This webinar will give you an overview of ways to assess the safety of existing bridges beyond the Rating Factor approach of AS5100.
A recent Austroads project developed a framework based on structural reliability theory that can be used for the Australasian context. A representative set of bridge families was selected and advanced safety assessment modelling conducted to determine:
- The level of safety achieved by the historical design provisions at the time;
- The current level of safety for these bridges as part of the higher mass limit (HML) network.
The project involved a literature review and technical advances in structural reliability theory, as well as extensive modelling and assessment of a wide range of bridge types typical of Australian practice.
You will learn about:
- The benefits of probability-based bridge assessment;
- The structural reliability basis for codes of practice;
- The parameters required to conduct bridge assessments probabilistically;
- The results for a representative suite of Australian bridge families.
Join in a live Q&A with our presenters to have your questions answered.
Presented by Dr Colin Caprani, Dr Mayer M Melhem, and Professor Mark G Stewart.
Dr Colin Caprani is a Chartered Structural Engineer and Fellow of Engineers Australia (CEng, MIStructE, CPEng, NER, FIAustE) with considerable industrial and academic experience. His work specializes on the safety assessment and performance monitoring of bridges. He is a Director of the non-profit Confidential Reporting on Structural Safety – Australasia (CROSS-AUS). He has supervised many PhD and MSc students in a variety of topics related to structural safety and bridge engineering. He has received numerous awards and attracted significant research funding. He is a prominent media contributor on structural safety issues.
Dr Mayer Melhem is a Research Fellow in the Department of Civil Engineering at Monash University. His research focuses on improving the assessment of heavy vehicle access on existing bridges by adopting structural reliability methods. As a structural engineer, he has worked on multiple bridge management and assessment projects. He is the lead author on the forthcoming Austroads report ABT6111: Bridge Assessment Beyond the AS5100 Deterministic Methodology.
Professor Mark Stewart is Director of the Centre for Infrastructure Performance and Reliability at The University of Newcastle. He has authored 5 books and published more than 500 technical papers and reports. He recently helped lead the reliability-based calibration of capacity reduction factors for AS3600 and AS3700. He has over 30 years of experience in probabilistic risk and safety assessment of infrastructure systems. He currently serves on the Australian Research Council College of Experts, has attracted more than $10 million in research funding, and is Editor-in-Chief of the international journal Structural Safety.
