“…The potential applications of vibration-based SHM methods encompass the monitoring of slender structures, such as historic masonry towers [ 13 , 14 , 15 ] and buildings, such as palaces and churches [ 16 , 17 , 18 ], and bridges [ 19 , 20 , 21 ]. The practical applications of strain-based SHM methods to similar structural settings can be found in the literature [ 22 , 23 , 24 , 25 , 26 ]. Computer vision-based SHM approaches are also frequent in the literature, with interesting applications to masonry structures and more [ 27 , 28 , 29 , 30 , 31 , 32 ].…”

A diffuse and continuous monitoring of the in-service structural response of buildings can allow for the early identification of the formation of cracks and collapse mechanisms before the occurrence of severe consequences. In the case of existing masonry constructions, the implementation of tailored Structural Health Monitoring (SHM) systems appears quite significant, given their well-known susceptibility to brittle failures. Recently, a new sensing technology based on smart bricks, i.e., piezoresistive brick-like sensors, was proposed in the literature for the SHM of masonry constructions. Smart bricks can be integrated within masonry to monitor strain and detect cracks. At present, the effectiveness of smart bricks has been proven in different structural settings. This paper contributes to the research by investigating the strain-sensitivity of smart bricks of standard dimensions when inserted in masonry walls subjected to in-plane shear loading. Real-scale masonry walls instrumented with smart bricks and displacement sensors were tested under diagonal compression, and numerical simulations were conducted to interpret the experimental results. At peak condition, numerical models provided comparable strain values to those of smart bricks, i.e., approximately equal to 10−4, with similar trends. Overall, the effectiveness of smart bricks in strain monitoring and crack detection is demonstrated.

“…In the work proposed by (Gong et al 2019), the author proposed an optical sensor system for monitoring excavations for the construction of tunnels, and subway stations, among other underground structures. Optical sensors are also widely used in monitoring historic buildings, as proposed by (N. L. Li et al 2018;Jiang et al 2020), who applied this technology to ancient wooden buildings in China, as well as (Verstrynge et al 2018; Dalgic et al 2023) who used this technology for monitoring masonry historic buildings. In terms of interrogation techniques, (Díaz et al 2017) developed a low-cost system for dynamic applications, spanning from industrial applications to biomedical and the Internet of Things (IoT) (Díaz et al 2019).…”

Low-cost optical interrogator system for structural health monitoring

et al. 2023

Optical ber sensors have great potential for application in civil construction, especially in the eld of structural health monitoring. However, one of the barriers to the diffusion of these sensors is allied to the fact that their implementation is quite expensive, mainly due to the high price of commercial optical interrogators. Therefore, the present work seeks to develop a low-cost optical interrogation system. For this, the present study proposes the development of this system based on the use of tunable lters and edge lters in the monitoring of low and high frequencies, and consequent digital processing of the collected signals through the nd_picks algorithm and the Fourier transform. As a result, it was possible to observe the adequate functioning of the tunable lters, with the validation of the system using a FBG, and a previous simulation for the edge lter system with frequencies superior to 100 kHz.
