Santa Maria della neve. Laser scanning per la conservazione
Il volume raccoglie le attività ed i risultati del workshop internazionale sul tema “Il rudere: ricostruzione vs conservazione?” svoltosi nel 2011 nell’ambito del programma di ricerca sottoscritto dall’Università “G. d’Annunzio” di Chieti-Pescara e l’Universitate de Arhitectura ̆ s ̧i Urbanism “Ion Mincu” di Bucarest, nonché i contributi che studiosi di diverse istituzioni, italiane e straniere, hanno voluto apportare al tema oggetto di studio. In appendice sono stati presentati gli esiti progettuali cui sono pervenuti i partecipanti al workshop su “Il restauro del tempio di S. Maria della neve a Cascia (PG)”. Il contributo descrive, le fasi, le scelte e le difficoltà incontrate, nell'applicazione delle avanzate tecniche di rilevamento, basate sulla fotogrammetria ed il laser scanning, finalizzate all'acquisizione di dati quantitativamente certi sulla geometria delle strutture e qualitativamente validi sullo stato degli affreschi in pessimo stato di conservazione. L'integrazione dei dati strumentali ha prodotto un modello 3D particolarmente efficace nel trasmettere con grande realismo le forme e le criticità; e supportare la pianificazione degli interventi e progetti
Tecnologie Geomatiche integrate per la documentazione, conservazione e valorizzazione del Patrimonio. Il caso di studio della Chiesa della Madonna della neve in località Aremogna a Roccaraso (AQ).
Lo studio nasce e si sviluppa all'interno del Dipartimento di Architettura di Pescara, nell'ambito di una ricerca multidisciplinare che vede impegnate la Geomatica e la Storia dell'Architettura e riguarda lo studio storico-conservativo di Beni Architettonici risalenti alla seconda metà del Novecento di chiara ispirazione corbuseriana nella zona di Sulmona e dell'Alto Sangro. Il contributo si sviluppa intorno ad un tema molto discusso e di grande attualità: la ricostruzione virtuale 3D, come valido supporto per orientare la conoscenza, la catalogazione, il restauro, la ricostruzione e la valorizzazione dei monumenti e del costruito storico. In particolare, rivolge l'attenzione all'apporto delle sempre più raffinate e accurate tecniche che fanno capo alla Geomatica per cercare andare oltre gli attuali livelli di rappresentazione visiva per sostenere l'integrazione ed il collegamento delle informazioni interdisciplinari, attraverso lo sviluppo di nuovi strumenti e metodi per la modellazione 3D. E' stato proposto un sistema di procedure tradizionali ed avanzate, economiche ed efficaci, per una modellazione facilmente comprensibile e divulgabile, realizzata sulla base di formati standard, in modo da favorire l'interoperabilità tra le varie competenze interagenti
Traditional measured drawing vs advanced 3d scanning for the protection of cultural heritage: a research and teaching programme
This paper gives an account on the aims, methods and progress of the joint research developed by the ???Gabriele d???Annunzio??? University of Chieti ??? Pescara and the ???Ion Mincu??? University of Architecture and Urbanism of Bucharest, on the confrontation of traditional and recent digital techniques of investigation and survey of historic built structures, in view of their better understanding, interpretation and, ultimately, conservation. Of the several individual objects used as case studies within the research programme, two buildings were selected to support the present account: the late 17th century Palace of Constantin Brâncoveanu at Potlogi (Dâmbovi??a County) and the early 20th century Cantacuzino Palace at Flore??ti (Prahova County), both in Romania.
The research on investigation and survey methods and techniques is part of a wider and sustained joint action of our architecture schools, developed over the past six years through alternate field- and studio workshops, organized both in Romania and Italy, on several monuments with different biography and pathology, involving mixed groups of Romanian and Italian students and faculty members. The teaching and research process is going through a number of phases, adapting to the specificity of each individual case, from field survey ??? including information gathering on morphology, structure, condition and active processes, but also on physical and social context ??? through critical analysis, to conservation planning.
