Assessment and monitoring concepts for bridges become more and more important in the intervention planning (e.g., maintenance, repair, rehabilitation, replacement) for new and existing bridges. Nevertheless, there is still a strong demand for the development and efficient use of novel techniques for monitoring and assessment of bridges. These techniques affect intervention and maintenance strategies and in consequence cost optimization concepts. Therefore, the objective of this Mini-symposium is to highlight the recent developments in science and practice and to formulate the next necessary steps. This Mini-symposium provides the opportunity to disseminate and discuss novel techniques regarding assessment, monitoring and maintenance techniques of bridges.

Maintenance of infrastructures is an important and urgent issue, because there are many bridges to be maintained. However, it is not easy to maintain all the bridges in good conditions due to many problems. Therefore, innovative technologies for these problems are expected. New technologies have been developing using AI (Artificial Intelligence) and IoT, such as deep learning and UAV. The deep learning can be promising due to such an advantage that it can find out important feature characteristics automatically. This mini-symposium aims to discuss together academics and practitioners about the future of AI technologies for bridge maintenance and safety.

The main objective of this Mini-Symposium (MS) is to contribute the “Smart City” for build-up rationally and worldwide the frame-work for a sustainable urban life to be carried over into the next generation through creating and applying science & technology. “Smart Bridge Health Monitoring” project will be able to become a key technology for realization of the “Smart City” project based on the bridge monitoring collaboration among us (multidisciplinary approach such as ICT, sensors, materials, mechanical, structural systems, etc). For this purpose, we have a plan to make discussions about a long term monitoring system for existing bridges combined with the latest information processing technologies, such as vehicle-based health monitoring techniques for short and medium span bridges (shorter than 30 m span length) and integrated real-time monitoring data and numerical bridge analyses for long span bridges with the utilization of FEM, BIM and LCA methods. Then we propose a “Mini-Symposium on Bridge Health Monitoring Conjunction with Smart Cities” for discussing from various points of view.

The railway structures have different transition zones and interaction of elements, for example: railway pavement, geotechnical, bridges and rail vehicles. We will discuss how the dynamic coefficient propagates between each zone, and how can we control the safety at all stages of the structural life of the elements, be it design, execution and maintenance, besides verifying the importance of studying the stiffness between different types of (flexible and rigid). Measuring the transfer function between each element allows us to properly dimension and measure maintenance during the service life of the elements.

Corrosion of reinforcing steel leading to structural deterioration and failure of reinforced concrete structures is a serious problem for bridge owners. Short life of conventional repairs and durability of concrete bridges have been a concern for bridge engineers. Many transportation departments, universities and corrosion professionals are working on developing cost-effective strategies that can prevent and mitigate the rebar corrosion in concrete bridges. Electro-chemical corrosion protection technologies have been applied in bridge s since 1970s to extend the life of repairs and prolong overall service life of bridges. This mini-symposia aims to share new research findings, developments, and applications in this field.

Loading is the most variable term in the structural reliability problem. Since resistance modelling is fairly well understood, in the assessment of existing bridges in particular, the accurate estimation of loading can obviate or reduce the need for replacement and rehabilitation measures, potentially offering bridge owners (and society) enormous savings. Continuing on from the success of this mini-symposium at IABMAS 2014, this mini-symposium will examine all forms of loading for pedestrian, highway, and railway bridges, including, but not limited to, long-and short-span bridges, vehicle and traffic modelling and measurements, dynamics, statistical analysis, earthquakes, pedestrians and non-linear modelling methods. Those involved in the measurement and modelling of loading, both static and dynamic and the calibration of theoretical models, are particularly encouraged to submit their work for presentation in this mini-symposium.

【MS07】Prolonging the life of steel and steel composite bridges

The traffic density is growing during the last decades. As a consequence numerous new roads and railwaylines were built or are planned to be realized in the near future. On the other hand existing bridges mustcarry the increased traffic. Most of these bridges were not originally designed for the high service loads and the amount of traffic of today. Many of the structures are aged and, depending on the maintenance and repair carried out, do not longer suit the purpose. Refurbishment and strengthening is required. According to statistics short span bridges are the most frequent category. This MS deals with results of a recent research project on the framework of RFCS (EU Commission) called PROLIFE focusing on determination of bridge condition through the measurements(monitoring) and structural assessment carried out for innovative solutions and improved methods for repair and strengthening especially of beam and truss steel bridges. The methods are mostly based on a stepwise evaluation with increasing effort in basic data collection and recalculation if the higher level of accuracy is required. The solutions to update and retrofit existing bridges will be presented and deepen with lectures of this MS. This MS is reserved for partecipants of Prolife project.

Structural health monitoring (SHM) can provide information for identifying various structural performance parameters, thus enhancing the asset owner’s decision-making in the life-cycle management of the structure. However, the choice of SHM may often be put aside in the view of their seemingly high costs and unclear benefits. The concept of Value of Information (VoI) provides a more holistic perspective by quantifying the expected benefits of SHM alongside its costs. The proposed Mini-Symposium is intended for works on (but not limited to) the recent trends and findings in VoI research, existing challenges, novel VoI frameworks, computational aspects, and actual implementation.

Management of bridges damaged by aging and initial defects is one of the global issues. Bridge management technologies such as inspection tools, repair and strengthening methods are developed in each country, however, their applicability is affected by regional technological capability, human resources, environmental conditions, and so on. In this MS, trial examples of implementation of elemental technologies in other countries and related industry-government-academia collaborative activities are introduced. It is expected that issues for applying the technologies to the other countries and their possible solutions are explained. Consequently, future prospects of international expansion of bridge asset management technologies are discussed.

Structural Health Monitoring (SHM) has been evaluated by bridge authorities, as well as those in industry, as a method with potential to improve the safety and reliability of structures and thereby reduce their operational cost. 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 bridge 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 inevitably arises in the process of data collection, data modelling and analysis. 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.

The aim of this Mini-Symposium is to attract state-of-the-art papers dealing with the use of advanced computational and/or experimental techniques for evaluating the life-cycle performance of existing bridges in an aggressive environment. For these bridges, 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 existing bridges in an aggressive environment.
The following topics would be addressed :
- Life-cycle analysis of existing bridges based on reliability approach
- Long-term deterioration model of bridge performance
- Related topics with laboratory or field experiments on aging bridges

Highway bridges constitute key elements of a transportation network that are often subjected to multiple stressors along the service life. Threats to adequate performance may stem from continuous aging phenomena, intermittent natural hazards, or anticipated man-made perils such as freight growth. Moreover, climate change consequences due to increased emissions and global warming can further exacerbate bridge performance leading to loss of resilience under service loads or extreme events. This mini-symposium invites contributions towards consideration of multiple hazards across the service life, influence of climate change on hazard modeling techniques, and uncertainty quantification for satisfactory risk and reliability predictions of bridge structures.
