  • Avaliação Estrutural das Paredes de Alvenaria: Central Termoelétrica de Porto de Mós: Relatório Técnico
    Publication . Fernandes, Paulo Alexandre Lopes; Pereira, João Paulo Veludo Vieira; Sousa, Romain Ribeiro de; Elbashir, Douaa Adil Osman
    A presente trabalho refere-se ao estudo de Avaliação Estrutural das Paredes de Alvenaria da Central Termoelétrica de Porto de Mós no âmbito do projeto de requalificação em curso, realizado por solicitação da Câmara Municipal de Porto de Mós (CM Porto de Mós ), com o objetivo de responder às dúvidas surgidas durante a obra em curso e permitindo à Câmara Municipal ter um instrumento que assegurasse a boa execução da obra e a preservação das paredes de fachada em alvenaria originais e com valor patrimonial (e histórico). Este documento surgiu face à necessidade da CM Porto de Mós envolver neste processo uma entidade do Sistema Científico e Tecnológico Nacional (STCN), com recursos humanos qualificados e possuidores de conhecimento técnico e científico avançado na área da Caracterização e Avaliação de Estruturas e que pudessem, de forma independente, realizar um relatório que apoiasse a decisão da CM Porto de Mós e servir de orientação a todos os envolvidos na execução da obra em curso (projetistas, direção de obra, fiscalização e dono de obra). Ocorreu um incidente durante a betonagem de uma parte da estrutura junto à parede nascente em alvenaria de pedra que levantou dúvidas relativamente à capacidade destas paredes, da ligação entre as paredes de alvenaria e a nova estrutura e da estratégia mais adequada para a continuação dos trabalhos. O presente trabalho a partir de uma inspeção ao local e recolha de informação procura esclarecer estas dúvidas deixando um conjunto de recomendações para apoiar a CM Porto de Mós a tomar as decisões que melhor defendam o interesse público e a execução dos trabalhos.
  • Sustainability and Automation in Smart Constructions
    Publication . Rodrigues, Hugo; Gaspar, Florindo; Fernandes, Paulo; Mateus, Artur
    This book gathers outstanding papers presented at the Conference on Automation Innovation in Construction (CIAC-2019). In recent years, there have been significant transformations in the construction sector regarding production and the use of computers and automation to create smart and autonomous systems. At the same time, innovative construction materials and alternative technologies are crucial to overcoming the challenges currently facing the building materials industry. The book presents numerous examples of smart construction technologies, discusses the applications of new construction materials and technologies, and includes studies on recent trends in automation as applied to the construction sector.
  • Seismic precast. Seismic performance assessment of existing precast industrial buildings
    Publication . Furtado, André; Arêde, António; Rodrigues, Fernanda; Rodrigues, Hugo; Vitorino, Hugo; Varum, Humberto; Ostetto, Liana; Batalha, Nádia; Fernandes, Paulo; Sousa, Romain; Silva, Vítor
    Past seismic events exposed important fragilities in precast reinforced concrete buildings and highlight the need to undertake measures to mitigate future losses.The study presented identify potential structural and nonstructural fragilities of the Portuguese building stock and provide guidance to reduce the associated direct and indirect socio-economic impact
  • Assessment of the Seismic Behavior of a Precast Reinforced Concrete Industrial Building with the Presence of Horizontal Cladding Panels
    Publication . Ostetto, Liana; Sousa, Romain; Rodrigues, Hugo; A. L. Fernandes, Paulo
    The latest earthquakes in Europe exposed some critical problems in the connections of cladding panels in industrial precast reinforced concrete (PRC) structures. These connections did not perform as desired, causing the panels to fall, leading to significant nonstructural damage that resulted in the loss of human life and significant socio-economic impacts due to the interruption of business. Furthermore, in addition to the behavior of the cladding system itself, it is still not clear to what extent it can influence the overall seismic performance of the main structure. Making use of a simplified macroelement, the present study assesses the seismic performance of commonly employed cladding-to-structure connections, as well as the interaction of cladding panels with industrial PRC buildings. The analyses were carried out considering a PRC building representative of a Portuguese industrial park, studied with and without cladding panels. The seismic behavior of the structure was assessed considering both nonlinear static and dynamic procedures.
  • Influence of Beam-to-Column Connections in the Seismic Performance of Precast Concrete Industrial Facilities, Structural Engineering International
    Publication . Rodrigues, Rodrigo; Vitorino, Hugo; Batalha, Nádia; Sousa, Romain; Fernandes, Paulo; Varum, Humberto
    Past earthquakes have brought attention to the poor performance of precast reinforced concrete structures, especially relating to beam-to-column connections. The evaluation of different methodologies for the analysis of beam-to-column connections in industrial buildings is important. In the present work numerical analyses developed allowed the study of the effect that different story heights and connection properties have on frequencies, drifts, seismic coefficients and connection sliding. The results showed that the friction between concrete elements and the consideration of neoprene have a small impact on the drift demands in the columns and the seismic coefficients of the structures analyzed; on the other hand, the effect of steel dowel on the drift demands and seismic coefficients is significant. The comparison of models with different properties and connections allowed a better understanding of the parameters that affect the seismic behavior of precast reinforced concrete buildings the most and provide indications for building more accurate and efficient numerical models.
