- Sustainability and Automation in Smart ConstructionsPublication . Rodrigues, Hugo; Gaspar, Florindo; Fernandes, Paulo; Mateus, ArturThis 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.
- Comportamento Sísmico de um Pavilhão Pré-Fabricado de Betão ArmadoPublication . Batalha, Nádia; Rodrigues, Hugo; Varum, Humberto; A. L. Fernandes, Paulo; Sousa, RomainOs pavilhões pré-fabricados de betão armado são muito comuns no parque industrial em Portugal, tendo mostrado um desempenho por vezes deficiente em sismos recentes tanto ao nível dos elementos estruturais como não-estruturais. Torna-se importante a sua caraterização a fim de conhecer melhor o seu comportamento sísmico. Os pavilhões industriais de um piso, com uma estrutura porticada de vigas e pilares, com ligação encastrada na base e rotulada no topo, sobre a qual vigas de secção variável são posteriormente apoiadas é a solução mais recorrente em Portugal. Nesse sentido, este trabalho aborda o comportamento sísmico de um pórtico de um edifício industrial-tipo existente, com estrutura em betão pré‐fabricado. Essa caracterização é feita através de análises estáticas não lineares (pushover) e análises dinâmicas. Os resultados obtidos são apresentados e discutidos.
- Seismic precast. Seismic performance assessment of existing precast industrial buildingsPublication . Furtado, André; Arêde, António; Rodrigues, Fernanda; Rodrigues, Hugo; Vitorino, Hugo; Varum, Humberto; Ostetto, Liana; Batalha, Nádia; Fernandes, Paulo; Sousa, Romain; Silva, VítorPast 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 PanelsPublication . Ostetto, Liana; Sousa, Romain; Rodrigues, Hugo; A. L. Fernandes, PauloThe 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.
