A Novel Numerical Tool for Seismic Vulnerability Analysis of Ruins in Archaeological Sites

Stefano Galassi

Ancient masonry constructions in archaeological sites are often ruins or remains of wider portions. Therefore, archaeological artifacts generally occur as a discontinuous set of walls or columns detached from the original context. The absence of most of the original structural portions makes them much more vulnerable. Indeed, even if their current existing condition is an indicator of their equilibrium condition under gravitational loads, this condition is not sufficient to guarantee their preservation in the case of an unexpected earthquake. Furthermore, the cracking patterns and collapses make them even more vulnerable. For these reasons, the vulnerability of ruins should be addressed as regard to the possible failure mechanisms that can be activated by seismic actions. Accordingly, in this article a novel and targeted numerical tool for seismic vulnerability assessment of remains in archaeological sites, that considers collapse mechanisms occurrence as the main cause of masonry constructions being lost, is presented. Results of the numerical procedure proposed are compared with the results obtained by the canonical formulation of virtual works. Finally, the seismic vulnerability level of selected masonry constructions in the archaeological sites of Pompeii and Arpino (Italy) has been assessed by the use of this procedure.

Non-Destructive Multi-Analytical Approach to Study the Pigments of Wall Painting Fragments Reused in Mortars from the Archaeological Site of Pompeii (Italy)

During the excavations carried out in Via di Mercurio (Regio VI, 9, 3) in Pompeii, in 2015, some red, green, black, and brown wall painting fragments were found in the preparatory layer of an ancient pavement which was probably built after the 62 AD earthquake. These fragments, derived from the rubble, were used as coarse aggregate to prepare the mortar for building the pavement. The wall painting fragments are exceptionally well preserved, which is an uncommon occurrence in the city of Pompeii. However, as they were enclosed in the mortar, the wall painting fragments were protected from the high temperatures (probably ranging between 180 °C and 380 °C) produced by the eruption in 79 AD. The pigmented outer surface of each sample was analyzed using a non-destructive multi-analytical approach, by combining spectrophotometric colorimetry and portable X-ray fluorescence with micro-Raman spectroscopy. The compositional characterization of the samples revealed the presence of cuprorivaite, goethite, and celadonite in the green pigments; hematite in the red pigments; goethite in the brown pigment; and charcoal in the black pigment. These data probably provide us with the most “faithful picture” of the various red, green, black, and brown pigments used in Pompeii prior to the 79 AD eruption.

Pompeii’s Stabian Baths. Mechanical behavior assessment of selected masonry structures during the 1st century seismic events

Giacomo Tempesta

The eruption of Mount Vesuvius in 79 AD buried and preserved the Stabian Baths building in the exact configuration which the archaeological excavations carried out in the second half of the 19th century recovered. By combining archeologists’ studies with the analysis of deformations and cracking pattern due to the 1st century seismic events, in this article numerical models have been formulated which allowed the formation of some hypotheses coherent on the timeline of the events, the damage to as well as the change of the shape and stylistic language of the thermal building. Specifically, through global seismic analyses and kinematic analyses of masonry portions of the “destrictarium” block, it is proven that during the 1st century not only a sole catastrophic earthquake occurred but, at least, two important seismic events took place. The purpose of this article is to identify and parameterize the responsible earthquake by the analysis of seismic effects detectable in the damages and archaeological remains of the masonry walls of the Stabian Baths. The identification of the earthquake and the grading of provoked damages represent a useful knowledge tool that provides information about the vulnerability of ancient buildings and can be suitably used also to safeguard architectural heritage from seismic risk.

About Me

Nicola Ruggieri, Ph.D., is an architect who specializes in historical timber structures and construction history. He was the Italian delegate at the EU-COST ACTION FP1101/Assessment, Reinforcement and Monitoring of Timber Structures (Trento, London, Antalya, Praga, Trondheim, Wroclaw). He was member of the scientific committee of numerous international conference (HEaRT, Cosenza, 2013, Lisbon, 2015; RIPAM 8.5, Florence, 2020; YOCUCO Matera, 2018). He is the author of more than 100 publications (monographs, scientific articles, conference papers, editorships) and has taught at the University of Calabria, Sapienza of Rome, Roma Tre, Florence, Naples and Perugia. Since 2016, he is visiting Professor at the 2nd Level Master of Seismic Structural Improvement, Restoration and Repair of Historical Buildings, University of Ferrara, Italy. From 2015 to 2018, he was member of the Segreteria Tecnica di Progettazione of the Parco Archeologico di Pompei. Since 2019, he is expert member of International Scientific Committee on the Analysis and Restoration of Structures of Architectural Heritage (ISCARSAH) – ICOMOS and of International Wood Committee (IIWC) – ICOMOS. He was the author of many projects on Architectural Heritage (i.e. Cathedral of Catanzaro; Cathedral of Cosenza; Ex Real Polverificio Borbonico of Scafati; Monumental Tomb of Porta Stabia, Pompeii; Insula Meridionalis, Pompeii). Since 2018 he is official of the Italian Ministery of Cultural Heritage.