The two monuments chosen for the present contribution are very significant for one particular programme of the historic architecture of Wallachia, the noble residences, and are both well-known and featured in all important architecture histories. One of the palaces, the one in Potlogi, has undergone a major restoration led by an outstanding figure of Romanian architectural conservation, ??tefan Bal??, while the other palace, in Flore??ti, has had an unusual destiny, of perpetual ruination, which began before the building was even completed.
The aims of research started from the need of an accurate and detailed knowledge of the buildings, to include a thorough architectural and structural description, and an extended account on the transformations ??? brought by subsequent interventions or by ruination ??? and processes of deterioration. Further, the need to devise the most appropriate representation methods was considered. Within the overall study programme, the approach of the two monuments also aimed at the discussion of conservation scenarios and plans, but these exceed the purpose of the present account.
The investigation and survey methods applied included on-site direct analysis and discussion, and data gathering through traditional techniques (sketches, hand-measurements and drawings) and through advanced technologies (3d laser scanning, photogrammetry and unmanned aerial vehicle photography). The results of the new surveys are confronted with existing representations of the two buildings: pictures, artworks, photographs, and ??? firstly ??? measured drawings from previous documentation or restoration campaigns, featured in publications of kept in archives. By the joint use of traditional and advanced techniques and technologies, and by the confrontation with previous graphic documentation, the knowledge value of the exercise emerge: it provides exhaustive and highly accurate information on the physical state of the buildings and it allows a more extensive and better understanding of the structures, of their particular features and their history and transformations. Ultimately, such knowledge makes the premise for a good conservation project. The educational value of the exercise is no less important, as it allows the students to assess the different methods and techniques available, and to be able to plan accordingly in their future standing as practicing architects, possibly active in the field of research and conservation. A few of the participants to the workshops chose to continue this experience into their graduation projects.
The planning of actual work on the two monuments, as in other cases studied within the joint Italian-Romanian workshops, comprised several steps, with a first one for the definition of working methods and selection of techniques, followed by one or more sessions of field work, for the acquisition of data and later by a series of working sessions for data processing and representation. At same time, a confrontation of previous graphic representations and the new comprehensive and detailed 3d models took place. Now we are in the final phase, of complex morphological analysis on the 3d models and other graphical materials, which has already brought up significant information, likely to enhance the understanding of the history of the two monuments, and, hopefully, to contribute to their effective conservation
AN INTEGRATED MULTIDISCIPLINARY DIAGNOSTIC APPROACH FOR SEISMIC AND FUNCTIONAL REHABILITATION OF “ERMETE NOVELLI” THEATRE IN GROTTAZZOLINA
The recent Central Italy Earthquake damaged the "Ermete Novelli" Theatre in Grottazzolina: an early XX century masonry building. The building is classified as relevant Cultural Heritage Building both for architectural contents and functional aims. For these reasons it was under both structural assessment evaluation before the Earthquake event and functional rehabilitation design. The seismic response was different on respect of expected behaviour. A new comprehensive (geometrical, geotechnical, structural, acoustic, thermal and architecture) study of the building was commissioned. In particular both Architecture and Engineering Departments of Chieti-Pescara University are involved in this analysis. An integrated multidisciplinary diagnostic approach was defined and carried out
Valutazione della stabilità spondale di un tratto in forte erosione del fiume Vomano (TE) mediante analisi 3D alle differenze finite.
Banking stability evaluation along the Vomano river (Teramo – central Italy), by 3D numerical modelling
ABSTRACT: This job deal with the banking system evolution along the Vomano river (Teramo province in Abruzzo
Region). Due to river deepening the riverbed is characterized from banking instability. Embankments, nearly vertical, with
over ten meters high escarpment, are withdrawing constantly due to the decreasing of clay borders caused by stream. The
focused area is composed by a clay substratum highly engraved appearing along the main part of the river, and from alluvial
cover. Morphology is continuously modified. In order to get the right assessment of the present situation a topographic
survey has been realized by the use of GPS (Global Positioning System) a powerful tool which permits quick surveys, high
performances and working simplicity. The survey has been realized using the equipment Trimble Total Station 5700, on
mode RTK, which guaranteed an appropriate precision for the riverbeds. The obtained data, bearing the topographic area,
has been elaborated according several software concerning the construction of geometric model. Physical-mechanical
feature of lithotypes obtained from lab analysis, have been used to get physic model. This model has been finally discretized
in order to figure out the correct value of the volume involved in the embankment instability. Furthermore, to achieve the
purpose to analyse the cinematic evolution was employed a three dimensional finite difference numerical code.
