Organizers
Fu-Kuo Chang, Aeronautics and Astronautics, Stanford University, USA
Amir Nasrollahi, Aeronautics and Astronautics, Stanford University, USA
Scope of Session
Cyber-physical systems (CPS) are a synergistic technology between physical and computational systems. The bio-inspired distributed sensors, actuators, and embedded devices are networked to sense, monitor, and control the physical world, whereas the computational world provides an autonomous solution through artificial intelligence (AI). CPSs have the ability to communicate between physical and AI-based virtual worlds like human-to-object and object-to-object interactions. Real-time state estimation, structural diagnostics, and prognostics with distributed sensors are the key components of a reliable CPS system in SHM applications. Furthermore, a reliable CPS system can be applied to another similar CPS system for real-time diagnostic using the large data of the sensor network. It is envisioned that CPSs will have a tremendous impact on many critical sectors such as state estimation and awareness of UAVs, self-diagnostics, and prognostics of structures, renewable energy harvesting, smart manufacturing, multi-functional materials with built-in SHM systems, transportation, autonomous driving, aerospace, smart city, etc. This special session encourages paper but not limited to the following areas to build up reliable CPS:
- Verification and validation of AI-based systems
- System safety and state awareness
- Sensors, sensor network, actuators, and embedded devices for CPS
- Integrated analysis and predictive capabilities
- Real-time detection, decision making, and control
- Self-diagnostics and prognostics of AI-based SHM systems

Session Title
Integration of Physical Modeling, Monitoring and Machine Learning for SHM
Organizers
Eloi Figueiredo, Lusófona University, Portugal
Ionut Moldovan, Lusófona University, Portugal
Scope of Session
Long-term structural health monitoring (SHM) has been mainly performed using two approaches: model- and data-based. A challenge in both approaches is to make the distinction between the variations of the structural response caused by damage and environmental or operational variability. Hybrid techniques for SHM that integrate model- and data-based approaches have emerged to complement the data measured by the monitoring system installed on the structure with data obtained from its numerical model, leading to both unsupervised and supervised machine learning strategies for damage identification. The hybrid approach to the SHM is still in its early development. Some of the challenges are related to the calibration of the numerical models such as producing reliable data. This Special Session intends to bring together publications involving the integration of numerical modeling, monitoring, and/or machine learning, in order to highlight the current capabilities and future trends. Besides theoretical contributions, the papers must address the practical engineering application of the techniques, using actual experimental or field monitoring data.

Session Title
Assessment of the Value of Structural Health Information
Organizers
Sebastian Thöns, Lund University, Sweden
Michael Todd, University of California San Diego, USA
Maria Pina Limongelli, Politecnico di Milano, Italy
Scope of Session
Information gathered using Structural Health Monitoring (SHM) systems can substantially contribute to an enhanced performance of civil structures and other infrastructure, transportation, and machinery systems by providing an improved benefit generation and the reduction of operational costs and risks throughout their life cycle. However, the link of Structural Health Information (SHI) to the performance enhancement of technical systems is often missing, which prevents a systematic quantification of the value of SHI. This may lead to a lack of addressing and demonstrating the SHI systems impact and value.
The value of SHI can be quantified with the Bayesian decision analysis necessitating the modeling of decision scenarios involving (1) models of technical and SHI system life cycle performance, (2) an objective function of a decision-maker, and (3) decision variables associated to the SHI strategies and technical system performance management strategies. The value of SHI provides the basis for a targeted and optimized SHI system development optimizing the benefit generation, costs, and risks for the technical system management.
With this special session, the research efforts for quantifying and optimizing the value of SHI will be gathered and discussed. Contributors in the fields of SHM optimization, decision analysis, uncertainty modeling, and risk and reliability research are welcome.

Session Title
Seismic SHM for civil structures
Organizers
Maria Pina Limongelli, Politecnico di Milano, Italy
Mehmet Celebi, Earthquake Science Center, USGS, USA
Scope of Session
During the last two decades, the need for seismic structural health monitoring (S2HM) both property owners, as well as researchers and professionals, have evolved. As a result, numerous monitoring systems have been installed in structures in various seismic prone countries that utilize real-time or near-real-time responses recorded during strong earthquakes to make informed decisions related to the health of structures. Data collected from S2HM systems have strategic importance both for the advancement of knowledge on the behavior and performance of structures under strong seismic actions and for the calibration of realistic and reliable numerical models that are aimed to reproduce the structural behavior and to formulate a diagnosis about possible damages. Furthermore, the possibility to assess the seismic vulnerability based on data recorded on the monitored structure opens new avenues in maintenance policies, shifting from a traditional ‘scheduled maintenance’ to a ‘condition-based maintenance’, carried out ‘on-demand' or ‘automatically’, basing on the current structural condition. The aim of this Special Session is to report recent advances in this field and successful applications for civil structures and infrastructures: buildings, bridges, historical structures, dams, wind turbines, pipelines. The session deals with theoretical and computational issues and applications and welcomes contributions that cover but are not limited to, seismic SHM algorithms for identification and damage detection, requisite strong-motion arrays and real-time monitoring systems and projects, instrumentation and measurements methods and tools, optimal sensors location, experimental tests, integration of seismic SHM in procedures for risk assessment and emergency management.
Such a session will provide a venue for the exchange of information on ongoing developments and assess successes and limited successes of SHM.

