“…In general, the process is very complex and aims at assessing any type of variation that may influence the structural performance of an infrastructure and is attributable to changes in materials, geometric properties, boundary conditions, and constraint configurations. In summary, the assessment of the damage [32], where the damage is intended as any change that, introduced into the system, may negatively affect its current and future performance.…”

Architectural heritage is perhaps the most important marker of the Italian and European landscapes. Over the last decades, its strategic relevance for local economic development has led to prioritize tourism-oriented promotion objectives. Therefore, new light has been thrown on once unknown resources that have thus received the attention of tourists interested in new visit experiences. To this end, Information and Communication Technologies (ICTs) have delivered a crucial support mainly in terms of public attraction and creation of new cultural offers. However, new urgent challenges now face tangible heritage, whose physical existence is jeopardized through extreme events and poor maintenance. Unexpected intense visit flows represent in themselves a further threat for sensitive heritages. ICTs have then to cope with more complex conservation tasks and the Internet of Things (IoT) can facilitate appropriate solutions. The paper presents a smart sensor-based infrastructure for the structural monitoring of S. Domenico Church in Matera, an emblematic city for the concerns described, which also highlighted the need for a wider conservation concept also embracing context and fruition issues. The article introduces the case study and its delicate environment, and the technological background of heritage monitoring solutions; the proposed IoT infrastructure is then described, discussing its potentialities and IoT contribution to creating more holistic and multiscale perspectives to heritage conservation.

“…The AVT method is commonly used for heritage structures as it requires no excitations, although it involves significantly more post-processing effort than FVT for estimating the uncertain structural parameters [20,21]. Non-destructive tests using ambient vibrations have been employed for dynamic structural identification of multi-leaf masonry walls that have intrinsic structural complexity, heterogeneity, and irregularity [22].…”

Dynamic Characterisation of a Heritage Structure with Limited Accessibility Using Ambient Vibrations

Historic Cairo has been a UNESCO World Heritage Site since 1979. It has more than 600 historic structures, which require extensive studies to sustain their cultural, religious, and economic values. The main aim of this paper is to undertake dynamic investigation tests for the dome of Fatima Khatun, a historic mausoleum in Historic Cairo dating back to the 13th century and consisting of mainly bricks and stones. The challenge was that the structure was difficult to access, and only a small portion of the top was accessible for the attachment of accelerometers. Current dynamic identification procedures typically adopt methods in which the sensors are arranged at optimal locations and permit direct assessment of the natural frequencies, mode shapes, and damping ratios of a structure. Approaches that allow for the evaluation of dynamic response for structures with limited accessibility are lacking. To this end, in addition to in situ dynamic investigation tests, a numerical model was created based on available architectural, structural, and material documentation to obtain detailed insight into the dominant modes of vibration. The free vibration analysis of the numerical model identified the dynamic properties of the structure using reasonable assumptions on boundary conditions. System identification, which was carried out using in situ dynamic investigation tests and input from modelling, captured three experimental natural frequencies of the structure with their mode shapes and damping ratios. The approach proposed in this study informs and directs structural restoration for the mausoleum and can be used for other heritage structures located in congested historic sites.
