Advanced Methods for Fatigue Analysis of Bridges
Part 1- 6th July 2021 - 12:00-15:00 GMT
Part 2- 13th July 2021 - 12:00-15:00 GMT
This webinar will be split into two parts over two afternoon sessions:
Introduction to fracture mechanics analysis for fatigue cracks
The webinar will cover an introduction to the theory behind the application of fracture mechanics principles for the analysis of fatigue crack propagation in bridge details. This will be discussed within the context of bridge management decision-making. An example of the application of fracture mechanics for maintenance planning will be carried out.
Advanced Finite Element Analysis for Fatigue Design and Assessment
The webinar will cover the utilisation of advanced finite element analysis for the purposes of analysing bridge details for the purposes of fatigue assessment. Recommendations for finite element modelling will be provided. The principles of the application of the hot-spot (HS) method and the theory of critical distances (TCD) for stress concentrations in bridge details will be presented. Examples will be given for welded and riveted connections
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.
Attendance certificates are available on request after the completion of the webinar.
