Course content

The aim is to establish methods for probabilistic modelling and analysis of structural behaviour and safety. Applications to ships, offshore platforsm, pipelines and other marine and civil engineering structures. The subject deals with: probabilistic modelling of structural components strength against brittle fracture and ductile collapse as well as fatigue. Different methods for calculating reliability of components, including FORM/SORM integration and Monte Carlo simulation methods. Systems reliability. Bayes' updating of reliability based on proof loading, inspecting etc.. Design codes based on probabilistic methods. Reliability of existing structures. Probabilistic structural risk analysis.

Learning outcome

Establish an understanding of the theoretical basis for reliability analysis of structures and its application to marine and other load carrying structures. Develop knowledge and skills to carry out computer-based structural reliability analyses.

Learning methods and activities

Mandatory exercises and a small project work.
