Fatigue in Metallic Bridges

8th July 2019, London

This course aims to provide an overview of fatigue in metal, and the effects this can have on bridges. The course will begin with an introduction to the types fatigue factors encountered in metals to help the learner build up their knowledge, before turning towards bridge specific fatigue issues. Inspection and repair methods will be covered, before finishing with examples and case studies looking at fatigue design and assessment for both new and existing bridges.



Introduction to fatigue in metals

Areas to be covered will include cyclic loading, stress concentrations, stress-life S-N curves, fatigue physical processes, factors affecting fatigue behaviour


Fatigue in bridges

Areas to be covered will include bridge loading, basis fatigue design/assessment codes, fatigue damage and remaining life estimation, behaviour of welded/riveted details, fatigue-critical details in bridges


Brief overview of fatigue inspection and repair methods

Fatigue inspection methods that can detect surface as well as buried cracks will be reviewed, briefly discussing their principles of application as well as their detection capabilities. Fatigue repair and strengthening methods for reducing the criticality of fatigue cracks or arresting fatigue crack propagation will also be briefly demonstrated.

Fatigue damage calculation case study examples

Detailed calculations on how to estimate fatigue damage accumulation and remaining fatigue life for the purposes of fatigue design of new bridges as well as assessment of existing bridges will be demonstrated through a number of case study examples


About the Lecturer

Dr Boulent Imam is a Senior Lecturer in Civil Engineering Structures at the Department of Civil and Environmental Engineering in the University of Surrey and Programme Director for the MSc Programme in Bridge Engineering. He has been extensively involved in the area of fatigue of bridges, carrying out research in this area collaborating 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 taking into account historical rail traffic, novel fatigue assessment methods, loading, resistance and modelling uncertainties as well as system effects. Later on, Dr imam extended his work on fatigue towards developing 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 research has expanded towards understanding the potential impacts of climate change on bridge deterioration and quantifying the resilience of bridge infrastructure against extreme events.
