The aim of this Mini-Symposium is to attract papers that deal with the use of advanced computational and/or experimental techniques for evaluating the life-cycle performance of aging structures and infrastructures in an aggressive environment. For these structures, multiple environmental and mechanical stressors lead to deterioration of structural performance. Such deterioration will reduce their service life and increase the life-cycle cost associated with maintenance actions. This Mini-Symposium covers current theoretical and experimental efforts made in the assessment and future prediction of performance, maintenance and strengthening of structures and infrastructures in an aggressive environment.

A main goal of vibration-based structural health monitoring and damage identification is assessed structural condition via vibration signatures. For civil structures response-only data is often used due to difficulties associated with forced excitation of large structures. This followed by inference of grey/black-box models, or updating of physics-based models. This mini-symposium welcomes novel contributions on vibration-based structural health monitoring, damage identification and parameter, input and load estimation, using black-box as well as physics-based models. Relevant topics include linear and nonlinear system identification, parameter and state estimation, model updating and correlation, optimal experiment design, and the exploration of novel sensing techniques.

Reinforced concrete (RC) structure has been extensively used in the civil engineering. However, owe to the corrosive medium in the atmosphere, underground water, sea water and deicing salt, durability and bearing capacity of the reinforced concrete structure are facing challenge. The service year of the RC structure cannot satisfy the designed service life. To this end, models and methods to describe the performance of concrete, steel bar and time-dependent reliability during structural life-cycle is the main topic. Those who have been working on related fields are cordially invited to exchange their ideas and research outcome in this mini symposium.

Due to the frequent occurrence of hazards and their effects on life-cycle performance, sustainability, risk, and resilience issues have become increasingly important. Considering climate change effects, hazard intensity and probability of simultaneous occurrence of multiple hazards are expected to increase. This mini-symposium brings together researchers from academia and industry to address problems of structural design, safety, and management under multiple natural hazards in a life-cycle context. Potential topics include: vulnerability and risk assessment, performance-based engineering, and hazard mitigation and management. Emphasis will be placed on topics dealing with effects of multiple hazards, climate change, risk assessment, cost-benefit analysis of adaptation, and life-cycle engineering. Practitioners as well as researchers in the areas of structural and sustainable engineering are encouraged to participate.

A large amount of civil infrastructure in the public domain has flood risk reduction, water management, navigation or mobility related functions, or a combination of these. Existing infrastructure generally has long life spans and is not always designed to adapt for changes in use, climate or regulations. A considerable part of the infrastructure is reaching the end of its service life. Considerable investments are required for building, renovating and maintaining these infrastructures.

This Mini-Symposium will focus on the life cycle assessment and management of infrastructure like dikes, bridge piers/piles, sluices, locks retaining walls, sewage and drinking water, harbor infrastructures, reservoirs and dams, etc; The focus of their management is shifting from condition and risk management, to predictive and adaptive management and from asset level to system or regional level. These trends require to search for smart solutions from technical, financial and governance point of view, to meet present day adaptive, societal and environmental requirements. The objective of this Mini-Symposium is to collect and exchange best approaches and innovative practices in Life-Cycle Engineering in water infrastructure.

The papers in this Mini-Symposium will show:

  • new Life-Cycle management approaches to the problem, like adaptation pathways for changing demands and requirements, scenario analysis, societal cost benefit approaches, system optimization and planning;
  • new Life-Cycle engineering approaches for life time prediction: intervention levels, deterioration models, inspection and monitoring;
  • new life time extension approaches: condition assessment, repair and renovation techniques, design, probabilistic modeling and maintenance optimization.

Keeping the function of buildings and infrastructures uninterrupted is of significance to their long-term service performance. As buildings and infrastructures are influenced by environment all the time, it is necessary to study the characteristics of environment and its possible effect on buildings and infrastructures. The concept of Value Protection of built environment deals with a number of uncertainties related to life-cycle and risk assessment and represents an interesting issue both for new buildings and infrastructures and for existing ones. For engineers as well as for any stakeholders involved in constructions process, this topic represents a real key-feature for a sustainable development, especially for seismic areas and, in general, for areas/single constructions exposed to extreme events (natural or caused by humans).

The aim of this Mini-Symposia is to bring together researchers in related field to share their accomplishments, findings and ideas. Contributions on but not limited to Value Protection, life-cycle management, sustainable development, and effect of extreme events on buildings and infrastructures are welcome.

Current practice on the assessment of existing concrete structures subject to aging, deterioration and damage processes often lacks thorough life-cycle reliability and risk-based evaluations. The assessment is often performed on the basis of guidelines which rely on the (subjective) experience of the investigator and improvements are necessary to quantitatively incorporate in this process available data and results from inspection, monitoring and/or laboratory investigations.

In this mini-symposium, focus is given to new developments in relation to:

  • Modelling of deterioration processes and associated structural responses of concrete structures;
  • Development of quantitative methods to assess existing concrete structures in relation to reliability and risk-based performance criteria;
  • Application of Bayesian updating approaches to incorporate and exploit information from inspections, monitoring and/or testing for updating instantaneous and time-dependent performance predictions;
  • Modeling of spatial variability in properties and degradation of concrete structures in relation to performance predictions;
  • Time-dependent performance prediction approaches;
  • Conceptual assessment strategies;
  • Case studies.
  • Novel hydraulic structures;
  • Theoretical analysis and numerical simulation of hydraulic structure under different loadings;
  • Durability issues of the hydraulic structures;
  • Project management and quality control;
  • Influence of hydraulic engineering on ecology.

The mini-symposium will also report on advances and new developments within fib and SEI/ASCE technical committees working on life-cycle assessment of existing concrete structures.

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.

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.
