This is precisely, the object of this thesis, the structural verification and analysis of a floating off-shore wind turbine platform type spar, supporting a 15 MW wind turbine. It will be used the software OpenFAST to compute motions, stresses and moments of the structure, and then, taking into account that the structure of the spar is made with concrete, it will be defined the post-tensioning steel and the passive steel, according to the Spanish standard for concrete structures EHE-08. It will be also made the structural analysis during the construction process, when the spar is placed in horizontal position. This will be necessary taking into account the huge dimensions of the structure. 2020-06-26 Master thesis https://hdl.handle.net/2117/334177 PRISMA-149761 eng http://creativecommons.org/licenses/by-nc-nd/3.0/es/ Open Access Attribution-NonCommercial-NoDerivs 3.0 Spain application/pdf Universitat Politècnica de Catalunya
