Resilience and sustainability assessment of a prestressed concrete viaduct
The paper explores Greece’s Polyfytos viaduct, the nation’s second-longest bridge spanning 1,372 meters, renowned also for providing access to key power plants in South-East Europe. A resilience analysis of different retrofitting scenarios was conducted, including both transitability and structural capacity aspects, employing visual inspections, digital data collection, and advanced modeling techniques. The viaduct, conceptualized by Prof Riccardo Morandi and built in 1972-1975, displays typical degradation seen in prestressed and reinforced concrete bridges. Unlike previous research focused solely on retrofitting with LCA and LCC assessments, this study integrates resilience assessment, marking a pioneering holistic approach to viaducts refurbishment
Un punzone per decorazione ceramica da Fest\uf2s
A clay stamp was found by chance in the Haghia Photini quarter, located to the north of the Minoan Palace of Phaistos. The stamp, reproducing an 11-petal rosette and a very thin tongue, was surely used for pottery decoration; thanks to the characteristics of the two decorative motifs, a Hellenistic chronology is proposed. It might be good evidence for pottery production at Phaistos during the Hellenistic age
