New insights to assess the consolidation of stone materials used in built heritage: the case study of ancient graffiti (Tituli Picti) in the archaeological site of Pompeii

New Alpine companies, like Crans-Montana on the Haut-Plateau, remain, more often than not, trapped in representative logic opposing the clan of modernists to that of defenders of values anchored in an ideal-typical tradition. The Haut-Plateau territory, so named due to its geographic location and topographic conformation – not for the morphology of the soil – was still a space free of any construction in the mid-nineteenth century. This vast alpine meadow was marked by a few utility buildings for sheltering cattle and hay during the intermediate seasons that precede the full summer. At the turn of the 3rd millennium, the built heritage, essentially consisting of hotel structures and holiday residences, is no longer able to welcome the new socio-economic dynamics linked to the mono-culture of skiing. This crisis calls habits, both old and new, into question, given the youth of the tourist resort. In June 2000, a Federal programme selected Crans-Montana as a case study for testing an Environment and Health Action Plan. This provided an opportunity for a group of architects to formulate an inter-municipal blueprint that activated a series of urban renewal projects. The new architectural formulae that emerge try to go beyond stylistic modernism by reinterpreting the relationship with the built environment and its social context.

AbstractToday, the concept of built heritage authenticity is a projection screen for conflicting demands and thus a ‘contested field’. Short-sighted readings started to drag the concept behind different ill-considered treatises, in which some heritage aspects loosely outweighed other aspects. Archaeological perspectives that tend to freeze heritage structures in time, such as those that are privileged upon other contemporary socio-cultural issues, while political takes also overshadowed other epistemological prospects, and vice versa. Repercussions have made inclusion of what is regarded as ‘inevitable changes’ within the built context problematic as to the re-interpretation and thus assessment of its authenticity. Despite their possible momentary threat to the latter, these changes may add to the cultural value of the context over time, granting new potential that may instead boost its authenticity. This paper investigates the potential continuity of Erbil Citadel’s Babylonian Gate as an inevitable change within the site’s built context by studying the Gate’s controversial political impacts on the context’s authenticity. This study affirms that authenticity is a transcendental value of an open-ended progressive nature, which cannot be reduced to a specific period or properties within the historical chronology of built heritage. Hence, authenticity should be approached as a meaningful existential issue, while revelation of its essence and thus its dimension entails precise scrutiny of both the tangibles and intangibles of the context. However, to be part of its authenticity, any change in the context should be adaptable and possibly incorporated as a new value within its cultural strata, thus enabling progressive support for site authenticity.

Unmanned aerial vehicles are currently the most used solution for cultural heritage in the field of close range and low altitude acquisitions. This work shows data acquired by multitemporal and multispectral aerial surveys in the archaeological site of San Vincenzo al Volturno (Molise, Italy). The site is one of the most important medieval archaeological sites in the world. It is a monastic settlement that was particularly rich during the early Middle Ages, and is famous for its two full-frescoed crypts which represent a milestone in the history of medieval art. Thanks to the use of multispectral aerial photography at different times of the year, an area not accessible to archaeological excavation has been investigated. To avoid redundancy of information and reduce the number of data to be analysed, a method based on spectral and radiometric enhancement techniques combined with a selective principal component analysis was used for the identification of useful information. The combination of already published archaeological data and new remote sensing discoveries, has allowed to better define the situation of the abbey during the building phases of the 8th/9th century and 11th century, confirming and adding new data to the assumptions made by archaeologists.

Seismic Response Of Buildings

Infilled reinforced concrete (IRC) frames are a very common construction typology, not only in developing countries such as Pakistan but also in southern Europe and Western countries, due to their ease of construction and less technical skills required for the construction. Their performance during past earthquakes has been in some cases satisfactory and in other cases inadequate. Significant effort has been made among researchers to improve such performance, but few have highlighted the influence of construction materials used in the infill walls. In some building codes, infills are still considered as non-structural elements, both in the design of new buildings and, sometimes, in the assessment of existing buildings. This is mainly due to some difficulties in modeling their mechanical behavior and also the large variety of typologies, which are difficult to categorize. Some building codes, for example, Eurocode, already address the influence of infill walls in design, but there is still a lack of homogeneity among different codes. For example, the Pakistan building code (PBC) does not address infills, despite being a common construction technique in the country. Past earthquake survey records show that construction materials and infill types significantly affect the seismic response of buildings, thus highlighting the importance of investigating such parameters. This is the object of this work, where a numerical model for infill walls is introduced, which aims at predicting their failure mode, as a function of some essential parameters, such as the friction coefficient between mortar and brick surface and mortar strength, usually disregarded in previous models. A comprehensive case study is presented of a three-story IRC frame located in the city of Mirpur, Pakistan, hit by an earthquake of magnitude 5.9 on 24 September 2019. The results obtained from the numerical model show good agreement with the damage patterns observed in situ, thus highlighting the importance of correctly modeling the infill walls when seismically designing or assessing Pakistani buildings that make use of this technology.

