Abstract
![CDATA[Natural frequencies of the tripod are generally taken as the primary indicators of dynamic response, and Pile Soil Interaction (PSI) will affect the natural frequency. To simulate PSI behaviour, P-Y method and simplified method are compared in a case study of tripod of 3 MW OWT in China to define the applicable clamped length in simplified method, the results demonstrate that 6 times of diameter is suitable for simulating frequency of the tripod. The sensitivities of geometries and material properties of tripod to natural frequency are investigated using random finite element method considering uncertainties in the design variables and materials. It is highlighted that understanding relationship between design parameters and natural frequency and develop a more effective approach to regulate the design once the structures cannot meet the requirement in preliminary design.]]
