Wind energy is currently representing the fastest growth area of all renewables, particularly in the UK. The height of the wind turbine towers is continuously increasing to cope with the growing energy demands and engineers need to understand the possible failure mechanisms in these slender structures. Being the mostly employed form of wind-turbine support towers, metallic cylindrical shells in current design practice receive surprisingly simplistic treatment, varying between excessive conservatism and potentially serious unconservatism. This is mainly due to the widespread lack of understanding of the nonlinear phenomena that govern their behaviour.

In this project, the applicant is expected to carry out a numerical study of wind-turbine support towers with a various range of geometries and realistic imperfection forms, in order to develop a comprehensive understanding of the buckling behaviour of such structures. Experimental study employing scaled models is going to be conducted at the late stage of the project. The obtained numerical and experimental results will be used to develop codified design rules on the basis of the newly proposed ‘Reference Resistance Design’ framework, contributing towards the on-going improvement of the worldwide state-of-the-art European design rules for metal shells – EN 1993-1-6.

The research programme will address a significant gap in current fundamental knowledge in nonlinear structural mechanics and the outcomes will be transferrable to other disciplines including aerospace and mechanical engineering.
