Abstract(s)
O presente relatório pretende apresentar o trabalho desenvolvido durante o estágio curricular
realizado na CCAD – Serviços de Engenharia Lda., integrado no Mestrado em Engenharia Civil no ramo de
estruturas do Instituto Superior de Engenharia do Porto, tendo como objetivo a obtenção do grau de
mestre em Engenharia Civil.
O estudante teve oportunidade de ser integrado numa equipa de projeto, podendo assim
acompanhar as diversas fases de um projeto de estruturas e entrar contacto com as ferramentas de
trabalho da indústria.
Inicialmente é realizada uma breve apresentação da empresa onde se realizou o estágio curricular
e também sobre os softwares utilizados. Os conceitos teóricos e a legislação são abordadas como uma
necessidade para garantir a segurança e durabilidade dos projetos de estruturas estudados. Finalmente,
são apresentados os três casos de estudo, em que o aluno teve contacto direto.
O primeiro projeto apresentado é um reservatório de água, onde é demonstrado o raciocínio
necessário para o dimensionamento desta estrutura, em que são apresentadas algumas condicionantes
deste tipo de projetos, como as ações contabilizadas, a modelação do modelo de cálculo e o cálculo das
armaduras da laje de cobertura e da viga do reservatório.
Relativamente ao segundo e terceiro caso de estudo, estes visam o levantamento e análise
estrutural da cobertura de dois hipermercados. Nestes projetos, existe a necessidade de verificar se a
cobertura tem a resistência necessária para a alteração das cargas.
Um deles surge para a colocação de painéis fotovoltaicos, em que é possível verificar uma análise
global da cobertura, conhecendo assim qual o impacto da introdução desta nova carga na estrutura para
estados limites últimos e de serviço. Relativamente último projeto, seguindo a metodologia do anterior,
porém resulta da necessidade de alteração de unidades de circulação de ar, sendo que é feito uma análise
local nas zonas onde serão introduzidas as novas máquinas, podendo assim conhecer a resistência da
estrutura nessas zonas.
Finalmente, serão apresentadas conclusões de carácter geral sobre os projetos estudados e sobre
a importância da Engenharia de Estruturas na sociedade, bem como desenvolvimentos futuros dos temas
apresentados.
The present report aims to present the work carried out during the curricular internship at CCAD – Serviços de Engenharia Lda., integrated into the Master's in Civil Engineering with a specialization in structures at the Instituto Superior de Engenharia do Porto, with the objective of obtaining the master's degree in Civil Engineering. The student had the opportunity to be part of a project team, thus being able to follow the various phases of a structural project and get in touch with the industry's working tools. Initially, a brief presentation of the company where the curricular internship took place is provided, along with information about the software used. Theoretical concepts and legislation are addressed as a necessity to ensure the safety and durability of the studied structural projects. Finally, three case studies are presented, in which the student had direct involvement. The first project is a water reservoir, demonstrating the reasoning necessary for the design of this structure. Various constraints of such projects are discussed, including the considered actions, the modeling of the calculation model, and the calculation of the reinforcement of the roof slab and reservoir beam. Regarding the second and third case studies, they focus on the survey and structural analysis of the roofs of two hypermarkets. In these projects, it is necessary to verify if the roof has the required resistance for changes in loads. One of them arises from the installation of photovoltaic panels, providing a comprehensive analysis of the roof, understanding the impact of introducing this new load on the structure for service and ultimate limit states. As for the last project, following the methodology of the previous one, it results from the need to change air circulation units, conducting a local analysis in the areas where new machines will be introduced, thus understanding the structure's resistance in those areas. Finally, general conclusions will be presented regarding the studied projects and the importance of Structural Engineering in society, as well as future developments of the presented themes.
