Il restauro della chiesa santa Maria maggiore della pietrasanta. Applicazione delle biotecnologie
No full textLa chiesa di Santa Maria Maggiore della Pietrasanta fu progettata da Cosimo
Fanzago tra il 1653 e il 1667 e sorge sulle rovine di una basilica eretta da
Pomponio, vescovo di Napoli, tra il 514 e il 532 nel centro storico di Napoli. La
presenza di un'antica pietra sacra, con una croce incisa, ha dato origine alla
denominazione più comune di Chiesa della Pietrasanta
In questo articolo, gli autori, dopo una descrizione dettagliata delle tecnologie,
innovative e tradizionali, per il restauro, illustrano criticamente le tecnologie
applicate all'ipogeo, agli stucchi e ai dipinti della Chiesa su tela, evidenziando i
risultati raggiunti
MARKET SQUARE IN NAPLES HISTORICAL ANALYSIS OF THE SITES FOR A PROPOSAL OF ARCHITECTURAL RECOVERY AND URBAN REGENERATION
Full text linkIn this paper it is presented a search for architectural restoration and urban redevelopment of the Market Square in Naples.
What is common to the Anjou, the Masaniello revolution and Ferdinand IV of Borbone with the architect Francesco Sicuro? A square, Piazza Mercato, which for many centuries was a beat-ing heart of Naples and Neapolitans.
This great City shopping center, opened in 1270 by Charles I of Anjou, after the first post-war period has been affected by a slow decline that brought the wonderful square to become a huge parking lot and saw the eitht-century fountains that adorn subjected to constant vandalism. To-day in the Market Square, as in many other places and here perhaps more than others, it is spectacularly photographed the historical stratification: there coexist the speculation of the fif-ties and sixties and the survival of quality architecture.
A set, therefore, of great historical, urban, architectural and social that today is in a state of disrepair and has largely lost its ancient and vibrant shopping destination and trade.
In this arrangement it becomes import the disproportionate volume of Palazzo Ottieri that if one side has denied the sea, on the other hand has strengthened the market castrum character.
The research is divided into three phases: 1 “History”, which is conducted in-depth historical analysis of the sites; 2 “The existing Town Planning Tools”, which is studied either both the urban layout of the place or the set of existing planning instruments; 3 “The Project”, in which we propose a hypothesis building restoration of the facades and regeneration hypothesis of places to return to the square its former main function, that of “THE MARKET
ANALYTICAL METHOD FOR DESIGN OF FIRE RESISTANCE OF STEEL STRUCTURAL ELEMENTS
Full text linkThe engineering approach in the design of fire prevention allows the engineer to study fire pre-vention solutions that do not meet the requirements of the Rules provided that they ensure the same level of fire safety.
To design interventions appropriate to ensure the fire resistance of structures, and in particular for the steel structures, the performance approach of the Rules requires the adoption of prede-fined solutions as a function only of the structural material and the required fire resistance.
The performance approach of the Norms, therefore, does not take into account the loads acting on the structural element and the critical temperature, which is the temperature at which the load that can be worn in hot equals the exercise load.
Often, during the design phase, some of the requirements of rules are difficult, if not impossible to meet. A practical example is that of a restoration project of a historic building, for which interventions are required non-invasive, reversible and compatible.
In this paper it is presented a study that enables you to design interventions appropriate to en-sure the fire resistance of structural elements with an analytical method and, therefore, with an engineering approach. In particular, according to the fire scenario adopted, the analytical method proposed allows to determine the critical temperature of the structural element under study, depending on the working load, the resistant section and solicitation of project.
Subsequently, depending on the critical temperature and the required fire resistance, it is possible to design the appropriate fire-fighting interventions
Durabilità del cemento armato e le classi di esposizione ambientale.
No full textLe cause di aggressione dovute all’ambiente possono essere formalmente suddivise in chimiche, fisiche, meccaniche e biologiche (tabella 4.1). In realtà, difficilmente in un processo di degradazione esiste un solo fenomeno aggressivo, spesso sono più cause che concorrono al deterioramento del materiale; tuttavia però esiste sempre quella che può essere definita la causa fondamentale che innesca il processo degradante.
Per garantire la durabilità delle strutture in calcestruzzo armato ordinario o precompresso, esposte all’azione dell’ambiente, si devono adottare i provvedimenti atti a limitare gli effetti di degrado indotti dall’attacco chimico, fisico e derivante dalla corrosione delle armature e dai cicli di gelo e disgelo, in relazione alla norma europea UNI-EN 206-1. In accordo con la norma UNI-EN 206-1 e con quella italiana UNI 11104 il livello di rischio per una determinata opera dipende dall’ambiente cui la stessa è esposta.
The causes of aggression due to the environment can be formally divided into chemical, physical, mechanical and biological (table 4.1). In reality, in a degradation process there is hardly a single aggressive phenomenon, often there are several causes that contribute to the deterioration of the material; however, there is always what can be defined as the fundamental cause that triggers the degrading process.
