Whole-life Analysis of Bridges
Date & Time
Available on Demand?
The webinar will cover the frameworks that can be used for whole-life analysis of existing bridges or for the design of new ones. Bridges are key elements of the transport network. Therefore management is essential to maintain the integrity of the bridge stock and to ensure public safety, make the best use of available resources, and minimise disruption to users.
The session will focus on
1. Maintenance Planning
* An introduction to maintenance planning and the Whole-Life Cycle.
* Routine, preventative and reactive maintenance.
* Maintenance strategies and planning based on whole-life performance
2. Whole-life Analysis Principles
* Whole life cost models
* Types of whole-life costs (inspection, maintenance, repair, user, travel delay, accident, vehicle operating, failure)
3. Deterioration Modelling of bridges:
* Causes of bridge deterioration in concrete and steel bridges,
* Empirical deterioration models,
* Mechanistic Deterioration Modelling,
* Coating performance and corrosion of metallic bridges.
4. Worked example
* An example of the application of whole-life analysis on a bridge structure will be demonstrated. The focus will be on a bridge owner who wants to decide whether to continue using an existing reinforced concrete bridge or replace its deck with a new deck.
Dr Boulent Imam is an Associate Professor (Reader) at the School of Sustainability, Civil and Environmental Engineering in the University of Surrey and Programme Director for the MSc Programmes in Bridge Engineering and Infrastructure Engineering and Management.
His main area of expertise is the whole-life performance assessment of bridges. He has extensively researched in the area of fatigue of bridges with collaborations with national and European infrastructure owners and managers, such as Network Rail, Highways England, TWI. His research has contributed towards in-depth understanding of the fatigue behaviour of riveted railway bridges and developed methods for more reliable quantification of their remaining fatigue life including detailed historical rail traffic models, novel numerical fatigue assessment methods, probabilistic modelling and reliability assessment. Dr Imam’s work on fatigue also encompasses the development of fracture mechanics guidelines for the assessment of fatigue crack growth in steel bridge details towards the optimisation of inspection and maintenance planning in steel bridges.
Recently, Dr Imam’s research has expanded towards assessing the potential impacts of climate change on bridge deterioration and quantifying the resilience of bridge infrastructure against extreme events, including bridge scour and flooding. He has served as a member of prestigious international committees (IABSE, IABMAS) and within the editorial board of high-profile journals. He has delivered Keynote lectures and has participated in scientific committees of major international conferences.
Attendance certificates are available on request after the completion of the webinar.
The format of this event will be a webinar using "Zoom Webinars".
There will be opportunity to interact with the lecturer throughout the session, both though allocated Q&A sessions, or leaving text based questions throughout the presentation which the lecturer will be able to answer at convenient opportunities.
