Advances in new sensing platforms and computer vision methods are enabling a new paradigm in structural monitoring and damage detection. Buildings, bridges, naval vessels, nuclear reactors, dams, oil tanks, and space structures require visual inspection. Automating the monitoring and damage detection process will enhance the safety of humans and the structural integrity against leaks, spills and even disasters. For instance, unmanned aerial vehicles (UAVs) can quickly collect large volumes of images of a structure. Additionally, stereo camera systems and Lidar are able to generate 3D reconstructions of a structure. The limitations of human visual inspection resolve around consistency, accessibility, safety and efficiency. Thus, the advantages of automating the data collection and data analysis process include greater access to remote and difficult-to-reach regions, while enforcing consistency and saving considerable time and resources. Across hazard response, construction, and structural monitoring researchers are gaining experience with existing techniques, and building upon them to tackle realistic challenges associated with automated damage identification and classification in structures.

Do Hyoung Shin, INHA University, Incheon, Korea
Combinations of various sources and different types of data measured from a structure and its surrounding environment are partly or whole together utilized to monitor and/or evaluate structural condition or performance. Under such a circumstance, health monitoring of a structure is a complex and multi-layer problem. Particularly for civil structures, health monitoring has been a great challenge because its local problem usually negligibly influences the global aspect in many cases. In addition, environmental effects frequently dominate the structural behavior. However, on the other hand, a lot of measured information floods in the monitoring and evaluation process. Therefore, it is highly required to develop an efficient method to control these multi-data in the health monitoring of a civil structure.

SS22: Uncertainty-Involved Structural Model Updating, Damage Assessment and Reliability Evaluation
Gang Liu
, School of Civil Engineering, Chongqing, China
Sheng-En Fang, School of Civil Engineering, Fuzhou, China
In the past decades, model updating and damage detection strategies have been extensively investigated for the purposes of structural health monitoring. So far, most of the existing model updating and damage detection methods are developed within a deterministic framework. However, uncertainties always exist in real-world engineering structures, which highly limits the practical applications of deterministic methods. Due to it, probabilistic and non- probabilistic theories have been introduced into the updating or assessment procedures in order to take into account the influence of different kinds of uncertainties. This special session provides a broad discussion on the topics of uncertainty-involved model updating and damage assessment methods for engineering structures. Extensive discussions are also welcome in the aspect of structural reliability evaluation, which can be regarded as a supplementary procedure for structural safety after damage assessment.

Structural displacement, oftentimes provided in the design, is an important structural quantity. For example, the restoring forces primarily depend on the displacement; the usability is often prescribed in terms of the displacement. However, the displacement of full-scale structures are not easily measured because reference points for structural displacement measurement are typically unavailable. Recent development of displacement estimation algorithm, device, and systems are expected to allow for practical displacement estimation on structures. In this special session, the displacement estimation methods and their applications are discussed. Possible technologies involved include but are not limited to accelerometers, inclinometers, optical device, Laser, Radar, wireless sensing, and signal processing.

Ting-hua Yi, Dalian University of Technology, Dalian, China
The environmental actions (wind, temperature, rain, earthquake, etc.) and the bridge usage (traffic loadings) can continually modify the behavior and cause deterioration of long-span bridges in their long-term lifespan. Thus, research and application of bridge health monitoring and safety assessment are inevitable requirements for the sustainable development of bridge engineering. Many monitoring systems have powerful ability in rapid and large-capacity data measurement, transmission and storage. However, these monitoring systems can only measure and store mass monitoring data, and are difficult to serve for the structural condition assessment and safety warning for long-span bridges. The special session aims to discuss the theory, methodology and technique for monitoring-based bridge condition assessment and safety warning, which will be helpful to improve the scientific and technological level in structural health monitoring of bridge structures.

