RR642 - Improved generic strategies and methods for reliability-based structural integrity assessment

This report is a summary of the research undertaken during the EPSRC/HSE sponsored project entitled 'Improved generic strategies and methods for reliability-based structural integrity assessment'. Detailed findings are documented in a range of other publications, as listed in the references.

The research covers a wide range of topics including: the development of improved methods of reliability analysis which can be easily linked with standard methods of advanced structural analysis; a detailed study of the variability of fatigue crack growth in structural steels and the implications for fatigue reliability analysis; developments in the use of reliability updating techniques in relation to the prediction of fatigue failure; applications of structural system reliability analysis to the behaviour of a North Sea jacket structure; and the development of a methodology for the reliability-based fracture assessment of pipelines containing cracks.

This report and the work it describes were funded by the Health and Safety Executive (HSE). Its contents, including any opinions and/or conclusions expressed, are those of the author alone and do not necessarily reflect HSE policy.
