Resumo: Assessing tall building oscillation is a multidisciplinary area involving knowledge from different fields of study: structural engineering, wind engineering, reliability, and even human physiology, to name a few. With the modern high strength structural materials and the latest tendencies in tall buildings construction, new structural systems have become slender and new buildings have reached greater heights as time passes. This context leads to a situation where these slender structures are sensitive to dynamic effects from wind loads and where human comfort is often the prevailing criterion for the structural design. This multidisciplinary area with slender structural systems allied to economic and environmental aspects from building construction demands a better integration between the abovementioned fields in order to achieve both human comfort and sustainable buildings (from environmental and economic points of view). This thesis aims at connecting the \"weak links\" of the Davenport\'s chain of wind loading, discussing criteria from each field involved in the oscillation assessment of a tall building: dynamic analysis, finite element modelling, wind climate modelling and comfort assessment. The axis of investigation intends to bring precision to the procedure, whilst creating a reliable set of criteria to perform a dynamic response assessment from the wind tunnel testing of tall buildings. This thesis also aims at connecting these fields of study by bringing understanding from each one of them to all the others, and at validating multidisciplinary interactions in the Davenport\'s chain. Finally, a wide dispersion of results is obtained for two different tall buildings in São Paulo. This dispersion serves to corroborate the deficient integration between these fields of study and to present a set of criteria that brings precision to the procedure, whilst allowing more economic and sustainable designs.