Key terms: GPS, banking instability, 3D modelling, Abruzzi region
Termini chiave: GPS, instabilità spondale, modellazione numerica, regione Abruzz
Il ponte della Badia di Vulci. Storia rilievo, progetto e intervento di restauro strutturale
Nel 2012 alcune inondazioni particolarmente intense del fiume Fiora hanno danneggiato il ponte
della Badia nel Parco Archeologico di Vulci, che si trova tra Canino e Montalto di Castro. L’alluvione
ha danneggiato la struttura del fiume, portando via porzioni di muro alla base del pilone destro, e
trascinandole a valle. Le sezioni superstiti del pilone ora sono più piccole e le connessioni a muro
sono state fortemente influenzate. In particolare, la violenza dell’inondazione ha “strappato” lo
strato protettivo esterno, rendendo il pilone più vulnerabile a un ulteriore deterioramento.
Il ponte, che è noto come “Ponte dell’Arcobaleno”, insieme alla stretta gola scavata dal fiume e al
castello dell’abbazia, formano una splendida vista panoramica che è stata disegnata da pittori e
descritta da viaggiatori come George Dennis e David Herbert Lawrence.
Attraversa il Fiume Fiora in un punto in cui gli argini sono molto vicini tra loro, ma sebbene
questa caratteristica abbia permesso la sua costruzione in epoca etrusca, durante le inondazioni
il ponte restringe l’alveo laddove la corrente accelera fortemente. Ciò crea una criticità aggravata
dall’ulteriore ostacolo di enormi massi, caduti dalle sponde ripide nel letto del fiume.
Nella prospettiva di un restauro, il ponte è stato meticolosamente esaminato per determinarne
le caratteristiche costruttive e i materiali utilizzati. Questo studio ha incluso anche la storia della
struttura, dai tempi più remoti a periodi relativamente recenti, quando ha subito un notevole
restauro.
Come detto, il pilone destro è la parte del ponte più danneggiata dall’alluvione. Fortunatamente
la forma della sponda del fiume in quel punto rende facile la costruzione di strutture temporanee
per il restauro, che per ragioni di sicurezza dovrebbe essere completato in un brevissimo lasso di
tempo, durante il periodo in cui le alluvioni sono statisticamente meno ricorrenti.
Per questi motivi e anche per i limitati fondi messi a disposizione dalla Soprintendenza dell’Etruria
Meridionale, nella prima fase, il restauro si è concentrato sulla reintegrazione del pilone destro
Numerical modeling and hazard of a cliff in anthropic and historical contexts
The paper deals with a numerical modelling applied for the evaluation of the static and dynamic
stability of a limited rock shore strip located in Peschici, a small city along the Gargano promontory (Southern
Italy), very important by a tourist and historical points of view.Thus a considerable effortwas spent to numerically
evaluate both probable and just only potential rock landslides. The Gargano promontory is characterized by a
wide spread of different land morphologies like cliffs, coves, bays. Thus, for the aim of this paper, Peschici’s
cliff has been selected for which the highest geo hazard has been ascribed. The study has been carried out
through firstly a geo-mechanical survey to recognize the discontinuity families, implemented by a terrestrial
laser scanner survey, and after with a numerical modelling applying a 2D code (UDEC 6.0). The results allowed
the identification of areas at most risk of collapse for the protection of the safety of the inhabitants
Parameters of the 2016 central Italy earthquake surface faulting (M 6.5, normal fault) and comparison with global data
We present the parameters of the surface faulting that formed during the 2016 earthquakes in central Italy
(maximum magnitude = 6.5), obtained thanks to direct field survey. The obtained parameters (SRL, AD calculated with
different methods, MD, D/MD, D/AD, AD/MD) are compared with global data compiled and analysed in various works in the
literature. A comparison with the values predicted by well-established empirical regressions is performed as well. The
differences are open to discussio
