“…For instance, the full-field measures provided by digital image correlation is a rich source of information for model updating [28]. Strain measures provided by fiber optic allied to damage identification is revealed to be a potential solution for civil structural health monitoring [29]. The results are consistent even in the presence of corrupted measures [30,31].…”

Over the past few decades, the Constitutive Relation Error (CRE) theory has proven to be a valuable numerical technique for model identification in engineering systems. Under certain conditions, this technique allows predicting the global state of connections starting from an observed structural vibratory response. These conditions often assume deterministic knowledge about input parameters and mechanical modelling. As with most inverse problems, the inherent uncertainties in the system can drastically affect the parameters of interest, posing an additional difficulty in the identification process. The present study proposes a simple and direct way to include and evaluate the effect of uncertainties in the CRE-based process of identifying parameters of semi-rigid structural connections. The numerical investigations are carried out in two parts. The first, from an exclusively deterministic perspective, shows the main characteristics of the method such as the possibility of using partial data and the inclusion of flexible support conditions. The second part explores the limits of the suggested formulation in a non-deterministic context considering both measurement noise and material uncertainty. The results show that the presented CRE formulation can identify the parameters properly in various situations. However, high noise levels in the reference measures may deteriorate identification process.

“…Waeystens et al [ 28 ] used fiber optic sensors to measure mechanical strain in an 8 m simply supported post-tensioned concrete beam. The strategy developed by the authors aimed to update physical parameters associated with damages in concrete (usually related to changes in the mechanical properties of the material) to minimize the gap between the numerical strains obtained from finite element analysis and the strains from sensor outputs.…”

Detailed information about concrete behavior in real structures is an important issue in controlling its performance during its service life, and the use of embedded sensors to obtain desired information such as temperature, onset of the cracking process and evolution of strains, has gained the attention of the building concrete industry. Data obtained using this technology can provide valuable information for decision making about the need for corrective interventions that can ensure the integrity and safety of concrete structures for long period of time. This paper presents a review of the current state-of-the-art of embedded fiber optic sensors used to assess concrete information of a wide range of aspects, comprising: existing alternative technologies, characteristics and advantages, practical applications and future developments. Complementarily, the work presents preliminary results of the use of fiber optic sensors to automatically and continuously perform expansion readings of AAR in concrete elements that facilitate both the storage—with elimination of the usual interruptions for manual readings—and the availability of continuous results of expansion data that are not possible to obtain with usual AAR tests code reading recommendations.

“…The selected LoDs for the representation of buildings are chosen such that the lowest LoD will not introduce any additional DoFs, but represent the buildings by means of additional stresses due to building weight, while the higher LoDs have a detailed representation of the building structure and include the relevant soil-structure interaction effects (see Figure 10). In the current state of development, a liner elastic material model is used for building representation, which can be used for damage detection using model updating techniques [48]. For direct estimation of a damage index, non-linear damage models are to be developed in future extensions of the framework.…”

This paper presents a concept for parametric modelling of mechanized tunnelling within a state of the art design environment, as the basis for design assessments for different levels of details (LoDs).To this end, a parametric representation of each system component (soil with excavation, tunnel lining with grouting, Tunnel Boring Machine (TBM) and buildings) is developed in an information model for three LoDs (high, medium and low) and used for the automated generation of numerical models of the tunnel construction process and soil-structure interaction. The platform enables a flexible, user-friendly generation of the tunnel structure for arbitrary alignments based on predefined structural templates for each component, supporting the design process and at the same time providing an insight into the stability and safety of the design. This model, with selected optimal LoDs for each component, dependent on the objective of the analysis, is used for efficient design and process optimisation in mechanized tunnelling. Efficiency and accuracy are further demonstrated through an error-free exchange of information between Building Information Modelling (BIM) and the numerical simulation and with significantly reduced computational effort.The interoperability of the proposed multi-level framework is enabled through the use of an efficient multi-level representation context of the Industry Foundation Classes (IFC). The results reveal that this approach is a major step towards sensible modelling and numerical analysis of complex tunnelling project information at the early design stages.