To ensure the durability of ordinary or pre-stressed reinforced concrete structures exposed to the action of the environment, measures must be taken to limit the effects of degradation induced by chemical and physical attack and resulting from the corrosion of the reinforcements and cycles of freeze and thaw, in relation to the European standard UNI-EN 206-1. In accordance with the UNI-EN 206-1 standard and the Italian UNI 11104 standard, the level of risk for a given work depends on the environment to which it is exposed

Castel Sant’Elmo a Napoli: da simbolo del potere a centro di cultura
No full textIl sito di Castel Sant’Elmo a Napoli ha sempre rappresentato, per la posizione strategica, affacciata alla città dagli spalti della collina di San Martino, un simbolo forte del potere. Durante il ventennio fascista l’architetto napoletano Camillo Guerra, in collaborazione con gli ingegneri Ferretti e Gianturco, rimarcava il valore simbolico del luogo con il progetto di una torre littoria da erigersi al centro del cortile interno del castello, a irradiare con la propria presenza “la luce del Littorio” sulla città (di tale progetto è possibile ricostruire la storia, in relazione a materiali e tecniche dalle carte dell’Archivio Guerra, conservato presso il Dipartimento di Ingegneria Edile dell’Università degli Studi di Napoli Federico II). A seguito dei restauri avviati nel 1976, la struttura ha assunto una connotazione culturale per l’ospitare alcuni uffici della Soprintendenza. Il luogo, la storia, la memoria indicano, pur tuttavia, una valenza che va oltre l’attuale utilizzo: Castel Sant’Elmo come centro di cultura, sede del nucleo vitale di una struttura inter-bibliotecaria cittadina. | The site of Castel Sant'Elmo in Naples has always been, due to its strategic location overlooking the city from the ramparts of the hill of San Martino, a strong symbol of power. During the Fascist period, the Neapolitan architect Camillo Guerra, in collaboration with the engineers Ferretti and Gianturco, emphasized the symbolic value of the location with the design of a Fascist tower to be erected in the center of the inner courtyard of the castle, so as to radiate with its presence "the light of Fascism" over the city. (It is possible to reconstruct the history of this project, in relation to materials and techniques, from the documents of the War Archive, preserved in the Department of Civil Engineering, University of Naples Federico II.) Following restoration work begun in 1976, this structure has gained cultural connotations for the fact that it hosts some of the offices of the Superintendency for the Artistic and Historic Heritage of Naples. Its location, history, and memory indicate, nonetheless, a value that goes beyond its current use: Castel Sant'Elmo as a cultural center, home to the vital core of a municipal library system
THE HOLY MONUMENT ANNUNZIATA IN CAVA DE’ TIRRENI (SA) HISTORICAL ANALYSIS OF THE BUILDING FOR A PROPOSAL OF A RELIGIOUS HOUSE OF HOSPITALITY
Full text linkIn this paper it is presented a research for the enhancement, the reuse and the
architectural recovery of the holy monument Annunziata, located in Cava de 'Tirreni (SA).
The Annunziata resort is one of the oldest farmhouses: it’s located on the south-eastern
slope of Mount Castello and it’s a destination for tourists and pilgrims from all over Italy
who visit the "Little Lourdes", that is a faithful reproduction of the famous French cave.
The large architectural complex, dating to 1506, is characterized by multiple layering,
alterations and extensions and it includes the church of the Annunziata with its pertaining
premises, the sacristy, the bell tower, the baroque St. Andrea’s chapel and the imposing
structure of the former monastery with various venues, the cloister, the oratory, the
pertaining spaces open. Due to its architectural value and the amplitude of its built-up
volumes, it has an important urban role in the context.
Starting from a thorough historical analysis of the monument and analyzing the
technological and constructive systems used, it is expected to intervene by first defining a
restoration project aimed at enhancing in particular the interior environments, the
structural elements and finishes of the church and its pertaining premises, in full respect
of the constraints of the Superintendence for the Cultural Heritage and Activities of the
Campania Region, to which the building organization is subject.
A second intervention is then aimed at the retraining and reuse of the former monastery,
including the cloister, the oratory, the perpetual areas and the open spaces, attributing
the building to a new destination, that is compatible with both the typological features
originated and the capacity of the structural elements, in full respect of architectural
constraints
NAPLES TO UNVEIL. A WIDESPREAD MUSEUM: THE ROAD CURTAINS OF THE THREE DECUMANI
No full textThe Neapolitan historic centre, for his multiple historic and artistic testimonies, can be considered a real “outdoor Museum” of the city. From the itself bird’s eye view you can admire the rich structure of squares, streets, alleys, extraordinary monuments, aristocratic palaces, decent buildings and simple constructions placed into specific urban grids. Different realities that you can recognise everywhere by observing the relations with the urban context extended to more and less large morphological areas, or by going to their historic matrices which have generated them and reading their connotations in successive periods of time, or, also, by analysing the constructive and compositional aspects of the building units, introducing an open classification to explore their form, structure, deterioration, etc.
Walking through the Major, Superior and Inferior Decumani, which have already been favourite locations for ancient Greeks and Romans, you can admire the prestigious facades of fifteenth and sixteenth century Palaces of Neapolitan noble families like Carafa, Filomarino, Mazziotti, Pignatelli, Marigliano. Prospectuses that become the privileged place of the evident expression of a demonstration of the noble local power, through which great figures of architects show modern techno-structural capabilities, anticipating, sometimes, ideas and modus operandi that will become more typical for the Roman, Raphaelesque and Michelangelesque Renaissance. Masonry palaces with the characteristic yellow and grey tuff, morphologically developed around a central court which is accessed by an elegant vaulted vestibule, characterised by the rigorous ashlar facies, in opus isodomum, in a style aimed at recovering a classic formal language made by emblems, shields, statues, capitals, volute, reveal a rich and innovative city. The prospectuses of the sumptuous palaces of the Parthenopean Decumani become a stimulating page to read and understand for the knowledge of the city’s historical identity, to extract data from it, in a priceless experience which offers an immediate fruition to the pleased gaze
