Abstract (EN): This work addresses basic concepts regarding the wind effects on tall buildings and their subsequent wind responses. The methodology proposed in Eurocode 1 for quantification of the wind actions, is compared with the methodology still in force in the Portuguese legislation, to assess the pros and cons of each towards a more realistic building design. Using commercial software for the structural calculations, a specific study of a given tall building is performed by the actions associated with the two regulations, with the intention of comparing stress resultants and generalized displacements. A simplified method for quantifying the dynamic action on these structures is adopted, with the purpose of studying techniques for vibration control of the along-wind response in terms of displacements and accelerations. For the tall building case under study, a realistic comparison is made between the building's response under dynamic wind action with and without a TMD.
