Themes for Technical Session

One key note speaker will be selected from among the papers submitted for each theme

Topic 1

Deterioration Modelling for bridges in Tropical Environment.

Show More...

Deterioration is an ongoing process and happens in all the structures especially in concrete from the day it is cast and till it fails. Deterioration models assist Bridge management implementers to predict the future of specific bridges with respect to its present condition in the given geometrical environment. Sufficient research is available in other geography however impact within the tropical climate is an emerging scenario. In recent years topics such as robustness, resilience, sustainability, life cycle assessment have shifted into the focus of engineering societies. Many concepts have been developed. Yet, accurate and physically based prediction models and modelling concepts for the time dependent behaviour and deterioration of concrete structures, which are quintessential inputs, are still scarce. This Session covers current research made in the modelling of deterioration in tropical climate zone in bridge management. The session aims to bring together academics, practitioners and researchers to deliberate on the newer model or modification to the present available deterioration models with respect to Bridge Management Systems. Under the Chair of Sachin Joshi the session is expected to be very interesting and informative. His research within IBMS shall be the trend setter for this session.

CHAIR: Mr. Sachin Joshi

Topic 2

Risk Analysis & Optimization of Fund allocation.

Show More...

Once the deterioration prediction takes place, it is important that Risk evaluation is done to decide which of the bridge stock needs attention in the immediate future and which of the bridges can be attended to in differed time period. Ageing and deteriorating bridge stock call for more intense inspections and maintenance. As the use of the network intensifies, demands of network performance increase. Means and resources are scarce both in terms of money and trained staff. The introduction of (elements of) risk management will help to make bridge management more effective and efficient. This Session covers current theoretical efforts made in the assessment and future prediction of risk involved in bridge management. The session aims to bring together academics and researchers to deliberate on the innovations that are being propagated in risk management with respect to Bridge Management Systems. Under the Chair of Prof. Dr. Siddhartha Ghosh the session will bring to the front various innovation that institutes are presently conducting research.

CHAIR: Prof. Siddhartha Ghosh

Topic 3

Management of large database for bridges.
Show More...

The management of bridge networks is a challenging aspect for any organisation in any country. Assessment, insight and understanding of large bridge stocks collectively or in a network are becoming increasingly important.  As the number of bridges in a network increases, management of large database becomes a challenge to engineers and software designers. On the other hand, such databases can collectively provide a powerful tool to investigate how a bridge stock is behaving collectively.  Data mining and analytics become significantly relevant problems and solutions that cater to such large stock of bridges become more involved. For example, IBMS has over 154,000 bridge structures only on National Highways which is just 2.5% of road network in India. There is variety around the assessment techniques, business practices, governance guidelines and other aspects that have not been looked into in detail yet. This Session covers current efforts (theoretical and in practice) addressing in the solving and investigating these issues and aspects within bridge management. The session aims to bring together academics, practitioners and researchers scientist from world over to deliberate on the problems of large database. The Chair of this session Prof. Vikram Prakashi intends to create a discussion around this topic and also focus on current efforts in relation to this topic in EU through COST Action  TU 1406 focused on standardization of maintenance of road bridges.

CHAIR: Prof. Vikram Pakrashi

Topic 4

Role of BMS in decision making within government departments.
Show More...

This Session covers the experience of various government bodies which are on the learning curve of the making Indian Bridge Management system (Or any new BMS) work as a decision making tool. How BMS assists in planning and statistical data mining and can provide a important tool to government department. The session aims to bring together academics, and government department officials from world over to deliberate on the various decision making capabilities of Bridge Management Systems. Under the Chair of Sitaram Sagi Raju the session will bring the network of various government departments from State PWD, Various Urban planners, Border Roads, Ministry of Road, Transport and Highways from India and also from South Asian countries.

CHAIR: Mr. Sitharam Raju Sagi

Topic 5

Network Level decision making in relation to heavy vehicle access and permitted weights. OD/ OWC movement monitoring.
Show More...

