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.

 

Authors developing  with novel techniques regarding the assessment and  monitoring of bridges should submit 300-word abstracts to the chairs of the Mini-symposium by May 31, 2009.

 

Selected, high quality papers, presented in the mini-symposium will be considered for publication in a special issue of the International Journal "Structure and Infrastructure Engineering - Maintenance, Management, Life-Cycle Design & Performance".

This mini-symposium is the continuation of a successful mini-symposium conducted in IABMAS 2008 in Seoul, Korea. Bridge health monitoring (BHM) is typically used to track and evaluate performance, symptoms of operational incidents, anomalies due to deterioration and damage, as well as health during and after extreme events. It is possible to capture seasonal and environmental changes not readily apparent from intermittent tests. Bridge health monitoring, which is a special case of structural health monitoring, can be expected to integrate sensing technologies, analysis methods and information technology for infrastructure management.

There are numerous real-life BHM applications around the world. New advances in sensor and information technologies and the wide use of the Internet make BHM a promising technology for better management of bridges. Large-scale applications have been presented at a number of specialty conferences and workshops. In spite of the recent activity in this area and the successes achieved, this technology is not gaining acceptance by bridge owners and practicing engineers. We need to close the gap between theory and practice. There are many challenges remaining that must be overcome for successful BHM applications. As a result, there is still a lot of research to bee conducted and then demonstrated before routine applications of BHM can be expected to take place.

This mini-symposium if focusing particularly on the research needs for BHM systems and benchmark studies, and integration of BHM analysis methods for decision making. The mini-symposium covers the following topics and other related topics in the broad area of "Research and Application for Bridge health Monitoring."

      • Long term monitoring applications of bridges
      • Management and maintenance oriented monitoring applications - Research in reliability based bridge health monitoring
      • Research in local and global monitoring for bridges
      • Benchmark studies for collective research
      • Research in novel technologies such as GPS, computer vision, novel materials

The bridges as all the things in the world are more or less damaged during their operation. There are a lot of reasons (including environmental aggressiveness) that generates the bridge damages. To maintain the bridges in safety operation conditions they sometimes have to be rehabilitated by repair or both repair and strengthening.

There are a lot of techniques and procedures which could be applied for the bridge repair and strengthening. The main purpose of the Mini-Symposia is to share the experience in this domain and to find new techniques and materials in order to rice the quality of rehabilitation and to ensure the durability of the bridge construction.

Assessment of performance and estimation of the remaining service life of bridges relies upon a thorough understanding of the structure’s current condition and knowledge of the loads to which it is being subjected. Weigh-in-motion (WIM) is an important tool for monitoring traffic loads traveling over bridge and road infrastructure, and informs the prediction of remaining service life of structures. While mature technologies exist for roadway applications, development of widely applicable WIM technology for bridges remains an open research activity. Current efforts in the area of bridge-WIM rely primarily on the use of strain gauges applied to the structure, with the resulting strain measurements being used to infer the weight of passing vehicle loads. While extraction of reliable vehicle weights for simpler, single or multiple-span bridges has been achieved, further effort is needed to bring about methods for WIM on large and more complex structures. This symposium will address current research efforts in the development of WIM systems for bridges, with particular focus on the use of the response of the structure to infer vehicle loads.

Bridge management is highly dependant on information and the quality of this. Information on inventory, condition, performance, maintenance need, etcetera. A special feature of infrastructures like bridges is the extreme long life-time of often a 100 years or longer. During this life-time many changes occur; deterioration and repair, changes in traffic use and societal demands. Historical events can have it effects many years later. These characteristics form a huge challenge to the tools for information like inspection and monitoring techniques, information systems as well as to the organization of these.

The mini-symposium addresses these topics in three sessions:

      1. State of the art of BMS (Bridge Management Systems)
        The results of glossary of the BMS's of the world that is being compiled by the BM committee will be presented.

      2. Advanced tools
        Promising developments will be presented in this block

      3. Discussion session on needs and future development
        This session will be different from regular sessions. It consist of some short introductions, followed by a well facilitated, plenary discussion

Bridge damageability under seismic condition is often expressed in the form of seismic fragility curves.  The fragility curves play a major role in the predictive simulations of  bridge damage and resulting degradation of  traffic flow capability of highway transportation networks under future damaging earthquakes. Such simulations are useful for pre-event assessment of seismic disasters on which optimal emergency response strategies can be developed by government agencies to mitigate potential earthquake disasters.There are however a number of sources of uncertainty associated with bridge fragility models currently in use.  This mini-symposium will serve as a forum in which new information is presented and exchanged in order to identify the sources of the the uncertainty and quantify their contributions to the total level of uncertainty in the assessed seismic performance of the highway network. This Mini-Symposium will also encourage  presentations on the uncertainty  involved in the damageability modelling under other hazards such as wind, vessel collision, and scouring.

