- Matrices - Book of Abstracts: II International Congress Architecture and GenderPublication . Pedrosa, Patrícia Alexandra Dias Santos ; Santos, Eliana Sousa; Matos, Maria João Pereira de ; Alvarez Lombardero, NuriaThe Second International Congress on Architecture and Gender will address the theme of Matrices. This concept has several definitions and they are all inclusive by nature. Matrices are environments where things develop, the models or patterns that shape formations, and they can also reinvent an environment. These images are suited to address the current patterns of change regarding architecture and gender.
- Teoria critica de apoio pedagógico à unidade curricular de Desenho IPublication . Sequeira, João Manuel Barbosa Meneses deO presente manual insere-se no âmbito da unidade curricular de Desenho I, leccionada no 1.º ano do Mestrado Integrado em Arquitectura da Universidade da Beira Interior. Resulta de uma prática pedagógica continuada que, ao longo dos últimos anos, tem procurado articular a formação técnica do desenho com uma reflexão crítica e sensível sobre o papel da representação na génese do projecto arquitectónico. Embora concebido como instrumento de apoio ao ensino, o seu horizonte ultrapassa o contexto estrito da unidade curricular, visando propor um contributo mais amplo para a pedagogia do desenho em arquitectura.
- Investigação em artes e arquitectura: Natureza, metodologias, validade e impactoPublication . Sequeira, João Manuel Barbosa Meneses deA discussão sobre a Investigação nas artes e na arquitectura, enquanto práticas dotadas de metodologias próprias e com potencial para serem consideradas formas válidas de produção de conhecimento, é central em muitos debates contemporâneos nas humanidades e ciências sociais. Para abordar esta hipótese, podemos dividir a discussão em três áreas principais: Da Natureza: Investigação em Artes e Arquitectura Das Metodologias: Regras Próprias Da Validade e Valor do Conhecimento Produzido
- Das Mulheres e da Arquitetura: Fragmentos, diálogos e reflexõesPublication . Pedrosa, Patrícia SantosEste livro, com autoria de Patrícia Santos Pedrosa e prefácio de Zaida Muxí Martínez, resulta do projeto de investigação “Mulheres Arquitetas em Portugal: Construção da Visibilidade” (W@ARCH.PT). A partir de fragmentos, diálogos e reflexões, a obra reúne quatro narrativas através de um olhar crítico e reflexivo sobre as mulheres e as suas histórias, contribuindo desta forma para uma narrativa maior — a da história das mulheres arquitetas em Portugal.
- Remapping Modernisms: Contemporary DebatesPublication . Zein, Ruth Verde; Pedrosa, Patrícia SantosAn International Docomomo conference in Latin America presents an opportunity to reflect on the very definition of modernity and modern architecture from diverse points of view. In the last decades of the previous century and the first decades of this one, international knowledge about 20th-century architecture has been significantly expanded, following in-site and archival research held by scholars worldwide. This recognition makes it increasingly clear how canonical history books, written decades ago by prestigious authors and being used worldwide as references to the situate Modern Architecture are outdated. Albeit very important and still very useful, these narratives are incomplete, of insufficient temporal and geographical range, and blind to the debate of gender and race issues, that are indispensable from a contemporary point of view. Yet – perhaps for lack of other options –we still rely upon them to define our current conceptual definition of “Modern Architecture”. It is an uncomfortable situation that must be questioned. It is necessary to expand our awareness, to remap, reframe, and perhaps re-date what should be defined and comprised as “Modern Architecture”. Revising the established propositions, reframing the habitual debates, and rethinking our teaching and research studies’ scope and focus is unavoidable.
- Improving the Behaviour of Green Concrete Geopolymers Using Different HEMP Preservation Conditions (Fresh and Wet)Publication . Saez-Perez, Maria Paz; Jorge Alberto, Duran-Suarez; Castro-Gomes, JoãoThis paper evaluates a type of geopolymer concrete that uses hemp fibres as a natural aggregate due to the various advantages offered by these woody materials. These advantages include ease of cultivation and processing and their use in the essential structure of concretes used for green construction purposes. The sampling study was prepared using an environmentally friendly inorganic binder, based on geopolymerization reactions (Si-Na). The improvement in the hemp aggregate using two different preservation methods (fresh and wet) was assessed. The type of conservation enables anaerobic reactions to take place in the structure of the hemp, in such a way as to modify the proportions of the organic compounds contained in the hemp and the morphology of the fibres. It also encourages the proliferation of cellulose nanofibrils (CNC), which enhance the mechanical results, improving plasticity and thixotropy. The hempcrete studied in this paper could be a good alternative material for sustainable, environmentally friendly construction, as much less CO2 is emitted during the production process in comparison with conventional concrete. Using wet-preserved hemp means that less water must be added to the mix during preparation of the concrete. This also helps reduce production costs, and by extension, the cost of the final product.
