  • MS02 - Smart materials and sensing solutions for Intelligent Infrastructures

    Filippo Ubertini, Carmelo Gentile, Carlos Moutinho

    SHM applications to large infrastructural systems, including bridges, dams, wind turbines, and energy systems, are still quite limited due to their high costs, localized nature of the measurements using off-the-shelf sensing technologies, and the inability of global analysis algorithms to detect local damage. In order to address these challenges, significant research efforts are being carried out focusing on the integration of smart multifunctional materials and SHM systems. This can be achieved by leveraging state-of-the-art materials engineering advances, including new nano-/micro- structural composites (e.g. self-sensing smart concretes and smart pavements), smart sensors, including self-powered sensor networks, real time vibration-based systems, novel methods for system identification and operational modal analysis using distributed smart sensor networks, modern information and communication systems, machine learning and signal processing technologies, advanced structural analysis, and more. The MS specifically addresses those topics, including major open challenges, such as the improvement of smart materials and sensor systems, the accuracy of data sampling, the development of effective diagnostic methods based on smart materials and sensors, the analysis and management of big data for structural performance evaluations and more.

  • MS03 - Nondestructive evaluation of structure materials

    Christian Boller, Wolfgang Habel

    Nondestructive evaluation (NDE) is a precursor to SHM. It includes the complete gamut of nondestructive testing (NDT) techniques including mainly those based on mechanical (modal, acoustic) and electromagnetic (magnetic, eddy current, radar, microwave, terahertz, thermography, optical, x-ray) waves. Those techniques are associated with a significant amount of data generated and signals to be processed as well as converting those data to images and combined with statistical aspects, such that it can be understood by a broader public in the end. This holistic process can be considered to be NDE. Many of the NDT techniques (i.e. acoustic emission, guided waves, fibre optics, etc.) have been converted into SHM applications. However, developments in NDE are a continuous source to challenge SHM ideas. This mini-symposium will therefore target on how to characterize and evaluate materials in a non-destructive way specifically considered for infrastructure applications in view of quality assurance and condition monitoring, the latter to be also considered in the context of residual operational life assessment or even operational life extension.

  • MS09 - SHM enhanced by machine learning and artificial intelligence

    Yi-Qing Ni, Yong Huang, Xiao-Wei Ye

    In addition to innovative sensing technology, there is an urgent need to develop advanced analytic tools which enable data-driven damage detection (diagnosis) and prediction (prognosis) in a real-time or near real-time manner. Machine learning has currently emerged as one of the principal theoretical and practical approaches for designing machines that learn from data acquired through sensing. In particular, the probabilistic machine learning paradigm, which is capable of describing how to represent and manipulate uncertainty in modelling and prediction, has a central role in massive data analytics. This mini-symposium provides a platform to exchange the latest research on the application of various machine learning and artificial intelligence methods for SHM, such as convolutional neural networks, compressive sensing, sparse learning, ensemble learning, transform learning, deep reinforcement learning, generative modelling, and big data analytics.

  • MS11 - Advances in SHM strategies and its application to Civil Infrastructures

    Chul-Woo Kim, Mehrisadat Makki Alamdari, Yi Zhang, Patrick J. McGetrick

    Structural Health Monitoring (SHM) of civil infrastructures has been examined and applied by academia and bridge authorities as well as those in industries in terms of a potential solution to modify labor-intensive inspection with labor- and cost-effective inspection making full use of Sensing Technology, Information and Communication Technology (ICT) and Internet of Thing (IoT). Although adoption of SHM approaches in industry is on the rise, despite significant research activity, SHM technology has not yet been widely accepted by working level officials and authorities; this is probably caused by few satisfactory results in real-world applications. Furthermore, since the data are all collected in experiment or field environments, uncertainty quantification and management of in-situ measurements also play a critical role in the extraction of features which can influence decisions in the process of prognosis and diagnosis of instrumented structures. The aim of this Mini-Symposium is to provide a forum in which scientists and engineers from academia and industry can present their state-of-the-art research results on SHM technology, focusing on real-world applications and successes.