The Impact

In recent years, the impact of Climate change, anthropogenic and natural hazards (such as earthquakes, landslides, floods, tsunamis, fires) has dramatically increased and adversely affected modern and past human buildings including outstanding cultural properties and UNESCO heritage sites. Research about protection/monitoring of cultural heritage is crucial to preserve our cultural properties and (with them also) our history and identity. This paper is focused on the use of the open-source Google Earth Engine tool herein used to analyze flood and fire events which affected the area of Metaponto (southern Italy), near the homonymous Greek-Roman archaeological site. The use of the Google Earth Engine has allowed the supervised and unsupervised classification of areas affected by flooding (2013–2020) and fire (2017) in the past years, obtaining remarkable results and useful information for setting up strategies to mitigate damage and support the preservation of areas and landscape rich in cultural and natural heritage.

The objective of this paper is to apply the life cycle assessment methodology to assess the environmental impacts of light steel framed buildings fabricated from cold formed steel (CFS) sections. The assessment covers all phases over the life span of the building from material production, construction, use, and the end of building life, in addition to loads and benefits from reuse/recycling after building disposal. The life cycle inventory and environmental impact indicators are estimated using the Athena Impact Estimator for Buildings. The input data related to the building materials used are extracted from a building information model of the building while the operating energy in the use phase is calculated using an energy simulation software. The Athena Impact Estimator calculates the following mid-point environmental measures: global warming potential (GWP), acidification potential, human health potential, ozone depletion potential, smog potential, eutrophication potential, primary and non-renewable energy (PE) consumption, and fossil fuel consumption. The LCA assessment was applied to a case study of a university building. Results of the case study related to GWP and PE were as follows. The building foundations were responsible for 29% of the embodied GWP and 20% of the embodied PE, while the CFS skeleton was responsible for 30% of the embodied GWP and 49% of the embodied PE. The production stage was responsible for 90% of the embodied GWP and embodied PE. When benefits associated with recycling/reuse were included in the analysis according to Module D of EN 15978, the embodied GWP was reduced by 15.4% while the embodied PE was reduced by 6.22%. Compared with conventional construction systems, the CFS framing systems had much lower embodied GWP and PE.

AbstrakKelantan terletak dalam pengasingan dari koridor perindustrian di pantai barat dan jauh dari pengaruh KualaLumpur, Pulau Pinang dan Singapura. Adalah penting untuk menentukan daya-daya penentu pertumbuhanbandar di negeri ini kerana pusat-pusat bandar di Kelantan mempunyai gabungan unik antara potensidan kekangan. Walau bagaimanapun, sebagaimana proses globalisasi dan urbanisasi perbandaranyang berlaku di seluruh dunia, evolusi senibina di Kelantan tidak terkecuali dan pemeliharaan nilai-nilaisejarah yang unik perlu dilakukan. Warisan senibina Kelantan hari ini kurang dihargai oleh masyarakatkerana karaktornya yang terpencil dan kurang baik. Hal ini kerana proses pengekalan bangunan warisankurang diberi perhatian dan juga kurang mendapat penekanan daripada pihak berkuasa dan masyarakatsendiri. Terdapat banyak bangunan-bangunan bersejarah di Kota Bharu yang telah dirobohkan untuktujuan pembangunan bandar dan ada sebahagian bangunan diberi pengaruh gaya seni bina modendan kontemporari tanpa mengambil kira nilai sejarah yang sedia ada. Pertumbuhan intervensi senibinaadalah tidak dapat dielakkan atas permintaan untuk memenuhi keperluan perbandaran. Akibatnya, corakpersekitaran bandar dan warisan senibina ini mengalami perubahan sepanjang proses pembandaran.Selain itu, perubahan telah memberi kesan kepada suasana persekitaran iaitu bangunan (warisan alambina), serta perancangan jalan dan aktiviti. Abstract Kelantan is situated somewhat in isolation from the industrial corridor of the west coast and far from thesphere of influence of Kuala Lumpur, Penang and Singapore. It is important to determine the forces of thestate’s urban growth determinants because urban centers in Kelantan have their unique mix of potentialsand constraints. However, as far as globalization and urbanization that are taking place worldwide, thearchitectural evolution in Kelantan is not exempted and the preservation of any unique historical valueshould be done. The heritage architecture value of Kelantan today, has not been appreciated by localfolks and society because of its isolated and poor characters which has not been maintained and wellemphasized by the authority and society themselves. Hence, the remarkable heritage property has been‘invisible’ and demolished due to negligence and time factors. Moreover, there are many historical buildingsin Kota Bharu that had been demolished for urban development purposes and the influence of modernand contemporary architecture style without considering the existing and distinctive of historical value.The growth of architectural intervention is inevitably due to society and its demands to fulfill their urbanneeds nowadays. As a result, the pattern of urban setting and heritage property had changed throughoutthe years of urbanization. Moreover, the changes have affected the ambiance of surrounding i.e. buildings(built-heritage), and streets planning and activities.
