Abstract(s)
Ao longo desta dissertação, é abordada a temática das obras de arte, focando-se um processo construtivo em particular, que é o Método de Lançamento Incremental. Começa-se por um enquadramento geral da temática das obras de arte, sendo feita a sua descrição, e faz-se uma síntese histórica dos materiais utilizados nas mesmas. De seguida, são apresentados os tipos de tabuleiros existentes e as tipologias estruturais das obras de arte. São mencionados ainda os processos e equipamentos construtivos que são utilizados na sua construção. É, de seguida, feita uma abordagem mais profunda ao processo construtivo alvo desta dissertação, nomeadamente questões de índole prática e de dimensionamento. É feita ainda uma aplicação prática, sendo feito um Estudo Prévio de uma solução para uma obra de arte executada com este processo construtivo. Termina-se indicando aspetos importantes na monitorização das obras de arte executadas pelo processo construtivo alvo desta dissertação, sendo ainda apresentadas as conclusões a que se chegou no final da mesma e possíveis desenvolvimentos futuros.
Throughout this dissertation, the bridge theme is approached, focusing on a specific construction process, called Incremental Launching Method. This dissertation begins by making a general approach to the theme of bridges and viaducts, referring to the historical evolution of the materials used on these structures. Next, it is specified the existing deck types and the structural types of these engineering structures. The different construction methods of these structures, and the equipment used in those methods are also mentioned. Further in, the Incremental Launching Method theme is deeply analyzed, referring the practical issues related with that, and several issues related to the design process. After that, a practical application is undertaken, presenting a case study for a structure executed with this construction method. This dissertation ends by referring some important aspects about the monitoring of structures executed with this construction method. In the end, the conclusions of this dissertation are highlighted, and some future developments are presented.
