A COMPOSITE MODELLING APPROACH FOR THE RETROFITTING AND REHABILITATION OF AN HISTORICAL COASTAL ASSET

The Pont del Petroli pier is a coastal structure located in the town of Badalona, north Barcelona, Spain. was built 60s to allow mooring petroleum tankers, but fallen disuse 1990. Restored between 2003 and 2009, now regarded as historical social asset Catalan coast. In January 2020 storm Gloria (Amores et al., 2020), characterized by extreme wave conditions (recorded offshore significant heights excess 8.5 m) lasting for nearly two days, caused flooding events, casualties severe damages several structures head platform damaged, four supporting piles failed part footbridge beam washed away. There no recorded climate that hit so strong during its 50-year life. To reproduce led failure compositemodelling has been carried out at Universitat Politènica de Catalunya (UPC). outcomes work provide further insight information on interaction waves key elements (platform, footbridge, piles, pile caps) aided design structural retrofitting, including study different alternatives attached it.