Summary
The societal challenges presented by aging civil infrastructures in the US are pervasive - cutting across our nation’s transportation, water, and power systems. Many industrialized countries in the world face similar problems. Although focusing events such as the 2007 collapse of the I-35W Bridge in Minneapolis and the 2005 inundation of New Orleans by Hurricane Katrina received much attention, these events are in fact just warning signs for societal risk due to the failure of infrastructures that have been long under-funded, and components of which were maintained, repaired or replaced without recognizing them as interconnected, interdependent, multi-scale and multi-domain systems.

As an example, on December 23, 2008 a 44-year old 66-inch water main break in Bethesda, MD created a 4-ft high torrent on the highway, trapping 15 vehicles. Helicopters used buckets to save some of the drivers, while the county's Swift Water and Technical Rescue teams used boats and ropes for others. Serving 1.8 million suburban Maryland customers, the Washington Suburban Sanitation Commission has been plagued by an increasing number of water main breaks. In 2007 these reached a record of 2,129. Many of the older urban water and sewer utilities in the Eastern USA face similar problems. When we consider that congestion costs the U.S. over $200 billion per year (USDOT 2006), over 80,000 U.S. bridges are designated as structurally deficient (FHWA 2007), 41% of wastewater utilities are not solvent (USGAO, 2004), and over 1/3 of water utilities routinely defer maintenance due to insufficient funds (USGAO 2004), and the increasing frequency of power blackouts covering large urban areas, the increasing enormity of the problem becomes clear.

There have been recent calls and promises of significant funding for infrastructures, most notably as a part of President Obama’s economic recovery package. However, a valid question that keeps coming up relates to prudent and transparent decision-making for selecting alternative strategies for infrastructure financing or revenue generation, as well as for prioritizing expenditures for existing infrastructures for repair, rehabilitation, replacement, decommissioning, as well as removal from use and converting to green space. Infrastructure planning, engineering and management decision-making is an extremely complex problem since we now recognize that decisions involving “multi-domain systems” may lead to many unintended consequences over different time-scales. While we recognize the need for a systemic approach to infrastructure decision-making, and we have even borrowed the term “asset management” from economics and finance as a term for such an approach, we still face major challenges before we can formulate a set of universal principles for asset management.

Asset management is a complex paradigm, requiring stakeholder consensus on the values, policies, strategies and tactics related to infrastructure services, performance metrics and associated management trade-offs. No single discipline and certainly no one sub-discipline can claim ownership of this problem. A multi­disciplinary group of engineers, scientists and stakeholder representatives from academe, government and industry have to join forces to develop consensus definitions and principles for infrastructure asset management. Some of the Sessions that would come together in this mini-symposium to dissect the problem of infrastructure asset management are tentatively listed in the following.

An Analysis of the Highway Transportation Infrastructure in the USA
Organizer and Chair: Hamid Ghasemi, FHWA This Session is expected to review the statistics, conditions and performance of the Highway Transportation Infrastructure in the USA. Facts regarding owners, jurisdictions, financing and revenue sources and current management approaches will be analyzed. Resource needs and current vision of the FHWA to deal with any challenges will be summarized. Presenters are anticipated from Pavements, Bridges and Operations/ITS Research groups in addition to some select state DOT representatives.

Current State of Highway Transportation Asset Management in North America
Organizers and Chairs: Stephen Gaj, FHWA and Chris Wade, Director of Infrastructure, Calgary This Session will offer an overview of the current status of asset management in the USA and Canada. Various activities by Federal and State agencies, AASHTO and TRB in USA and efforts in Canada by CRC, various agencies and municipalities will be presented.

Current State of Highway Transportation Asset Management in Europe (2 Sessions)
Organizers and Chairs: Leo Klatter, Centre for Public Works, the Netherlands and Jens Sandager Jensen, COWI A/S, Denmark, Helmut Wenzel, VCE, Austria This Session will summarize and synthesize the current status of asset management in various European Countries. We anticipate presenters from Denmark, the Netherlands, GB, Germany, Austria, France and Switzerland to be invited for these Sessions.

Current State of Highway Transportation Asset Management in the Far East (may be 2 Sessions)
Organizers and Chairs: Hyun-Moo Koh, Seoul National University, Korea, Hitoshi Furuta, Kansai University, Japan and Ou Jinping, Harbin Insititute of Technology, PR of China. This Session will summarize and synthesize the current status of asset management in various Far Eastern Countries. We envision presenters from Japan (3), Korea (3), PRChina (2), Australia and New Zealand (2).

