbriceria del Duomo of Pavia.  For more than ten years he has been the coordinator of professional training courses at Eucentre, organizing nearly a hundred seminars.  He has been involved, both for research but also for professional activities, in seismic vulnerability evaluations of industrial plants, reinforced concrete, steel, wood and precast buildings, tanks, robustness and progressive collapse of structures under extreme actions, modeling and advanced nonlinear numerical analyses.



Please register even though it's free so we can get an approximate headcount! We will be providing snacks and light refreshments.
