Seismic assessment of complex historical buildings: application to Reggio Emilia cathedral, Italy
No full textStructural monitoring of damaged cultural heritage buildings after the April 2009 Abruzzo earthquake
No full textThe 6th of April 2009 a major earthquake struck the central part of Italy, causing hundreds of casualties and devastating the historical city of L’Aquila and several small towns in the area. The toll in terms of structural damage was enormous, also considered that a vast amount of buildings was made of poorly arranged masonry composed by round pebbles, with mortar of scarce mechanical characteristics. In particular, the buildings belonging to cultural heritage were between the structures that suffered more from seismic damage.
The first step in the process of reconstruction was to provide the minimum safety conditions to the structures, in order both to avoid the damage progression and to allow to proceed with the necessary successive strengthening or retrofitting intervention with adequate safety conditions.
In this framework, structural monitoring was employed in emblematic buildings to control the damage progression or stationariness with reference to the already carried out stabilisation interventions, or to allow a safer workplace during the execution of the interventions, also evaluating the effectiveness of the used strengthening techniques.
The paper presents the first results of two dynamic and static monitoring systems, installed in the St. Mark church – a heavily damaged church of the city centre, and in the Spanish Fortress (L'Aquila castle), installed after a first experimental investigation campaign carried out in September 2009
Consumption of the Performing Arts from a Supply-Side Perspective: Searching for the Artistic Benefit
No full textThis paper focuses on the artistic benefit for the audience in arts and culture consumption. This benefit is defined as the feeling of being part of the artistic process and it is generated by participatory dynamics and value co-creation. The artistic benefit interacts with other benefits (functional, symbolic, emotional, social) that are involved in the performing arts experience. Its analysis, from a supply-side view, could help to advance arts and culture marketing into a servicedominant logic. An empirical study involving two phases has been designed. First, a qualitative, explorative and item-generation investigation was carried out. A quantitative study was then undertaken to streamline the item-generation process and evaluate the validity of the identified semantic dimensions. The analysis identified the artistic benefit as composed by three different factor that we labelled: breaking, participatory and dialogic. The results confirm the relevance of the topic as a means of shedding light on the audience experience in arts consumption
eWOM and growth strategies for the tourism industry in maritime museum networks. The case of the ARCA Adriatica tourist product
Full text linkMuseum networks are proliferating in the Mediterranean area showing new forms of collaboration between public and private institutions. Museums and heritage conservation play a fundamental role in tourism development. The purpose of the present working paper is to provide an analysis of the museum network experience in order to define a set of useful and viable marketing strategies to be adopted by the museum management with respect to the relative tourist context. The case of the Arca Adriatica maritime museum network - a network of eight maritime museums representing the core asset of an elaborated tourist product - has been analyzed and considered particularly relevant and of peculiar interest. After the analysis of the museum network and its most important related points of interest, managerial recommendations within strategic and tactical perspectives are hence presented

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
SHM for historical buildings: preventive and post-earthquake controls
No full textStructural health monitoring (SHM) is being more and more applied in the study of cultural heritage (CH) buildings, as a key activity to increase the knowledge on their structural behavior and to have a deeper insight on their conditions. This knowledge allows to carry out with more confidence (and only if necessary) possible strengthening interventions, but also to prevent the execution of intrusive repair works, if they are not justified by an experimentally demonstrated worsening of the structural conditions. The use of monitoring systems applied under ordinary conditions and installed on CH structures allows to: (i) validate the functioning of the adopted structural models; (ii) identify the ongoing damaging processes; (iii) validate the effectiveness of the strengthening interventions. In case of a seismic event, SHM can furthermore prove its usefulness in order (i) to quantitatively evaluate the progression of the assessed damage pattern, (ii) to design effective and urgent interventions if an unsafe displacement patterns is recorded, (iii) to define an early warning procedure for the safety of the workers employed in the strengthening interventions. Monitoring can also be effective when implemented on seriously damaged buildings, if the time schedule for the interventions is difficult to be a priori planned. In this framework, the authors (University of Padova, Italy) in collaboration with the officer of the Cultural Heritage Authority, the university of Nagoya (Japan), the National Institute of the Conservation and Restoration (ISCR) designed and installed SHM systems on six representative and emblematic CH buildings in L’Aquila after the devastating earthquake occurred on the 6th of April 2009 in the Abruzzi Region. The selected case studies SHM systems – presented in the paper – will allow to confirm the effectiveness of the use of structural monitoring during and after the emergency activities in case of a seismic event
Comparative Evaluation of Investigation Testing Methods in Timber Elements considering Moisture Content
Full text linkWood components in existing buildings suffer from deterioration and damage due to environmental conditions and loading effects. Their preservation strongly depends on the knowledge level of their onsite condition supported by the application of low-intrusive methods of investigation. Estimating the mechanical performance of wood in constructions cannot disregard the evaluation of moisture content. In this paper, 31 wood elements (19 recovered from disassembled buildings and 12 new) underwent a series of non-destructive tests (i.e., ultrasonic and sonic stress wave methods) and semi-destructive tests (i.e., resistance drilling and pin penetration). Red/white firs and pine species constituted the recovered elements; red fir and larch the new ones. The effect of moisture content on the results of low-intrusive methods was estimated by either electric or electromagnetic devices. Destructive tests (in bending and compression) were also carried out on 10 recovered and six new elements, and results were correlated with those of semi-destructive tests
Codes of practice for architectural heritage in seismic zones
No full textThe acknowledgment from the scientific community that the buildings belonging to the cultural heritage can not be evaluated with regards to the seismic action according to standards that are fitted for newly constructed buildings, indicated a new way to undertake in the seismic assessment of such class of buildings. In particular, it was accepted that the balance between structural safety and architectural preservation must take into account both exigencies, on one hand not fully complying with the seismic actions defined by the standards if this would lead to interventions that can alter in a significant manner the cultural and architectonical essence of the building, on the other even changing the use of a specific building, in order to make it able to withstand the seismic action. Safety evaluations must then involve a multidisciplinary, qualitative/quantitative approach
