Data parametric representation for monitoring of cultural heritage
No full textThe present paper analyses the Abbey of S. Matteo in Genoa exemplifying a possible use of survey and its elaborations in the field of conservation. The three-dimensional survey was used as the basis for the collection, management and representation of the data derived from the survey on rising damp. The purpose was to test a dynamic data processing system that could be used as a tool to collect data on site as well as to access data remotely. By using software for three-dimensional representation and a node programming language, it was possible to define a system that offered dynamic viewing and was easy to use, through the use of chromatic scales and level curves, which can be generated starting from tables containing numerical data. Surveying, diagnostics, modelling and representation allow one to experiment with new ways of interaction within the common goal of conservation
A Journey of Valorisation from the Sacred to the Secular. The Oratory of Sant’Antonio Abate in the Village of Mele (Genoa-Italy)
No full textThe Oratory was the expression of a community that, even with its strong sense of identity and wealth (deriving from the profitable local paper mills and ironworks), felt the need for a symbol, which could represent them; a morally enlightening space, spiritually transcendent, and socially prestigious. The development and the creation of the project allowed professionals in the fields of Restoration, Drawing, and Informatics to work together but mainly it created the opportunity to become acquainted with an ancient collective devotional culture, which has an undeniably fundamental value from an historical and anthropological point of view. The goal was to develop a mobile application which does not incorporate the use of 3D models, but was easily accessible by the visitor. Inside the app, information sheets and images of detail offer a more thorough understanding of Oratory, also thanks to using special sensors (Beacon) and graphic symbols (QRcode)
A Geotechnical Analysis to Assess the Effect of Slow-Moving Landslides on Historic Masonry Churches
No full textThe protection of cultural heritage from water-soil interaction related threats is a crucial challenge for the scientific community. Among the hazards threatening heritage buildings, slow-moving landslides have been recently found to produce significant damage to historic masonry churches. However, assessing the effects of these phenomena is very challenging, as detailed information about slow-moving landslide movements is not generally available. To tackle this problem, geotechnical analyses can be performed, which enable the landslide-induced soil displacement profiles to be predicted. In view of this, this paper investigates the effects of slow-moving landslides on historic masonry churches by performing geotechnical analyses on two case studies located in the Liguria region (Italy). For each case study, limit equilibrium (LE) and finite element (FE) analyses were carried out with reference to representative sections of the slope on which the building was located. Different scenarios of water table levels were also simulated to evaluate a potential evolution of the slope stability conditions towards failure. Finally, the damage level of the building under study was assessed through a damage criterion available in the literature and compared with the severity of the damage observed on site
Damage Assessment of Historic Masonry Churches Exposed to Slow-moving Landslides
No full textThis paper presents a first contribution to the damage assessment of historic masonry churches exposed to slow-moving landslides. No studies have ever been devoted to systematically investigating the effects of slow-moving landslides on this type of structures. In this work, a damage survey campaign was performed on 33 listed churches located in landslides-affected areas in the Liguria region (Italy). For each church, information regarding zoning, state of activity and estimate direction of landslide phenomena was collected and analysed. A suitable knowledge of the main geometric and structural features as well as of history and past interventions was achieved for each building by means of on-site surveys and archival research. A detailed field-survey of crack patterns and deformations was also performed. The critical assessment of the damage observed allowed to put forward some original remarks on the structural response of historic masonry churches to slow-moving landslides. Furthermore, some recurrent types of damage and damage mechanisms were identified for the first time
A Simplified Procedure for the Out-of-Plane Seismic Assessment of Free-Standing URM Elements: Application to the Abandoned Ancient Village of Bussana (Sanremo, Imperia - Italy)
No full textThis paper addresses the safety of connections within urban areas, where free-standing elements that menacingly overlook them are susceptible to potential overturning mechanisms. Such a condition recurs in post-earthquake scenarios and in historical centers abandoned after disasters in seismic-prone areas, which aimed to be restored to create safe pathways for tourists. The paper presents a simplified procedure for the out-of-plane seismic risk assessment of free-standing unreinforced masonry (URM) elements in historical centers. The procedure can be applied to several URM free-standing elements, such as artistic pieces or nonstructural components, but also rocking panels resulting from the collapse of structures in post-event damage scenarios. The procedure is based on the definition of hazard, exposure, and vulnerability, which are combined to assign a risk class to each element and define a priority of intervention. The procedure relies on the kinematic approach but requires a limited number of parameters to be feasible when applied to many elements. Some of them can also be acquired through innovative survey techniques, like unmanned aerial vehicle photogrammetry. To demonstrate its utility, the procedure is applied to the abandoned village of Bussana (Sanremo, Imperia - Italy), severely hit by the 1887 earthquake and partially reoccupied in the 1960s
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
Historic masonry churches exposed to slow-moving landslides: A critical damage assessment
No full textThis paper deals with the damage assessment of historic masonry churches exposed to slow-moving landslides. A damage survey campaign was carried out on 33 listed churches located in the Liguria region (Italy) in areas affected by slow-moving landslides. For each church, information about zoning, state of activity and direction of landslide phenomena was collected and analyzed. Knowledge of each building’s main geometric and structural features, history and past interventions was gained by means on-site surveys and archival research. A detailed field-survey of crack patterns and deformations was also performed. Based on the critical assessment of the damage observed, preliminary conclusions on the structural response of historic masonry churches to slow-moving landslides were made. Recurrent types of damage and damage mechanisms were also identified
