Smeared shell modelling approach for structural analysis of heritage composite structures – An application to the Cutty Sark conservation

This paper discusses the computational modelling used to simulate the structural behaviour of the historic ship Cutty Sark and her response to different load and new support conditions, various treatments and interventions as part of a major conservation programme. A novel modelling approach suitable to analyse quickly and at a global level complex heritage structures with composite shell-like nature such as the Cutty Sark is presented. This modelling approach is validated and applied to understand and analyse a number of structural assessment problems relevant to the conservation programme including plank removal procedures and the design of a new support structure.
