Abstract (EN): The FEM analysis and the design of the reinforced concrete foundations of a 65 m high wind-turbo generator tower, to be constructed at the wind energy farm in 'Serra do Barroso' in northern Portugal, are detailed. On such trunk-conic towers are mounted wind turbines with three 37, 5 m blades. The analysis quantifies the permanent actions as well as the variable actions due to wind on tower, on blades and on rotor - for two wind scenarios - associated with 90° and 45° wind incidences. Although the wind energy generator towers are located at the least seismic risk zone of the country, a seismic verification under standard principles of spectral modal analysis is still performed to ascertain the anticipations. The analysis is supported by efficient interactive FEM modeling software already developed, that permitted detailed description of the pressure at tower footings, settlements under such footing slabs, total tower displacements, among others. According to Eurocode EC2, as well as to Portuguese standards RSA and REBAP, the reinforced concrete foundations were designed for the stress resultants obtained for the worst design combination. © 2005 Civil-Comp Press.
