Gli edifici del periodo razionalista in Italia: modello per la valutazione della vulnerabilità sismica
Full text linkThe seismic vulnerability that characterizes the architectural heritage in Italy requires methods applicable at territorial scale, simplified but reliable for a proper risk assessment and a subsequent planning of intervention strategies. For this purpose, in the present work a method for the seismic vulnerability evaluation at territorial scale was developed in order to analyze the buildings built in Italy between 1930 and 1940, belonging to the architectural movement of Italian Rationalism. Starting from the vulnerability method, based on the European Macroseismic Scale (Grunthal, 1998; Giovinazzi and Lagomarsino, 2004), the proposed methodology provides new parameters related to specific vulnerabilities of the Rationalist architectural heritage. The analysis of these buildings, represented by a sample geographically contextualized to Liguria region (Italy), pointed out that the vulnerability is related to two main reasons. The first reason is the formal characteristics, related to the research of lightness, transparency and boldness that characterized the new architectural language which, in those years, was developing in Italy, as in the rest of Europe. At the base of the formal choices is the use of reinforced concrete, a "new" construction technology: if the use of this material was a valuable tool for the formal renovation in architecture, it is true that it is, at the same time, the second cause of the vulnerability that characterizes the buildings belonging to the Italian Rationalism. In fact, it is necessary to take into account that the construction technique was in its "first steps" at the beginning of the last century, and that, therefore, had not yet fully mastered, causing structural problems, in some cases, already from a static point of view. The scores of vulnerability, assigned to the parameters identified, have been calibrated through parametrical sensitivity analysis on a building "prototype", from a real case study, selected as representative of certain recurring characteristics in the sample. The proposed method allows to assess the vulnerability of this cultural heritage, that is higher than the vulnerability that characterized the reinforced concrete existing building with modern design

The Historical Buildings of Minori: A Preliminary Assessment for the Restoration of a Unesco Site
No full textThe registration of the Amalfi Coast in the UNESCO World Heritage List has highlighted the need to rethink the preservation strategies adopted for the architectural features of its 15 municipalities. Their historical buildings are subjected to intensive touristic exploitation and inadequate interventions for urban development and mitigation of the hydrogeological risks posed by land degradation. Minori is one of such municipalities, rich of valuable structural and environmental assets. The field study conducted on the historical masonry has made possible the development of guidelines for restorative interventions coherent with the architectural peculiarities of Minori. The examinations have been conducted in an holistic perspective, by analysing diachronic features such as buildings evolution and spatial relations over time, construction techniques and materials employed. The aim of the study is highlight the cultural relevance of the hystorical masonry in Minori, its relationship with the coastal environ- ment, and its link with the local social identity
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