- Microstructural properties of Asian hornet nest paper-like materials: Preliminary step towards biomimicry materials for civil engineering applicationsPublication . Sedira, Naim; Pinto, Jorge; Gomes, Ana; Nepomuceno, Miguel; Pereira, SandraThis paper presents a comprehensive examination of the microstructure and mineralogy of the paper-like material found in Asian hornet nests (referred to as AHN P-LM) and the nearby tree leaves, utilising scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS) and X-ray diffraction (XRD). The analysis conducted through SEM-EDS demonstrates that AHN P-LM is primarily composed of plant fragments, with slight traces of inorganic substances (such as CaOx). The thread-like morphologies observed in the SEM analysis, which are linked to the secretion of hornets, warrant attention due to their significance in understanding the microstructure of AHN P-LM. The presence of nitrogen (N) in the EDS analysis of AHN P-LM, in contrast to its absence in analysed leaves, strongly implies that the nitrogen originates from hornet saliva. Additionally, SEM-EDS analysis revealed the impact of chemical composition variations on colour differences within AHN P-LM. Furthermore, X-ray diffraction analysis on ash samples from AHN P-LM confirmed the presence of minerals such as quartz, lime, phlogopite, and microcline. These findings about mineral composition align closely with results obtained from SEM-EDS analyses, presenting various aspects related to understanding the structure and compositional makeup of AHN P-LM. Biomimicry principles can be applied to draw inspiration from the AHN P-LM for replication in the civil engineering field, facilitating innovative solutions. Understanding hornet behaviour and nest material composition is essential. Future outlook includes utilising these materials in wood construction, 3D printing for structural components, shelters, infrastructure repair, green building, and architectural innovation.
- Caracterização mecânica do material do ninho da vespa asiáticaPublication . Sedira, Naim; Santos, Moisés; Pereira, Fábio; Santos, Cristóvão; Pereira, Sandra; Nepomuceno, Miguel; Bentes, I.; Pinto, JorgeO ninho da vespa asiática (NVA) tem despertado o interesse de vários investigadores de diversas áreas do conhecimento. Na perspetiva da construção, este ninho revela uma complexidade funcional, arquitetónica, construtiva, estrutural e material deveras interessante. Alguns trabalhos de investigação foram publicados recentemente sobre o estudo desta construção animal. De uma maneira geral, estes trabalhos debruçaram-se sobre uma visão macro das estratégias construtivas, sobre a caracterização química do material de construção e sobre a descrição da solução arquitetónica e construtiva. Este trabalho de investigação pretende dar um contributo na caracterização mecânica do material do ninho da vespa asiática. Para o efeito, foram recolhidas algumas amostras de material de um ninho de vespa asiática, foram preparados diferentes provetes, ajustadas as técnicas de ensaio e realizados ensaios de tração. Com base nos resultados experimentais, foi possível obter de forma aproximada a capacidade resistente à tração do referido material. Importa acrescentar que este material é natural, de origem celulósica e bastante heterogéneo. Pensa-se que este trabalho possa dar contributo na temática dos materiais e das construções naturais.
