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.

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.

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 must carry 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.

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

In recent decades, lots of concrete structures have been severely damaged by fatigue due to repeated heavy vehicle loads and various deterioration mechanisms such as frost damage, alkali-silica reaction, and corrosion of reinforcement accelerated by deicing salt and air-borne chloride. To solve this problem, in Japan, Cross-ministerial Strategic Innovation Promotion Program (SIP) -Infrastructure maintenance, renewal and management technology- started in 2014, and experimental methods and sophisticated numerical models for the damage mechanism of concrete structures under fatigue loads and several deteriorations are developed enthusiastically. This Mini Symposium aims at introducing the results of SIP as well as current and practical work on the methodologies and the technologies of design, construction, maintenance, and management for highly-durable concrete structures under harsh environments. Introductions of various examples from overseas for evaluating life-cycle performance of concrete structures exposed to harsh environments are also welcome.

Bridge structures are usually designed under a wide range of uncertainties regarding the extreme loads that they are required to sustain during their service life. One of the major challenges facing structural engineers, today, is to develop creative ways to reduce the risk of catastrophic damage due to these extreme loads, and to enhance the resiliency of urban infrastructure. However, this requires the prediction of the structural response from the linear-elastic range to levels approaching collapse and thus poses significant challenges. This mini-symposium focuses on the development and use of advanced computational and experimental techniques for structural assessment and evaluation of bridges under extreme loads.

Roads are managed by countries, expressway companies, prefectures, and municipalities. A number of road bridges managed by municipalities among them is many. Moreover, budget and engineer to maintain are few. Also there is no manual of management in most municipalities. Methods of inspection and judgment of road bridge in the municipality cannot be set as same at the expressway, because levels of safety are different.
This MS targets the maintenance of road bridges managed by the municipality. Not only technologies of inspection and repair but also management systems are discussed.

The principles and methodologies in bridge safety evaluation and risk assessment vary greatly in different regions of the world. Consequently, the corresponding code requirements and the practical considerations to satisfy their provisions can be quite different. Current performance-based bridge safety evaluation tends to be more reasonable for risk-informed decision-making in bridge rehabilitation and retrofit. Thus, development of the performance-based code requirements itself becomes critical.
This Mini-Symposium brings bridge engineers and researchers around the world to share and exchange their practices to provide a new avenue for improving the code requirements in bridge rehabilitation and retrofit communities worldwide. The specific topics may include, but not limited to: 1) integration of Structural Heath Monitoring (SHM) data into safety evaluation, 2) statistical characteristics of field measurements and probabilistic predications, 3) innovative approaches for code calibration at both strength and serviceability limit states, 4) performance-based provisions for construction detail requirements, and 5) risk assessment including life cycle cost analysis, especially for progressive collapse. Case studies and innovative approaches in risk-based assessment of existing bridges are highly encouraged.

Deterioration of metallic structures is a world-wide issue due to the exceedance of design life, increase in traffic mass limitsand fatigue issues. There are a number of conventional techniquesfor strengthening which can be used to remedy the above issues. However, such techniques have some disadvantages such as:time consuming, add extraweightto the structure, require heavy mechanical lifting, and have low resistance to fatigue failures. Strengthening with fiber reinforced polymer ‘FRP’ materials have proven to be a more effective techniquewhich eliminates some of the disadvantagesof the conventional methods.This session will focus on the state of theart studies and applications which focus on the strengthening of metallic structures using FRP materials.

Concrete bridges are being subjected to increasing demands such as: population growth, higher volumes of commuter and freight traffic and heavier vehicles. Further, environmental deterioration, damage and design defects all contribute to the rise of existing structures which require strengthening. Traditional bridge strengthening methods such as externally bonded steel plates, concrete and steel jacketing have largely been superseded by fiber reinforced polymers (FRP’s) due to their light weight, high tensile strength, resistance to corrosion and durability. FRP’s are typically applied to concrete members as externally bonded or near surface mounted reinforcement and have been used to strengthened bridges in flexure, shear and torsion. Due to the complexity involved in many bridge strengthening projects and the high strengthening demand, further research is needed into optimal FRP strengthening methods for bridges. The aim of this session is to focus on the latest research, development and field applications in the area of strengthening of concrete bridges using FRP and other innovative technologies. This may include, externally bonded and near surface mounted FRP systems, pre-stressed FRP, FRP anchorage systems, bond optimization, durability, numerical simulations, experimental testing, novel strengthening methods and field applications.

Recent accidents, collapses and events occurred have different origins and consequences. All of them are related to technical aspects, which resulted in a total interruption or at best a reduction of the service capacity of the transport infrastructure with the consequent personal injury or economic impact.
Bridge maintenance, safety and management has many lessons to learn from recent bridge accidents and disasters. This mini-symposium aims to reflect together academics, public sector, designers, contractors, financiers about this from the risk assessment perspective, accident description and repair bridge.
The risks to bridge from hazards are increasing globally and can occur with a varying degree of predictability.

New nondestructive evaluation (NDE) and monitoring methods are presented to evaluate potentially unhealthy or misevaluated structures. While damage identification and location are required to evaluate the damage impact, the 3D geometry of sub-surface defects is also critical for the assessment. Current NDE methods and analytical models provide limited information on discretized internal damage. Due to these limitations, innovative approaches are presented for damage detection in various structures by discrete dialing-in methodological parameters that may utilize assistance of agents such as metamaterials to precisely identify damage at high-penetration depths, leading to accurate structural analyses.
