    Introduction

    There is a large number of metallic bridges around the world that are over 100 years old. A major part of these bridges have been constructed before modern design codes were developed. These bridges have experienced large amounts of traffic throughout their long service life and may be experiencing much more intense and heavier loading than what was assumed when they were designed. Assessing the remaining life of these bridges accurately is crucial for efficient decision-making with regards to the future of such bridges.

    This course provides an overview on the fatigue behaviour of old metallic bridges. It reviews cases of fatigue damage encountered in such bridges and covers fatigue assessment procedures for the most fatigue-critical details associated with old riveted bridges. The parameters that affect the fatigue performance of riveted details are discussed. Furthermore, the course reviews advanced methods that can be utilised for improved fatigue assessment of old metallic bridges.

    The course is presented through video tutorials and multimedia content within the Moodle virtual platform, with exercises like tests and practical cases, along with live webinars.

    Course Objectives

    The aim of the course is to introduce the topic of fatigue of old metallic bridges to engineer and to demonstrate procedures for the estimation of the remaining life of such elderly bridges. The specific objectives of the course are:

    • Introduce the concept of fatigue in metallic bridges
    • Review cases of fatigue damage in old metallic bridges from around the world and provide insight into their fatigue behavior
    • Present methodologies for the estimation of remaining life of aged bridges, using traditional methods and more advanced methods of assessment.

    Boulent Imam

    Senior Lecturer at the Department of Civil & Environmental Engineering at the University of Surrey and Programme Director for the MSc Programmes in Bridge Engineering and Infrastructure Engineering & Management. His expertise lies in the area of bridge management, fatigue of structural systems, risk & reliability and climate change adaptation. Dr Imam has contributed significantly 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. He has also assisted 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 has provided valuable insight towards understanding the potential impacts of climate change on bridges and quantifying the resilience of bridge infrastructure against these impacts by developing a risk-based framework for assessing the reliability of bridges over time by considering long-term material deterioration and bridge scour as well as the consequences of failure of bridges. Over his career, Dr Imam has extensively collaborated with various European infrastructure owners and managers.

    The course is delivered online through our easy-to-use Virtual Campus platform. For this course, a variety of content is provided including:

    – eLearning materials
    – Videos
    – Interactive multimedia content
    – Live webinar classes
    – Texts and technical articles
    – Case studies
    – Assignments and evaluation exercises

    Students can download the materials and work through the course at their own pace.
    We regularly update this course to ensure the latest news and state-of-the-art developments are covered, and your knowledge of the subject is current.

    Live webinars form part of our course delivery. These allow students and tutors to go through the course materials, exchange ideas and knowledge, and solve problems together in a virtual classroom setting. Students can also make use of the platform’s forum, a meeting point to interact with tutors and other students.

    The tutoring system is managed by email. Students can email the tutor with any questions about the course and the tutor will be happy to help.

    The course is aimed at engineers and researchers at all levels, particular those involved in management of old bridge structures. Engineers not familiar with fatigue analysis of bridges that would like to get involved in this area will receive an introduction to the topic. More experienced engineers and researchers will be exposed to more advanced methods that will allow them to conduct fatigue analysis in a more reliable manner.

    Once a student finishes the course and successfully completes the assignments and evaluation tests, they are sent an accreditation certificate. The certificate is issued by Ingeoexpert to verify that the student has passed the course. It is a digital certificate that is unique and tamper-proof – it is protected by Blockchain technology. This means it is possible for anyone to check that it is an authentic, original document.

    You will be able to download the certificate in an electronic format from the Virtual Campus platform. The certificate can be forwarded by email, shared on social networks, and embedded on websites. To see an example, click here.

    Fatigue assessment of bridges is an essential part of bridge management. The course will open opportunities to people wanting to get involved in the area of bridge management and fatigue assessment of old bridge structures. It can also be beneficial to the ones wanting to receive an introduction into fatigue analysis.