  • MS12 - Cost-benefit of SHM systems

    Francisco J. Carri?n Viramontes

    The use of SHM systems is increasingly growing worldwide, the cost of sensors and monitoring systems is also decreasing, and there are many software applications and algorithms, each time more effective for damage detection and identification. Nonetheless, some investors and bridge operators and managers are still reluctant for SHM systems and, in some cases, is not easy to foresee the long-term benefits. A key aspect for cost-benefit analysis for new SHM Systems is the availability of information on specific cases, statistical data on short and long-term maintenance savings, system updating costs, analysis costs, damage detection reliability and its economic impact if early detection is achieved, etc.
    Main objective of this symposium is to bring together researchers, experts, industry and operators to discuss cost-benefit issues for SHM systems, analyze specific cases and to design strategies for data collecting for long-term benefit and cost evaluation.
    Research and application papers are encouraged on the following topics:
    • Cost-benefit SHM cases
    • SHM data processing and analysis costs
    • SHM Instrumentation and/or system updating costs
    • Damage detection reliability-cost analysis
    • Long-term cost forecast
    • Cost-analysis methodologies for SHM systems
    • Maintenance-SHM cost balance

  • MS13 - The use of SHM in bridge evaluation

    Baidar Bakht, Aftab Mufti

    In this mini-symposium, the impact of SHM application on enhancing the bridge evaluation will be discussed. Bridge design codes provide an equation for estimating the load carrying capacity of bridges which are based on the resistance of elements, applied dead loads and traffic loads. In situ monitoring of bridges, provides a better understanding on capacity of the elements, the load distribution among elements of bridges, etc. The data provided by SHM sensors can be used for evaluating the load carrying capacity of bridges more precisely.

  • MS20 - SHM-aided life-cycle performance assessment

    Dan Frangopol, Fabio Biondini

    Civil infrastructure systems, due to their inherent vulnerability, are at risk from aging, fatigue and deterioration processes. The exposure of civil infrastructure to combined effects of discrete and continuous damaging events under uncertainty pose a major challenge to the reliable prediction of the performance and service life of structural systems. To reduce this uncertainty, it is necessary to integrate life-cycle predictions with the results of inspection and data from SHM. This Mini-Symposium is aimed at exploring the value of SHM in the life-cycle assessment, inspection and maintenance of civil infrastructure including buildings, bridges, roads, railways, and dams, among others. Emphasis is placed on the use of cost-effective monitoring systems for data acquisition to support better decision-making strategies on the life-cycle and service life of civil infrastructure systems.

  • MS21 - From structure observation to Physics-based SHM models and digital twins

    Matthias Baessler, Yuri Petryna, Ying Wang, Ge Ou

    Structural Health Monitoring (SHM) can be successful for real structures if it is based on numerical models with physical meaning. Such models facilitate a better understanding of the local and global structural behavior and enable a better interpretation of the measured data. ‘Digital Twins’ are recently considered as a step forward in SHM uniting a physics-based model with a sensor network and continuous data flow to a direct mirror of the physical system. However, the term Digital Twin is frequently used in different context and with different goals. The aim of this MS is to provide an overview on current concepts, practical experience and challenges of SHM with physics-based models and digital twins applied to large engineering structures.

  • MS22 - Blind source separation for SHM: A benchmark study

    Yi-Qing Ni, Genda Chen, Sriram Narasimhan

    Blind Source Separation (BSS) is a fundamental problem that has broad applications in many fields, such as machine learning, pattern identification and signal processing. The aim of BSS is to reconstruct signals (sources) of interest and their mixing function from sole (response) observations. Typical BSS methods, such as the Independent Component Analysis (ICA) technique, the Second-Order Statistics (SOS) technique, and the Bayesian approach have recently attracted increasing interest for application to SHM-relevant problems. This mini-symposium focuses on a benchmark study of SHM-oriented BSS by using two sorts of real-world data: (i) acceleration response data acquired from a five-story steel-frame model for the separation of multiple dynamic excitations and for locating the separated excitations; (ii) strain response data collected from a long-span bridges for the extraction and separation of different ingredient (sources), including temperature-induced ingredient, highway traffic-induced ingredient, railway traffic-induced ingredient, and wind-induced ingredient, which is greatly beneficial to damage detection and reliability assessment. Participants can apply their own BSS approaches to the above data.
