O presente documento apresenta o Trabalho Final de Mestrado intitulado “Projecto de Execução de um viaduto rodoviário em betão armado e pré-esforçado”, e tem como finalidade a obtenção do grau de mestre (pós-Bolonha).
O trabalho consiste na elaboração do Projecto de Execução do viaduto rodoviário, que foi estudado anteriormente no âmbito da unidade curricular de “Pontes e Viadutos”, durante a qual foi efectuado o pré-dimensionamento do referido viaduto rodoviário, ou seja, foi elaborado o respectivo Estudo Prévio.
Tendo como base os cálculos expeditos efectuados para o Estudo Prévio, torna-se possível estabelecer um termo de comparação com os cálculos mais pormenorizados do Projecto de Execução a ser elaborado.
O presente trabalho é composto por peças escritas e peças desenhadas. As peças escritas são constituídas pela memória descritiva, memória justificativa e pelos anexos de cálculo. Já as peças desenhadas apresentam todos os pormenores necessários à boa execução da obra a ser realizada a partir deste Projecto de Execução.
O dimensionamento estrutural efectuado, respeita a regulamentação preconizada pelos principais regulamentos vigentes em Portugal, nomeadamente o “Regulamento de estruturas de betão armado e pré-esforçado” (REBAP), e “Regulamento de segurança e acções para estruturas de edifícios e pontes” (RSA). Foram também consultados outros documentos de referência, nomeadamente Eurocódigo 2 (EN 1992-1-1), Eurocódigo 7 (EN 1997-1) e o Eurocódigo 8 (EN 1998-5). Importa referir que os documentos mencionados apresentam informação mais detalhada em áreas mais específicas, tais como a geotecnia (EC7) e a actividade sísmica (EC8).
A análise estrutural de viaduto rodoviário a ser concebido, será realizada com recurso ao programa de cálculo automático SAP2000, e o tratamento dos resultados obtidos será efectuado com recurso a folhas de cálculo elaboradas em Excel.
Abstract: This present essay presents the master thesis entitled “Project Execution Phase of a road viaduct in armed and prestressed concrete”, with the finality of obtaining the master´s degree (post - Bologna). This work consists on the elaboration of the Project Execution Phase of the road viaduct, which was previously studied in the scope of the course of “Bridges and Viaducts”, during which was made the pre-dimensioning of said viaduct, in other words, the Previous Study. Based on the expeditious calculus that were made at the Previous Study, it becomes possible to establish a comparison term with the more detailed calculus that will be part of the Project Execution Phase to be elaborated. This work is composed by written and drawn pieces. The written pieces are constituted by the descriptive report, justificatory report and calculation annexes. The drawn pieces display all the necessary details to a great execution of the refered viaduct. The structural design to be made, respects the regulation that is advocated by the main by-laws legislated in Portugal, namely the regulation towards concrete and prestressed concrete structures (REBAP), and regulation towards action a safety criteria (RSA). There were also consulted other reference documents, namely EN 1992-1, EN 1997-1 and EN 1998-5. The mentioned documents present a more detailed substance in more specific areas, like geotechnics (EN 1997-1), and seismic action (EN 1998-1). The structural analysis of the road viaduct to be conceived, will be made with recourse of the automatic design software SAP2000, and the results treatment will be made with recourse of Excel sheets.
