Abstract(s)
Este trabalho tem origem no âmbito da unidade curricular DIPRE(Dissertação/Projeto/Estágio)
e tem como objetivo a realização de um projeto de estabilidade em betão armado para um
edifício habitacional localizado no Marco de Canaveses. A realização deste trabalho tem como
o objetivo aplicar, consolidar e expandir os conhecimentos adquiridos ao longo do curso de
engenharia civil com especial foco na área das estruturas.
A estrutura proposta para o edifício é composta por pilares, vigas, paredes e muros em betão
armado e utiliza como solução inovadora lajes Ferca CBX. Estas lajes aligeiradas incorporam
elementos plásticos recicláveis que permitem reduzir significativamente o peso próprio da
estrutura, sem comprometer a sua resistência ou rigidez. Entre as principais vantagens desta
solução destacam-se a redução de cargas nas fundações, a possibilidade de maiores vãos entre
apoios, e uma melhor resposta sísmica, tornando-a uma alternativa eficiente às tradicionais
lajes maciças.
Para o dimensionamento da estrutura, foi utilizado um programa de cálculo baseado em
elementos finitos, o Robot Structural Analysis, que permitiu simular o comportamento da
estrutura e validar as soluções adotadas. Como complemento para tratamento dos dados
fornecidos pelo software foram usadas folhas de cálculo em Excel existentes no mercado e
outras criadas para o efeito. Todo este trabalho foi realizado sob a orientação da Engenheira
Isabel Maria Alvim Teles, cuja experiência e acompanhamento foram fundamentais para a
consolidação dos conhecimentos aplicados.
Durante o desenvolvimento do projeto, enfrentaram-se vários desafios, nomeadamente a
compreensão do funcionamento das lajes Ferca CBX, a sua modelação correta no software, e
a necessidade de adaptar a estrutura às exigências arquitetónicas. Como o projeto de
arquitetura ainda se encontrava numa fase de estudo prévio, foi essencial realizar reuniões
com a equipa de arquitetura para ajustar o posicionamento de elementos estruturais e garantir
a compatibilidade entre forma e função.
A escolha pelas lajes Ferca CBX revelou-se acertada, permitindo reduzir o peso da estrutura,
otimizar o consumo de materiais e melhorar a eficiência global do projeto, em comparação
com soluções mais convencionais. Este trabalho representa, assim, uma oportunidade de
aplicar a teoria à prática, explorando novas soluções construtivas e contribuindo para uma
abordagem mais sustentável e eficiente no projeto de estruturas.
This work was developed within the scope of the DIPRE curricular unit (Dissertation/Project/Internship) and aims to carry out a structural stability project in reinforced concrete for a residential building located in Marco de Canaveses. The main goal of this project is to apply, consolidate, and expand the knowledge acquired throughout the Civil Engineering degree, with a particular focus on structural design. The proposed structure for the building consists of reinforced concrete columns, beams, walls, and retaining walls, and incorporates an innovative solution using Ferca CBX (Ferca CBX) slab systems. These lightweight slabs include recyclable plastic void formers that significantly reduce the self-weight of the structure without compromising its strength or stiffness. Among the main advantages of this solution are the reduction of loads on foundations, the possibility of longer spans between supports, and improved seismic performance, making it an efficient alternative to traditional solid slabs. For the structural design, a finite element-based analysis software , Robot Structural Analysis Professional, was used to simulate the behavior of the structure and validate the adopted solutions. To complement the data processing provided by the software , Excel spreadsheets— both commercially available and custom-developed for this project—were employed. The entire work was carried out under the guidance of Engineer Isabel Maria Alvim Teles, whose expertise and support were essential for the consolidation of the applied knowledge. Throughout the development of the project, several challenges were encountered, particularly in understanding the behavior of Ferca CBX slabs, accurately modeling them in the software , and adapting the structural layout to meet architectural requirements. As the architectural design was still in a preliminary study phase, it was necessary to hold meetings with the architecture team to adjust the positioning of structural elements and ensure compatibility between form and function. The choice of Ferca CBX slabs proved to be a sound decision, allowing for a reduction in structural weight, optimization of material usage, and improvement in the overall efficiency of the project when compared to more conventional solutions. This work thus represents an opportunity to bridge theory and practice, explore innovative construction solutions, and contribute to a more sustainable and efficient approach to structural design.
