Saperi di base. Grammatica e retorica fra i codici di Niccolò Cusano
No full textIl saggio analizza le tradizioni retoriche e grammaticali presenti nella collezione libraria di Nicola Cusano, con particolare attenzione per il fondo di Bernkastel-Kues. Importanti le novità che emergono circa le modalità di utilizzo di questi testi da parte del dotto prelato tedesco, la tipologia delle opere e degli autori conservati (che abbracciano tradizioni tardo antiche, medievali e umanistiche), e la funzione che esse avevano nella raccolta. Di particolare rilievo le considerazioni circa il "vetustissimus" esemplare delle "Controversiae" di Seneca Retore (Bruxelles, BR, 9581-9595), e quelle relative all'esemplare della pseudo aristotelica "Rhetorica ad Alexandrum regem" nella traduzione di Francesco Filelfo (Bernkastel-Kues, St. Nikolaus Hospital, 180), sul quale vengono qui per la prima volta individuati marginali autografi latini di Nicola Cusano e greci di Francesco Filelfo

A limit analysis approach for masonry domes: the basilica of San Francesco di Paola in Naples
No full textThe object of the present study is the basilica of San Francesco di Paola, an historical structure that well lends itself to use the graphic method of statics to analyse its stability for a two-fold reason: on the one hand, it is an interesting structure being dominated by a dome of considerable size with a solid appearance, and on the other, it is an entirely masonry structure for which no consolidation interventions with different materials have been necessary so far. This paper applies limit analysis based on the geometric equilibrium of the dome starting from detailed surveys of the church, from the knowledge of its history construction to the comprehension of the entire building. The study carried out enriches previous researches developed around the same case study, and the new contribution is integrated by the analysis of stability of the buttress system that completes the work on the vertical loads, providing a more detailed assessment of the safety level of the structure

A STUDY ON FORM AND SEISMIC VULNERABILITY OF THE DOME OF SAN FRANCESCO DI PAOLA IN NAPLES
No full textThe aim of this research is the structural study of the hemispherical dome of San Francesco di Paola in Naples and, in particular, the evaluation of its degree of seismic safety not considering the role of the supporting structures. The methods we adopt are based on the determination of a class of purely compressive stress regimes, which are balanced with the load. Within the unilateral model for masonry (Heyman 's model), the mere existence of such a class is a proof that the structure is safe; members of this class can be used to assess the geometric degree of safety of the structure and to estimate bounds on the thrust forces exerted by the structure on its boundary. The analysis has been performed, by using both the graphical method and the membrane approach. The methodological innovation consists in the use of both the analytical and the traditional methods of graphical calculation of masonry structures, considering both vertical and horizontal loads. As a result of our analysis, we conclude that the sole dome can sustain a horizontal load of 0,577 g
On the statics of large domes: A static and kinematic approach for San Francesco di Paola in Naples
No full textThe aim of this paper is to establish a general methodology of approach to assess the safety of the architectural heritage. Starting to a "case study", the problem of the behavior analysis of masonry buildings has been developed on the basis of some simple hypotheses about the material and on the basis of theoretical concepts. The Elastic Theory, used to check modern structures, is not suitable for masonry, material much more heterogeneous and complex. As demonstrated by the ancient builders, the most appropriate theory to study historical constructions is the Limit Analysis [1]: a better understanding of the mechanics for these structures is needed, since it is not the stress the most important parameter for masonry, but it is the stability [2]. The case approached deals with the dome of the Basilica of San Francesco di Paola in Naples, designed and built by the Swiss architect Pietro Bianchi in the nineteenth century, for the royal will of Ferdinand IV of Bourbon [3,4]. In order to assess this structure, the limit analysis approaches are here compared and, on the basis of classical limit analysis, local mechanisms are considered. A static (safe theorem) and a kinematic approach are applied to the structure by means of equilibrium limit conditions and kinematically admissible collapse mechanisms. © 2018 The International Masonry Society (IMS)
The neoclassical dome of san francesco di Paola in Naples. A study on form and stability. (Aimeta 2017)
No full textThe Basilica of San Francesco di Paola, located at the west side of Piazza del Plebiscito, historic center of Naples, was built as a completion of the square in front of the Royal Palace by the will of King Ferdinand IV (1816), designed by the Swiss architect Pietro Bianchi. The "The Bourbon Temple" is mainly characterized by its imposing coverage with hemispherical dome, which protrudes from the complex. It directly refers to the Pantheon for its geometric relations and proportions, its formal and compositive aspects, although it is not completely hemispherical and its interior does not enjoy the spatiality of its model. Furthermore in origin the dome ended with a central oculus in which, even today, the structural forces converge and balance. Subsequently, a lantern was placed on the oculus, which is a conical element completely in glass that allows the passage of light. The aim of this work is the study of the stability of the dome that, firstly, allows to specify the overall safety of the structure in its current state, especially with regard to statics. Secondly, to assess the degree of seismic safety of the structure, identifying the potential conditions of vulnerability in case of earthquake. The static analysis has been performed, by using the graphical method, according with the principles of the limit analysis applied by Heyman to the masonry structures. The methodological innovation consists in the use of the traditional methods of graphical calculation of masonry structures, interconnected with the new antiseismic norms in the territory. The operational aspect of the work is contained in the interdisciplinarity of scientific fields, with the aim of obtaining a complete knowledge of the monument in its current condition without using an elastic analysis, which would not be suitable for the study of historical building
THE DOME OF THE SAN FRANCESCO DI PAOLA BASIL: A REAL GEOMETRY BASED ASSESSMENT
No full textThis study presents an assessment of the state of stress of the dome of San Francesco di Paola Basil Naples. The number of Finite Analyses of masonry structures proposed over the years is now uncountable, but most of the studies make reference to ideal geometries, even if based on actual measurements. The present work, on the contrary, does not rely upon any regular geometrical model but, instead, on what could be defined as a scan of the actual structure which accounts for both the original plan and on the inevitable construc�on imperfec�ons.
It is found that these apparently negligible, but diffuse imperfec�on from an ideal modelling lead to a substan�ally different state of stress from what could be expected from a regular geometry. The findings are discussed and it is also shown that they give reason of the actual cracking paterns on the dome