Distributed and Quasi-distributed Fiber-optic and Electrical Sensors, and Associated Data Analysis and Management
Organizers
Branko Glisic, Princeton University, USA
Daniele Zonta, University of Trento, Italy
Scope of Session
Damage frequently occurs in form of strain-field anomalies. Strain-sensitive sensors installed at the location of damage have an unusual high change in their output signal and thus, can detect the damage reliably. However, it is difficult to know the exact location of damage prior to its occurrence. To address this challenge, very dense arrays of sensors could be used. Their “omnipresence” on the structure and their high sensitivity to damage, makes them very promising for reliable and accurate detection, localization, and quantification of damage. Several innovative techniques for enabling distributed and quasi-distributed arrays of sensors emerged in the last decade or so: (i) 1D distributed fiber optic sensors, (ii) 2D distributed sensing skins, paints, and sheets based on nano-technologies, large-area electronics, photonic crystals (nanospheres), conductive polymers, etc., and (iii) 2D and 3D active wave sensing techniques, embedded MEMS, and self-sensing materials. The aims of this special session are (1) to assess the state of the art of the techniques enabling dense arrays of sensors, (2) to identify challenges related to their applicability in real-life settings, and (3) to cross-fertilize the research field through an exchange of ideas. In a broader sense, the topic of the session includes data management and power harvesting techniques that can address the challenges related to execution, processing, and analysis of a large number of measurements performed by very dense arrays of sensors.

Session Title
Acoustic Emission and Hybrid SHM
Organizers
Victor Giurgiutiu, University of South Carolina
Hanfei Mei, University of South Carolina
Scope of Session
This special session will address the topic of acoustic emission and hybrid SHM. Acoustic emission (AE) is a passive SHM technique that relies on ‘listening’ to the elastic waves generated when an incremental crack growth occurs, or impact damage happens in composites. The elastic waves associated with AE events can travel a considerable distance in metallic structures that have a low damping dissipation coefficient. AE waves also travel in composite materials, but their travel distance may be less due to the higher damping dissipation of polymer matrix composites. Hybrid SHM techniques encompass a large class of methods that aim at combining several techniques to increase the probability of damage detection. For example, one may use passive SHM to record a damaging event (such as an impact in a composite structure) and then apply active SHM to try to estimate the magnitude of the resulting damage and its severity. Or one can listen to AE events that indicate that cracks are progressing into the structure and then follow up with the active SHM technique to evaluate the crack size. Or one can use two different active SHM techniques (e.g., pitch-catch wave propagation and electromechanical impedance standing waves) to better detect the damage location and size. But these are just examples. The session is open to all innovative techniques aimed at enhancing SHM capabilities. Contributions that judiciously combine theory and experiments are highly encouraged.

Physics-Enhanced Machine Learning for SHM

Fu-Kuo Chang, Stanford University, USA
Scope of Session
Recent interests in Artificial Intelligence and Machine Learning (AI/ML) promote a data-driven approach to stochastic and deterministic analysis; however, for complex and time-dependent scenarios, AI/ML techniques may not meet performance needs. Contrasted to data-driven approaches are model-based approaches based on the first-principle modeling evident in theory, simulations, and analysis. For future structural health monitoring (SHM), a coordination of model-driven and data-driven approaches are needed such as Physics-Enhanced Machine Learning (PEML). Various efforts have explored related techniques such as Dynamic Data-Driven Applications Systems (DDDAS), (Physics-Informed Machine Learning), and PINN (Physics-Informed Neural Network). Papers are sought that utilize PEML for understanding, modeling, and control the behavior of complex systems towards structural health monitoring (SHM). Applications include sensor systems, big computing, full-scale simulations, networked sensors, or designs towards situational, materials, and systems awareness of engineered systems. Preference is given to papers that highlight comparative analysis over real data with modeling approaches and heterogeneous sensor implementation.

SHM for Heavy and Critical Equipment
Organizer
Keqin Ding, China Special Equipment Inspection & Research Institute
Scope of Session
Heavy and critical equipment mainly includes boiler, pressure vessel, oil pressure pipeline, crane, large-scale recreational facilities, and other equipment. It is an important infrastructure related to life safety and great danger and closely related to people's life and the national economy. Once an accident occurs, it will easily cause economic losses, casualties, and even seriously affect the political economy and social stability. With the rapid development of the global economy and the need for major engineering construction, the possession of large-scale and high-parameter equipment has increased rapidly. The service environment of heavy and critical equipment is complex and harsh, such as high temperature, high pressure, high dust, flammability, explosion, corrosion, and so on. In the course of service, the failure modes of equipment structure are various and accidents occur frequently. Most of the heavy and critical equipment inspection still stays on the traditional inspection mode of on-site, static, and off-line, which has high labor intensity and low inspection efficiency. The existing inspection and detection technology does not match the development of automation and intelligence of special equipment. It is urgent to develop remote, real-time, and online health monitoring technology to ensure the safe and reliable operation of equipment. The main objective of this session is to exchange and discuss the latest development of heavy equipment structural health monitoring, health diagnosis, damage identification, fault prediction, and health management technology.

Scope of Session
With the rapid development of the world economy, technical standards have become a powerful hand to promote the close integration of science and technology and economy and enhance international competitiveness. It plays an increasingly important role in promoting the industrialization and marketization of scientific and technological innovation. In recent years, due to the development of large-scale, high parameter, and complex equipment structures, the demand for structural health monitoring is more and more urgent. However, due to the lack of structural health monitoring standards to guide the implementation, the technology and standards are seriously out of touch, which affects the wide application and promotion of a series of research results with great engineering application value. The standardization of structural health monitoring started late, and there are still some problems that can not be ignored. It is mainly manifested in the lack of a technical standard system, the need to improve the quality level, the need to explore the operation mechanism, and the lack of policy system guarantee. In order to promote the application of structural health monitoring technology and promote the sustainable development of the industry, research on standardization of structural health monitoring is urgently needed. The main objective of this session is to exchange and discuss the latest development of standardization of structural health monitoring, health diagnosis, damage identification, fault prediction, and health management technology.
