Cyclic behavior of seismically non-conforming interior reinforced concrete beam...
Sabbahfar, Peyman; Melo, José; Costa, Aníbal; Varum, Humberto; Rodrigues, HugoThe cyclic behavior of reinforced concrete (RC) beam–column joints (BCJs) is still one of the critical issues in structural engineering. In this context, for the purpose of gaining a more in-depth insight about the sophisticated behavior of BCJs under cyclic loading scenarios, the current work aims to investigate the cyclic behavior of reinforced concrete beam–column joints. The cyclic behavior of four interior...
Analytical seismic fragility curves for ancient masonry buildings in Portugal
Bernado, Vasco; Costa, Alfredo Campos; Candeias, Paulo; Costa, Aníbal; Lourenço, Paulo B.The seismic performance of buildings has received special attention due to the interest in the built heritage conservation and protection of human life. The historic urban centers are dominated by old unreinforced masonry (URM) buildings, which techniques and construction materials have evolved during centuries. Given the presence of these buildings in areas of significant seismicity, extensive research is need...
Sustainable house model for earthquakes and hurricanes hazards
Torres Di Gregorio, Leandro; Costa, Aníbal; Tavares Costa, Alice; Rodrigues, Hugo; Fonseca, JorgeThe aim of this abstract is to present SHS (Simple Housing Solution) Project and its latest research results of SHS Multirisk, in line with the Sendai Framework fo Disaster Risk Reduction (2015-2030) and the Paris Agreement on Climate change (2015). The SHS Project (Simple Housing Solution) consists of a methodology for (re) construction of residences and other small buildings, in a colective effort system (com...
Application of sonic tests and modal identification in the characterization of ...
Bourgeois, Inês; Di Gregorio, Leandro Torres; Rodrigues, Hugo; Fonseca, Jorge; Tavares, Alice; Costa, AníbalThis work contemplates the application of non‐destructive techniques, sonic and environ‐ mental vibration tests, on a set of soil‐cement compressed earth blocks reinforced masonry walls, which were built in laboratory, under the project SHS‐Multirisk. The present work constitutes a comparative study that aimed at verifying the reliability of the sonic test method in masonry char‐ acterization and in testing a m...
BIM-FM integrated solution resourcing to digital techniques
Matos, Raquel; Rodrigues, Hugo; Costa, Aníbal; Rodrigues, FernandaThe facility management (FM) has been suffering significant changes since the introduction of building information modeling (BIM) in the Architecture, Engineering, Construction and Operation (AECO) sector. However, there are still challenges in BIM implementation during the building use phase, such as the difficulties related to the personalization of the maintenance management information for each case, and mo...
Convolutional neural networks and regression algorithms supporting buildings fa...
Matos, Raquel; Rodrigues, Hugo; Costa, Aníbal; Rodrigues, FernandaFacility Management is a multi-disciplinary task in which coordination is key to attaining success during the building life cycle and for which technology assumes an increasing role. This sector is demanding more available and accurate tools to optimize the management process, decrease the probability of failure, and reduce the time spent on anomaly analysis. So, the present paper presents work developed to imp...
SHS-Multirisco UFRJ-UA: solução habitacional simples para (re)construção resili...
Di Gregorio, Leandro T.; Costa, Aníbal; Rodrigues, Hugo; Fonseca, Jorge; Tavares, AliceDentre as ameaças capazes de causar desastres socionaturais, terremotos e furacões são os que mais demandam as estruturas das edificações e também os que apresentam maior imprevisibilidade. Para estas situações, está sendo desenvolvido o Projeto SHS-MULTIRISCO, que é um spin-off do Projeto Solução Habitacional Simples em parceria entre Universidade Federal do Rio de Janeiro (UFRJ) e Universidade de Aveiro (UA)....
Patrimônio rural: medidas de salvaguarda dos celeiros elevados de Portugal e do...
Tavares, Alice; Amoroso, Maria Rita; Costa, AníbalOs espigueiros ou canastros são estruturas de armazenamento de cereais representativas do Património rural, marcos no território ligados à produção agrícola. O presente estudo aborda a inventariação realizada na Região Centro de Portugal e o impacto que as alterações demográficas podem ter em relação ao objetivo de proteger e classificar estas estruturas de celeiros elevados. Realizou-se igualmente uma abordage...
Diagnóstico para uma reabilitação integrada de centros históricos: da experiênc...
Tavares, Alice; Pizzolato, Pier Paolo; Costa, AníbalA revitalização dos centros históricos com reabilitação urbana integrada tem sido um desafio no contexto internacional. A complexidade do processo reside no equilíbrio entre as medidas a promover para a preservação do Património edificado, o controlo do risco da gentrificação, a manutenção do tecido social que sustenta a preservação dos valores culturais e as funções urbanas. Este estudo aborda 10 anos de reabi...
Development of a system for cyclic shear tests on full-scale walls
Di Gregorio, Leandro; Costa, Aníbal; Rodrigues, Hugo; Fonseca, Jorge; Costa, Alice TavaresThe SHS-Multirisk Project proposes a residential model that is simultaneoulsy resistant to earthquakes and hurricanes within a specific range of magnitude to be defined in the project. This article presents the system developed to conduct full-scale cyclic shear (combined with bending) tests on walls, exploring its characteristics, the development process, the experiment execution process, and a basic analysis ...
