Resumen

Environmental, political, and other considerations are leading to the installation of growing numbers of wind turbines for electricity generation. The present paper concentrates on onshore installations, in which the turbine is placed at the end of a tower founded on the ground. A serious problem with the foundation or its connection with the tower entails a global failure. A worrying percentage of the towers built before 2010 is ill designed, often with obvious manifestations of the design problem. On the other hand the new designs attempt to optimise material quantities and costs while providing an adequate behaviour under the demands imposed. Principia has gathered considerable experience in both the identification and remediation of the problems experienced by older foundations and the optimisation of new designs. The problem is particularly suitable for numerical simulations with Abaqus and the paper provides the necessary concepts and methodological approach for a reliable and satisfactory solution. More specifically, the concrete geometry is meshed with solid elements. Surface elements including rebar layers are embedded. Other parts of the structure as the steel cylinder, welded studs, anchorage bars, etc. are also included. The concrete behaviour is described with the Abaqus concrete damaged plasticity model. Abaqus/Explicit is used because of the strong non-linearities, mainly caused by concrete cracking and crushing. The methodology allows assessing the suitability of the design for ultimate, serviceability and fatigue limit states.
