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

After completion of this subject the candidate should have acquired competence in the research front within selected topics of structural analysis as well as an ability to formulate and solve complex problems within this field. Knowledge: After completion of this subject the candidate should have a deep insight into uncertainty assessment of loads, load effects and resistance of marine structures subjected to wave – and wind loads and reliability analysis; including interpretation of the calculation results. Skills: After completing this course the candidate should be able to -independently develop and use methods and software and critically assess interpret the results of the analysis. -formulate research goals within this subject area. -carry out literature search and acquire knowledge from scientific articles. -carry our peer review of scientific articles within the subject area. General competence: After completion of this subject the candidate should have developed his/her ability to reason in a critical manner and utilize this ability to ensure quality control and further development of the knowledge present in the scientific literature as well as to assess where the research front lies in the relevant subject.