Over dimension movements and Over weight consignment movement poses a challenge the world over. Many countries have evolved many regulatory protocol to enable such movement possible without compromising on the safety of the bridge structure. Collapse of bridge during such movement is not very common but have occurred in the past. The session aims to bring together academics, and government department officials from world over to deliberate on the various decision making and regulatory protocols for OWC/ ODC movement within the gamut of Bridge Management Systems. Under the Chair of Alok Bhowmik the session will bring the network of various government departments from India and also from South Asian countries to discuss the regulatory mechanism best suited for such movement.

CHAIR: Mr. Alok Bhowmick

Topic 6

Performance assessment of existing bridges.
Show More...

Assessment of existing bridges is a real life challenge when sufficient historical data and design data is not available. Assessment and monitoring concepts for bridges is important for the intervention planning (e.g., maintenance, repair, rehabilitation, replacement) for bridges. Nevertheless, there is still a strong demand for the development and efficient use of novel techniques for monitoring and assessment of bridges. Such innovations in techniques result in cost optimization. The session aims to bring together academics, practitioners and researchers to deliberate on the newer model or modification to the present available techniques  with respect to Bridge Management Systems. Under the Chair of Sachin Joshi the session is expected to be very interesting and informative. His quest for new technique shall propel the session.

CHAIR: Mr. Sachin Joshi

Topic 7

Quality Control needs for inventory/inspection & performance data of bridges.
Show More...

Bridge maintenance and management without quality control and audits on the performance are likely to result in lower efficiency. For efficient operation of Bridge Management Systems, it is important to have a appropriate operational guidelines, standardizations and protocols for maximum benefit. The requirements and challenges within a BMS and between different BMS (which may interact with each other) can be varied and the challenge lies in addressing such variations when designing, changing or implementing standardization guidelines. The Chair of this session Prof. Vikram Prakashi intends to create a discussion around this topic and focus on initiatives undertaken by various regulatory bodies which provide code-based, institutional or other normative framework to various aspects of BMS. Prof. Pakrashi also intends to focus on current activities on this topic in EU through COST Action  TU1406 , as the leader of Working Group 5 (WG5) on Drafting of Guidelines and Recommendations.

CHAIR: Prof. Vikram Pakrashi

Topic 8

Modelling and Analysis of bridge structure with defects.
Show More...

Innovation in designs also reflect on our capabilities to analyse the old bridge structure. None other than Chair Atul Bhobe is more capable to dwell on this topic due to the vast experience from the design aspects of bridges and the experience arising from his involvement in BMS for the past many years. This session will deal with various Computational nonlinear analysis methods which are usually required to realistically predict the serviceability and ultimate structural behaviour of bridge structures. For reliability and safety evaluations, these methods must allow a proper modelling of the unavoidable uncertainty related to the geometrical and mechanical parameters of the structural problem when defects exists. 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.

CHAIR: Mr. Atul Bhobhe

Topic 9

Climate Changes and Extreme events- How to address them in BMS and Quality Control.
Show More...

Extreme weather events, High impact hurricanes, tropical storms of severe intensity, prolonged intense temperatures, are all occurrences which have been upcoming with frequent regularity. Recent events in Mumbai, Chennai, Caribbean islands, Florida etc are mute examples of how weather is playing havoc with infrastructure. Such events occur the world over and Bridge Engineers will have to prepare themselves for the impact and effect of such repeated occurrences.
In the short term the frequency of such occurrences need to be redefined and in long term proper solutions for surge in water level, high/ low temperature exposure, flash floods, landslides, snow avalanches, etc are causing damage to bridges and need solutions for event related damages.
Bridge Management systems will have to cater to change in frequency and severity of such occurrences and then evaluate the performance of the bridge structure to such frenzy. Also the various predictive models need to address these changes and surges of the nature wrath.
This session in IBMS is aimed to draw the attention of the delegates and engineers to the alarming nature of the damage that occurs and the evolution of all future predictive tools incorporating these vagaries of nature.

Topic 10

Evaluation of existing bridges where data (Historical and As-built) is not available.
Show More...

Evaluation and measurement of bridge performance is critical attribute in addressing bridge deficiencies and in providing the ability to design and build bridge remedial systems 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 behaviour. Under the chair of Prof. Nirjhar Dhang the session shall try and create a guideline for such evaluation techniques. This session aims to bring together academics, practitioners and researchers to deliberate on the newer evaluation techniques available techniques with respect to Bridge Management Systems.