- Contributos para o estudo da construção de falsa cúpula em Portugal: A malhada de porcos no contexto agro-pastoril da Beira BaixaPublication . Salvado, JoãoEsta comunicação é motivada pelo desconhecimento em torno duma estrutura não habitacional destinada ao abrigo de porcos na sub-região da Beira Baixa, cuja existência é escassamente documentada pelas mais importantes publicações dedicadas ao assunto. Tendo como objetivo o seu reconhecimento no âmbito das Histórias da Arquitetura e da Construção portuguesas, a investigação traça o perfil da malhada de porcos beirã considerando o meio concreto em que progride, função, morfologia e materiais recorrentes, e tipos de cobertura. Como tal, definiram-se três estruturas num universo de meia centena de malhadas conhecidas na região, desde Castelo Branco até Penha Garcia, que foram posteriormente analisadas ‘in loco’ mediante levantamentos geométricos, fotográficos e descritivos. Como ponto de chegada, as construções erguem-se em alvenaria de granito, xisto ou mista, orientadas para o meridiano sobre jazigos minerais. São conformadas por séries de furdas organizadas numa planta em «U», rebolim, dobradeira e casa do porqueiro, apresentando na amostra observada dimensões entre 15 e 39 m de comprimento. Assinala-se nas malhadas uma morfologia preeminente em toda a região, e os telhados são de duas águas ou em falsa cúpula. Conservam-se maioritariamente isoladas na paisagem, em meio ao montado de sobro, exibindo muitas ruína iminente ou consumidas por vegetação cerrada.
- CH-Resilience Project (Cultural Heritage: Resilience of Built Heritage and Built Environment): Internationalization and Research Network within the “Universitas Montium” (UNITA) AlliancePublication . Martins, Ana M. T.; Nepomuceno, Miguel C. S.; Simão, Inês Cunha; Juan García, Natalia; Campelo-Gaínza, Carlos; Pedro Lorente, Jesús; Salvado, João Pedro Ferreira; Rodrigues, Tiago; Cabeleira, João; Amoreira, SofiaThis paper presents the research work within the international Consortium Alliance "Universitas Montium" (UNITA) according one of many UNITA’s Research Projects: the Portuguese Project CH-RESILIENCE “Cultural Heritage: Resilience of Built Heritage and Built Environment” at the University of Beira Interior (UBI) within Universitas Montium Aliance which is included in UNITA's Research & lnnovation Cartography WP4, concerning Cultural Heritage. and soon to be included in the consortium RE-UNITA (UNITA 2.0). Within this research line two international PhD cotutelle were achieved, but also two other PhD thesis are being prepared within CH-RESILIENCE. The Department of Civil Engineering and Architecture (DECA), of the University of Beira Interior (UBI), has developed, a concern regarding Built Heritage, ln fact, over the last two decades there has been a cross-interdisciplinary interest, which has allowed a transdisciplinary research, based on the Architectural Heritage, Built Heritage, thus Cultural Heritage. Dissertation themes have focused on traditional aspects of Portuguese Architecture and Traditional Building Technologies, but also doctoral Thesis and Research Projects with competitively-based contests with funding (as The ORFEUS project which was one of the highlights of this line of research). In fact, Building Culture encompasses existing buildings, monuments, and other elements of Cultural Heritage, as well as the design and construction of contemporary buildings, infrastructures, public spaces, and landscapes. The actual technical requirements are not always compatible with older buildings. Regular maintenance of these buildings may include preservation, rehabilitation, restoration, reconstruction, refurbishment, adaptation, and interpretation of existing buildings and their environment. ln fact, this research lays on the Resilience of Built and Cultural Heritage. UNITA’s Research and innovation is centred in the needs of rural and mountain territories regarding, not only Cultural Heritage, but also Renewable Energy and Circular Economy. This paper presents four case study of international research based on the UNITA’s Alliance and interconnected with CH Resilience Project: “The Art of Place”, Cotutelle (UBI -Portugal / UNIZAR-SPAIN); “The involvement of local museums with their territorial and historical environment”, Cotutelle (UNIZAR-SPAIN / UBI -Portugal); Corbelled Dome Constructions: architectural elements of a vernacular Identity in Beira Baixa (Portugal); Resilience and Sustainability: Monastic Spaces of Cistercian origins in contemporary times. Besides these four cases it is highlighted, a fifth which is the first project, within the CH Resilience research group, in collaboration with other institutions with affinity to the theme and in the borderline of UNITA Alliance. This is the ongoing PhD thesis “Theory, Design and Construction of the Bulwark Defensive System in the Minho River Valley. From the Reign of King Philip III to the End of the Seven Years' War, 1621-1763”. Consequently, this paper will bring to discussion these specific case studies and its relationship with UNITA's Alliance. This is, through Cultural heritage it will be brought to debate methods, objectives, experiences, outputs, and discussions which allow the formation of wider networks for research and resources exchange.
