Compared with the traditional cast-in-place construction technology with scaffolding, Accelerated Bridge Construction (ABC) has the advantages of small traffic impact, low total cost, high construction safety and quality, and can effectively realize the industrialization of construction. However, at present, the research on the life-cycle design performance, theoretical methods, disaster prevention and reduction of the bridges built by ABC as well as the replacement and restoration of old bridges is not mature, especially in the developing countries. ABC technology and bridge performance built by ABC are still in the exploration stage.

This session will focus on the state-of-the-art and practices of ABC technology, the innovative Accelerated Bridge Construction (ABC) methods, the structural performance, theoretical methods of design, disaster prevention and reduction, and relative guides or standards etc for the life-cycle of rapid construction bridges.

In recent years, infrastructure deteriorations and failures induced by natural hazards have drastically increased, due to the combination of a lack of adequate maintenance and disastrous events.

Structural Health Monitoring (SHM) can actively address these issues, contributing to the essential understanding of real-world behavior, validation of design assumptions, establishment of baseline modeling, assessment of structural performances and support of life-cycle management.

The aim of this Mini-Symposia is to bring together experts in SHM systems, performance assessment and risk management in various fields, in order to share knowledge and ideas and to foster future collaborations.

Contributions on SHM-supported performance assessments of structures and infrastructures are welcome, with the focus on both the theoretical progress and on real-world implementations.

With the rapid development in the construction of geoengineering related infrastructures, the construction quality of these structures and their safety operation become a major concern. To ensure this and prevent various potential disasters, the improvement of the level of engineering monitoring technology is a necessity. Recently, a series of distributed fiber optic sensing (DFOS) technologies, such as Optical Time Domain Reflectometer (OTDR), Brillouin Optical Time Domain Reflectometer (BOTDR), Brillouin Optical Time Domain Analysis (BOTDA), Raman Optical Time Domain Reflectometer (ROTDR), and Fiber Bragg Grating (FBG), have been developed. As these distributed technologies feature of sensing integrating with transmitting, with the characteristics of distributed measuring, long distance, insensitivity to corrosion, immunity to electromagnetic interference, etc., it has a bright and wide application prospect in the field of geoengineering monitoring. It is, therefore, of increasing interests to seek rational solutions for technical and practical problems related to distribute fiber optic sensing network in geo-engineering field. We invite the researchers in this field to participate in this special session and give presentations on up-to-date research findings, hotspots and difficult subjects related to DFOS-based geoengineering monitoring.

Global awareness of natural hazards has gained attention in the last decades. In the 2014-2018 period, the World Economic Forum has consistently ranked extreme weather 1 or 2 (both in likelihood and impact) in the survey of global risks. Because of the costly and sometimes catastrophic effects natural hazards pose to infrastructure, the civil engineering community is gaining awareness of the need to incorporate these events in life-cycle analysis. This SS will present current trends of research to incorporate natural hazards in the life-cycle analysis of civil infrastructure.

Civil infrastructure systems deteriorate due to aging, mechanical stressors, and harsh marine environment, among others. Major unplanned repairs or replacement of deteriorated infrastructures represent a significant economic loss. Our better knowledge on time-dependent reliability assessment of deteriorating structures is therefore indispensable for important decisions on repair and maintenance plans to preserve their structural performance and safety over certain thresholds and to prevent great economic loss. This special session aims to invite papers dealing with the time-dependent reliability assessment of deteriorating structures under uncertainties associated with multiple hazards, by utilizing updated information from experiment, inspection, or monitoring methods.

Infrastructure managers are responsible for executing interventions to reduce infrastructure-related risks. To plan these interventions, they need to estimate the risk related to all of their infrastructure assets, taking into consideration all hazards that might affect them, all ways they may fail, and all consequences of these failures. This MS/SS contains presentations of work focused on the integration of risk information into the planning of interventions on infrastructure networks, with special focus on the consideration of the spatial and temporal aspects of system behavior, and the amalgamation of the results of wide range of risk assessment methods.

Cracks are unavoidable for a concrete structure during its lifetime, which can weaken the structure by deteriorating mechanical properties and lower the durability by creating channels for harmful agents to attack the steel rebars or surrounding concrete. Therefore, the development of a concrete that has the ability to heal the cracks itself over time is highly desirable, while the self-healing phenomenon can extension the service life of concrete structures. This special session focuses on recent developments in the following topics, but not limited to:

  • 1) Novel healing approaches for mechanical and durability recovery of concrete;
  • 2) Novel analytical and numerical models that engages self-healing in concrete;

As a natural material, the long-term mechanical behavior of wood and engineered wood products has an obvious time-dependent performance. The load resisting capacity of timber structural members will decrease when they are subjected to long-term sustained load, and such phenomenon is mainly caused by the damage accumulation in the material. This session tries to provide recent cutting-edge research outcomes for the assessment and evaluation of life-cycle performance of timber and timber-hybrid structures, which will support the development of fundamental theories and applications of life-cycle civil engineering technologies.

Limited financial resources together with the pursuit of sustainable management of existing bridges imply the need to use optimised assessment strategies that respect different construction methods and design analyses. In practice, however, the assessment usually follows conservative approaches recommended in the codes and more advanced and modern methods, widely employed by researchers, are rarely used. Therefore, it is important to develop robust practical methods and guidlines for refined assessment of civil engineering systems. The objective of this Special Session is to present the latest innovative multi-level strategies and approaches associated with the assessment and lifetime prediction of concrete structures. In addition, the scope of this Special Session is to discuss, present and propose coupling strategies for the multilevel assessment of existing concrete structures. Such strategies include, for example, nonlinear finite element (NLFE) analysis, modern testing and monitoring methods, safety concepts etc.

The EU Atlantic Area has extensive road and rail infrastructure but is degrading over time. There is inadequate investment to address all its problems and increased climate-related hazard makes it more vulnerable than ever. Naturally, we must create decision making methods and prioritize investment, intervention/replacement which are aware of such hazards and their evolution over lifetime. This SS addresses the overall lifecycle analyses of this challenge in the widest sense, including monitoring, inspection, repair/rehabilitation and asset management but not limited to them. It will create an interdisciplinary dialogue and impact the global need of better management of road/rail infrastructure.
