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.

Em paralelo, a criação de novos materiais de construção de alta resistência, aliados às últimas tendências na construção de edifícios altos, permite sistemas estruturais cada vez mais esbeltos aplicados a edifícios cada vez mais altos. Este contexto leva a uma situação em que estes sistemas estruturais são sensíveis aos efeitos dinâmicos das cargas de vento e onde o conforto humano é frequentemente o critério preponderante para o projeto estrutural. Esta área multidisciplinar, com seus sistemas estruturais esbeltos, aliada aos aspectos econômicos e ambientais da construção de edifícios altos, exige uma melhor integração entre os campos acima referidos para se alcançar conforto humano em edifícios sustentáveis (tanto do ponto de vista ambiental quanto do econômico). Esta tese tem como eixo de investigação os \"elos fracos\" da corrente de cargas de vento de Davenport e discute os critérios de cada campo envolvido na avaliação das oscilações de um edifício alto: análise dinâmica, modelagem de elementos finitos, modelagem probabilística de vento e avaliação de conforto. O eixo de investigação proposto visa a trazer precisão ao procedimento, criando um conjunto de critérios confiáveis para a avaliação da resposta dinâmica a partir de ensaios em túnel de vento de edifícios altos. Esta tese também visa a conectar estes campos de estudo, trazendo a compreensão de cada um deles para todos os outros e para validar as interações multidisciplinares na corrente de Davenport. Finalmente, uma grande dispersão de resultados é obtida para dois edifícios altos em São Paulo. Esta dispersão serve para corroborar a deficiência da integração entre estes campos de estudo e para apresentar um conjunto de critérios que traga precisão ao procedimento, permitindo, concomitantemente, projetos mais econômicos e sustentáveis.Biblioteca Digitais de Teses e Dissertações da USPMazzilli, Carlos Eduardo NigroFerrareto, Johann Andrade2017-05-05info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisapplication/pdfhttp://www.teses.usp.br/teses/disponiveis/3/3144/tde-17072017-105508/reponame:Biblioteca Digital de Teses e Dissertações da USPinstname:Universidade de São Paulo (USP)instacron:USPLiberar o conteúdo para acesso público.info:eu-repo/semantics/openAccesseng2018-07-17T16:38:18Zoai:teses.usp.br:tde-17072017-105508Biblioteca Digital de Teses e Dissertaçõeshttp://www.teses.usp.br/PUBhttp://www.teses.usp.br/cgi-bin/mtd2br.plvirginia@if.usp.br|| atendimento@aguia.usp.br||virginia@if.usp.bropendoar:27212018-07-17T16:38:18Biblioteca Digital de Teses e Dissertações da USP - Universidade de São Paulo (USP)false
