“…Currently, there is a great deal of concern among researchers about historic buildings as they have a high patrimonial value. In this sense, it is worth highlighting the research carried out by Zini et al [46], in which the 'Torre Grossa' (San Gimignano, Italy) and the Mastio di Matilde (Livorno, Italy) were studied. In order to obtain a more complete structural diagnosis, it is common not only to take sensor data but also to carry out visual inspections of the structure.…”

This chapter presents and details a complete IoT solution for secure, synchronous, low-power, wireless and unattended structural health monitoring (SHM), whose architecture can be parameterised to any type of structure to be monitored, thanks to its modular design based on an embedded real-time operating system at the node level and a microservices architecture at the application level. This solution is validated by means of its deployment, together with two commercial reference systems, in two experimental use cases in two different structures: on the one hand, a bridge located at the Engineering School of the University of Seville (Spain) and, on the other hand, the Homage Tower of the Utrera’s Castle (Spain). The results obtained place this work as a novel solution in the current state of the art.

“…The modal identification methodologies can be divided into two categories as frequency domain and time domain techniques. While a literature survey of the methodologies is out of the scope of this study, Zini et al [30] compared the frequency and time domain modal identification techniques by applying them to two historic masonry towers. The well-known Enhanced Frequency Domain Decomposition (EFDD) methodology was used in this study by using Artemis, Modal Analysis Software [31].…”

This study deals with the dynamic characterization of the historic Tophane-i Amire building, located in Istanbul. The domed structure was constructed in the 18 th century and known as the first Industrial building in the Ottoman times. It was an arsenal building used for the production of cannons and their balls. An ambient vibration survey has been conducted with the Enhanced Frequency Domain Decomposition method to identify the dynamic characteristics of the structure. Later on, the finite element model of the structure has been constructed and numerical dynamic identification has been pursued. The obtained experimental and numerical results have been compared and the finite element model of the structure has been tuned to obtain a validated tool to represents the real dynamic behavior of the structure. While the tuned model of the structure intends to give a contribution for understanding its structural behavior and evaluate the mechanical properties of masonry, it has also been used for the evaluation of its seismic vulnerabilities. For this aim, the structure has been analyzed under maximum considered earthquake, and stress concentration regions have been determined. The results also serve a data for future structural health monitoring studies related to the structure.

“…gravity loads); 6) earthquake resistant design level (mainly gravity-load design or anti-seismic design); 7) soil-structure interaction. For unreinforced masonry (URM) buildings, the fundamental period can be affected by parameters such as masonry type, regularity in plan and in elevation, geometric and mechanical parameters, which are rarely accounted for (Bayraktar et al 2015;Zini et al 2018; Spina et al…”

FRIBAS database is an open access database (https://doi.org/10.5281/zenodo.6505442) made up of the characteristics of 313 buildings (71 masonry, 238 reinforced concrete and 4 mixed types). It collects and harmonizes data from different surveys performed on buildings in the Basilicata and Friuli Venezia Giulia regions (Southern and North-eastern Italy, respectively). Each building is defined by 37 parameters related to the building and foundation soil characteristics. Building and soil fundamental periods were estimated experimentally based on ambient noise measurements. FRIBAS gave us the opportunity to study the influence of the main characteristics of buildings to their structural response and soil-building interaction effect. In this study, we have used FRIBAS dataset to investigate how the building period varies as a function of building typologies and soil conditions. Our results motivate the need of going beyond a ‘one-fits-all’ numerical period-height (T-H) relationship for generic building typologies provided by seismic code, towards a specific characterization of T-H relationships that account for both soil and building typologies.
