“…The electrochemical characteristics of corrosion are elevated with the help of electrochemical sensors, which make use of techniques such as galvanic current measurement, linear polarization resistance (LPR), electrochemical impedance spectroscopy (EIS), and electrochemical noise (EN) [10,67,[69][70][71]. Electrochemical sensors are fairly advantageous; they can include the measured corrosion rates, and they also have the ability to investigate the mechanism responsible for the resultant corrosion.…”

There has been enormous growth in the energy sector in the new millennium, and it has enhanced energy demand, creating an exponential rise in the capital investment in the energy industry in the last few years. Regular monitoring of the health of industrial equipment is necessary, and thus, the concept of structural health monitoring (SHM) comes into play. In this paper, the purpose is to highlight the importance of SHM systems and various techniques primarily used in pipelining industries. There have been several advancements in SHM systems over the years such as Point OFS (optical fiber sensor) for Corrosion, Distributed OFS for physical and chemical sensing, etc. However, these advanced SHM technologies are at their nascent stages of development, and thus, there are several challenges that exist in the industries. The techniques based on acoustic, UAVs (Unmanned Aerial Vehicles), etc. bring in various challenges, as it becomes daunting to monitor the deformations from both sides by employing only one technique. In order to determine the damages well in advance, it is necessary that the sensor is positioned inside the pipes and gives the operators enough time to carry out the troubleshooting. However, the mentioned technologies have been unable to indicate the errors, and thus, there is the requirement for a newer technology to be developed. The purpose of this review manuscript is to enlighten the readers about the importance of structural health monitoring in pipeline and wind turbine industries.

Summary Traffic‐induced vibration is one of the main causes of small (often only cosmetic) damages for Heritage buildings. The heavy public road‐transport, often very close to these structures, may lead to fatigue phenomena due to induced continuous vibrations and consequently damages. Even if all the International Standards agree to define the velocity—expressed in terms of Peak Particle Velocity (PPV) or Peak Particle Component Velocity (PCPV)—as reference damage indicator, a standard procedure for calculating those values starting from accelerometers data is indeed absent (or needs to be better specified). This paper—taking into account that in most cases velocities cannot be directly measured—first compares the efficiency of two of the most common employed methods: the trapezoidal rule and the long Discrete Fourier Transform. This comparison is performed discussing the experimental activity performed on the SS. Annunziata's lodge in Florence (Italy) which is particularly exposed to traffic‐induced vibrations. Subsequently, a systematic analysis of the traffic‐induced vibration phenomenon was performed based on (i) dynamic identification by means of accelerometers data; (ii) calculation of the velocities (PPV and PCPV); (iii) analysis of the traffic component effects; and (iv) analysis of the Structure‐Soil Interaction (SSI) by using results obtained by means of Falling Weight Tests (FWT). Eventually, a comparison with the results of a previous dynamic test campaign performed in 1994 is reported, underlining a consistent increase of the traffic‐induced vibrations on the lodge possibly caused by the increase of the road unevenness.

“…Structural health monitoring (SHM) became an inevitable part of the continuous control of structural conditions in numerous industrial fields, including means of transport, nuclear energy, civil engineering, and many other [ 1 , 2 , 3 ]. The aim of an SHM system is to collect data from various sensor sources and carry out the necessary processing, including the extraction of key features, damage detection, and prediction.…”

Optimal sensor placement is one of the important issues in monitoring the condition of structures, which has a major influence on monitoring system performance and cost. Due to this, it is still an open problem to find a compromise between these two parameters. In this study, the problem of optimal sensor placement was investigated for a composite plate with simulated internal damage. To solve this problem, different sensor placement methods with different constraint variants were applied. The advantage of the proposed approach is that information for sensor placement was used only from the structure’s healthy state. The results of the calculations according to sensor placement methods were subsets of possible sensor network candidates, which were evaluated using the aggregation of different metrics. The evaluation of selected sensor networks was performed and validated using machine learning techniques and visualized appropriately. Using the proposed approach, it was possible to precisely detect damage based on a limited number of strain sensors and mode shapes taken into consideration, which leads to efficient structural health monitoring with resource savings both in costs and computational time and complexity.
