“…Finally, the necessity of dealing with several sources of uncertainties that affect not only the model but also the experimental stage of monitoring has recently led to novel approaches that circumvent the issues in the preliminary model by relying on a data-driven optimisation. Such approaches identify the best placement for the sensors among a large number of instrumented DOFs, resorting to preliminary monitoring, thus considering real fieldwork signals [33,34].…”

“…Moreover, the lack of previous information about the dynamic behaviour of the structure may hinder proper test planning. A discussion of these two alternative scenarios (i.e., data-driven, high level of knowledge and experimentally intensive without numerical simulations required vs. model-based, low level of knowledge and computationally intensive without preliminary experiments) has been provided in [34].…”

As ageing structures and infrastructures become a global concern, structural health monitoring (SHM) is seen as a crucial tool for their cost-effective maintenance. Promising results obtained for modern and conventional constructions suggested the application of SHM to historical masonry buildings as well. However, this presents peculiar shortcomings and open challenges. One of the most relevant aspects that deserve more research is the optimisation of the sensor placement to tackle well-known issues in ambient vibration testing for such buildings. The present paper focuses on the application of optimal sensor placement (OSP) strategies for dynamic identification in historical masonry buildings. While OSP techniques have been extensively studied in various structural contexts, their application in historical masonry buildings remains relatively limited. This paper discusses the challenges and opportunities of OSP in this specific context, analysing and discussing real-world examples, as well as a numerical benchmark application to illustrate its complexities. This article aims to shed light on the progress and issues associated with OSP in masonry historical buildings, providing a detailed problem formulation, identifying ongoing challenges and presenting promising solutions for future improvements.
