This paper investigates the application of finite element techniques to the modelling, analysis and design of thin walled shell structures of revolution. The effects of alterations in shell thickness are examined with regards to both static and dynamic effects. A method of easily generating finite element models with complex loading conditions is developed involving the writing of pre and post processors for the finite element analysis processor. This allows the variation of design parameters such as shell thickness and multiple analysis to be carried out automatically. An attempt is made to carry out an automated cost optimisation of an existing natural draft cooling tower using the tools developed in conjunction with the FE analysis package. Effects of thickness and shape variation in the response of axisymmetric shell structures are also investigated.
