“…The common denominator of these buildings is the use of contemporary materials, such as concrete or steel. In this context, without being exhaustive, the following examples can be highlighted: the Infante D. Henrique Bridge, a concrete arch bridge in Portugal [54]; a steel cable-stayed footbridge over the Hron River in Slovakia [55]; the roof of the Municipal Sports Stadium of Braga, also in Portugal [56]; the Morrow Point Dam in the United States [57]; a tall building in Qatar [58].…”

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.

“…Operational modal analysis (OMA) entails determining the modal properties of a structure, such as its natural frequency and mode shapes, within its regular operational (ambient) conditions (i.e., without any forced/external excitations). 144 The greatest advantage of OMA over the forced vibration approach is that the measurements are collected without disrupting the functionality of the structure. OMA is an output-only approach which consists of measuring velocity and acceleration, and the input is considered nearly “flat.” The output-only OMA can be classified under two classes: (1) parametric time-domain methods (2) and nonparametric frequency-domain methods.…”

Inland navigation structures (INS) facilitate transportation of goods in rivers and canals. Transportation of goods over waterways is more energy efficient than on roads and railways. INS, similar to other civil structures, are aging and require frequent condition assessment and maintenance. Countries, in which INS are important to their economies, such as the Netherlands and the United States, allocate significant budgets for maintenance and renovation of exiting INS, as well as for building new structures. Timely maintenance and early detection of a change to material or geometric properties (i.e., damage) can be supported with the structural health monitoring (SHM), in which monitored data, such as load, structural response, environmental actions, are analyzed. Huge scientific efforts are realized in bridge SHM, but when it comes to SHM of INS, the efforts are significantly lower. Therefore, the SHM community has opportunities to develop new solutions for SHM of INS and convince asset owners of their benefits. This review article, first, articulates the need to keep INS safe to use and fit for purpose, and the challenges associated with it. Second, it defines and reviews sensors, sensing technologies, and approaches for SHM of INS. Then, INS and their components, including structures in ports, are identified, described, and illustrated, and their monitoring efforts are reviewed. Finally, the review article emphasizes the added value of SHM systems for INS, concludes on the current achievements, and proposes future trajectories for SHM of INS and ports.

“…While the finite element method is commonly used to study the behaviour of structures, [14][15][16] the FEMU method is one of the most widely used methods in the literature by which the initial model is updated according to the observed data to minimize the difference between the existing structure and the numerical simulation. [17][18][19][20] Therefore, it is very useful in SHM and damage detection systems. [21][22][23] An overview of the FEMU process steps in the present research is shown in Figure 1.…”

Cantilever beams can have various behaviour depending on the details of the connection. Partially-fixed connections have a different performance from conventionally-fixed connections, in which the exact information is not available. In this paper, using the finite element model updating (FEMU) of a steel cantilever beam, the support conditions of a partially-fixed connection and the behaviour of the beam are investigated. The FEMU is utilized as an appropriate technique for structural health monitoring, which requires the use of data acquisition methods from the structure. In this research, instead of using discrete sensors, displacement and strain information are continuously measured from the beam surface using the digital image correlation (DIC) method. The difference between the initial model and the data extracted from the DIC is determined by a cost function. A hybrid method called Powell particle swarm optimization is used to minimize the cost function. This method includes particle swarm optimization (PSO) as a global search technique and Powell optimization as a local search technique; the hybrid method achieves better performance by combining the two methods. A dynamic inertia weight is presented to improve the performance of the PSO algorithm. Abaqus software and Python programming have been used to carry out the FEMU process. Finally, the amount of rotation and displacement of support are calculated, and the dependency of beam behaviour on each of the variables is investigated. This method yields acceptable convergence of the results and can be extended to study other structural components.