Branko Glisic, Princeton University, NJ, USA

Daniele Zonta, University of Strathclyde, Glasgow, UK


Structural damage commonly results in local changes in the strain field, and therefore placing strain-sensitive sensors close to a possible damage location enhances the probability to identify its occurrence. However, it is likewise very difficult to predict the exact location of a damage prior it arises. Very dense arrays of sensors hold promise to meet this challenge, as their coverage of the monitored structure, or part of the structure, significantly increases the chances of being in contact with damage. Hence, very dense arrays of sensors have potential for an accurate and reliable detection, localization, and quantification of damage.

A number of innovative technologies featuring dense arrays of sensors have emerged in the last two decades: (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.; (iii) 2D and 3D active wave sensing techniques, embedded MEMS, and self-sensing materials. 

The aims of this special session are (1) to evaluate the progress of the methods enabling dense arrays of sensors, (2) to identify potential future research areas (e.g., related to their applicability on real structures) and (3) to cross-fertilize the research and practice through an exchange of ideas. The topic of the session is not limited to sensors and sensing techniques, but also includes data analysis and management, and power harvesting techniques that can address large-scale implementations.

SS36: Highway Infrastructure Monitoring
Nizar Lajnef, Michigan State University, MI, USA
Davide Lo Presti, University of Nottingham, Nottingham, UK
Autonomous structural health monitoring has received significant attention in recent years due to the declining state of aging civil infrastructure. As new “smart” structures are being designed, special consideration has been paid toward embedding health monitoring capabilities directly into the construction material during the manufacturing and deployment process. Currently, pavement instrumentation for condition monitoring is done on a localized and short-term basis. The available technology does not allow for in-field continuous long-term monitoring. Though there has been significant research activity in distributed wireless sensors for monitoring industrial process parameters and environmental conditions, all of the commercially viable sensors developed to date are geared toward the monitoring of bridges and buildings, while little attention was given to the pavement problem.
Recently, faced with economic challenges and the upcoming changes in the way roads are designed and built requiring contract deliverables based on long term performance measures, the pavement industry and several research groups started looking into innovative effective pavement monitoring techniques.
Several new initiatives were launched in the US and Europe such as ‘Highways of the Future’ by the US Federal Highway Administration, and ‘Forever Open Road’ by the Forum of European National Highway Research Laboratories. These programs are fostered by the fact that the road has to reinvent itself periodically in response to innovations, societal issues and rising user expectations. The objectives are to move toward a road that is adaptable, automated, and climate change resilient, based upon a concept for building and maintaining roads that can be applied whether to motorways, rural or urban roads, regardless of region or country.
Topics that can be included in this session include: (i) Pavement sensors; (ii) Communication and energy exchange between the infrastructure, the vehicle and the network manager; (iii) Recyclable materials with the potential for self-diagnosis and repair; (iv) Pavement surface that remains permanently optimal irrespective of climatic variations; …
Participants can be researchers, industry, road network owners and users.

More attention for future researches in this filed may be devoted to (1) resiliency of the structural control system, (2) seismic performance of the structural control system under strong earthquakes, (3) interaction between the control system and the main structural system. This session aims to share the knowledge of research and applications of structural control techniques in China in the past decades and to discuss on related future trends.

Long-span bridges are often key transportation infrastructure assets of a country, stimulating regional cooperation and economic and social development. The inevitable aging process and the accumulation of damage resulted from wind, traffic and surrounding environment adversely affect their performance. The closure or collapse of these bridges can lead to significant impacts, including major disruption to traffic, economic losses and, in some cases, heavy casualties. Therefore, the Structural Health Monitoring (SHM) is vital to ensure the safety, serviceability and sustainability of these structures, reducing the risk of malfunction due to extreme loading and long term degradation. This special session is structured to form an international discussion on some of the major challenges that SHM communities are currently facing, particularly for long-span bridges, and how state-of-the-art data processing algorithms and frameworks are addressing them. The topics of this session include, but are not limited to: (i) optimal in-situ sensor arrangements, (ii) big data analysis and SHM of long-span bridges, (iii) quantification of uncertainties in monitoring parameters, (iv) reliability assessment and SHM of long-span bridges, and (v) the future of SHM of long-span bridges.