Highway Transportation Asset Management: Towards the Future
Organizers and Chairs: Ali Maher (Rutgers), Emin Aktan, Frank Moon, Patrick Gurian and Franco Montalto (Drexel/IIS), Dan Frangopol (Lehigh), Samer Madanat (UCBerkeley), Ross Corotis (UC Boulder), Louise Comfort (U of Pitt), and Susan McNeil (University of Delaware)

1. Identification of the Multi-Domain Infrastructure System:
Human Elements: Institutions, Culture/History, Organizations, Individuals
Natural Elements: Climate, Environment, Air, Water, Soil, Plants and Animals
Engineered Elements: Highways, Bridges, Safety, Operations and ITS

d. Sustainability: Ecology, Society, Economy. The goal of the above Sessions would be to identify the systems that come together in multi-domain infrastructures from the viewpoints of their respective experts. System-identification has been a research area in electrical engineering and structural mechanics, offering great potential for validated modeling and simulations of multi-domain systems for scenario analysis. In this Session experts from each domain will discuss the terminologies, world-views and mind-models that prevail. Can we develop and share a common language and value system? Given that Sustainability is emerging as a value system promising to link each domain of infrastructure systems, how this paradigm may be leveraged as the principal objective function for asset management will be explored. European, US and Canadian research on Sustainability will be presented.

2. Roadway to Sustainable Asset Management:
Performance Metrics incorporating Uncertainty and Risk
Data and Modeling Needs for Performance Based Asset and Risk Management
Technology Integration Needs and Technology Development Strategies
Panel: International Organization for Research, Development and Demonstrations

Evaluation and measurement of bridge performance is the most critical attribute in addressing bridge deficiencies and in providing the ability to design and build bridges with optimal life cycle costs, higher performance, lower maintenance, and generally optimal operation in the future; however, there are gaps in knowledge due to data uncertainties. Uncertainty in measuring bridge performance is not well defined, understood or documented. It relies too heavily on expert opinion and not on objective data and is based on significant assumption or generalization based on a very simplistic understanding of bridge behavior.

To enhance our knowledge of bridge performance, the Federal Highway Administration (FHWA) has initiated the Long-Term Bridge Performance (LTBP) Program. The LTBP Program is an ambitious 20+ year research effort that is strategic in nature with specific short and long-term goals. The program will include detailed inspection, periodic monitoring, evaluation and testing, and forensic investigation of representative samples of bridges throughout the United States to capture and document their performance. The program will result in a high-quality, quantitative database, which will lead to the development of improved life-cycle cost and performance models, better understanding of bridge deterioration, improved effectiveness of maintenance and repair strategies, support for improved design methods and bridge preservation practices, and development of the next generation of bridges and bridge management tools.

This symposium will focus on four topics related to activities of the LTBP program:

Computational nonlinear analysis methods are usually required to realistically predict the serviceability and ultimate structural behavior of bridge structures. For reliability and safety evaluations, these methods must allow a proper modeling of the unavoidable uncertainty related to the geometrical and mechanical parameters of the structural problem. Moreover, a time-variant formulation of the nonlinear analysis is often necessary to properly account for the effects induced by mechanical and environmental damage and by eventual repair and maintenance interventions under uncertainty. To validate these computational methods, the results of the numerical prediction need to be compared with the evidence from in field testing and measurements. Contributions presented at this Mini-Symposium are expected to deal with recent advances for numerical prediction and in field validation of bridge performance in damaging environments.

Old bridges in Mexico were designed without following seismic provisions. In addition, bridge deterioration, overloading due to heavy traffic and economic and demographic growth produce an increment on the risk exposure of many bridges, some of them located on areas with high seismic hazard.

Managers and operators of the Mexican bridge system are realizing about the need to rely on better methods and techniques to asses the safety and performance of bridge infrastructure and cost-effective strategies to optimize scarce resources for maintenance.

This mini-simposia will address the current trends of bridge research at three Mexican institutions.

Mini-Symposium Cable Supported Bridges:

Major Cable Supported Bridges are usually the crucial elements to the road and railway infrastructure. Very often they constitute a part of critical links between highly habited areas. As a consequence their closure or traffic capacity reduction causes major inconveniences for the users and result in significant losses to the economy. Furthermore, construction, maintenance and rehabilitation is rather costly. Therefore, the design, maintenance, man-agement and rehabilitation of this kind of structures are complex and chal-lenging tasks. Consequently, they have to be performed using state-of-the-art technical solutions and the best practice gained over many years of ex-perience.

The Mini-Symposium will present the experience collected by engineers during involvement in design, maintenance, rehabilitation and management of major Cable Supported Bridges all over the world. Several papers will present state of art and best practice case studies related to the maintenance, management, rehabilitation and design of Cable Supported Bridges.

Super long span bridges are expected to meet special requirements due to their socio-economical importance, harsh environment, structural complexity and uniqueness. Among these, the lifetime of long span bridges, which is demanded to be more than 150 years in typical, is a key issue in bridge engineering including materials, design, analysis and maintenance. This mini-symposium intends to review and discuss the current issues and the state-of-the-art technologies focusing on the lifetime design of cable supported long span bridges. Crucial topics, such as design specifications, long-term performance and risk analysis, and durable concrete and lifetime steel design methods, will be covered. The super long span bridge project, a 7 year-R&BD project funded by the Ministry of Land, Transport and Maritime Affairs of Korea, will also be introduced in which core engineering technologies are developed based on lifetime design concept.
