Data reconstruction leverages one-dimensional Convolutional Neural Networks (1D...
Minh, Tran Quang; Matos, José C.; Sousa, Hélder S.; Son, Dang Ngoc; Van, Thuc Ngo; Nguyen, Huan X.; QUYEN, NGUYENSHM data collected in systems often face data loss due to transmission errors, sensor damage, or environmental impacts. Incomplete data can lead to erroneous assessments in evaluating structural safety in complex structures. Although data reconstruction has been studied, challenges are present in data reconstruction: (i) SHM data contains a large amount of noise; (ii) data structure is complex and doesn’t allow...
Wildfire preparedness: Optimal adaptation measures for strengthening road trans...
Arango, Erica; Nogal, Maria; Sousa, Hélder S.; Matos, José C.; Stewart, Mark G.This paper addresses the growing need to shift wildfire management strategies from suppression to greater preparedness and adaptation in response to increasingly frequent and intense wildfire events. Traditional approaches prioritize suppression actions, but this study emphasizes the combined role of adaptation measures and suppression efforts in enhancing resilience to wildfires. While suppression tackles imme...
Enhancing infrastructure resilience in wildfire management to face extreme even...
Arango, Erica; Jiménez, Pilar; Nogal, Maria; Sousa, Hélder S.; Stewart, Mark G.; Matos, José C.Factors such as human activity and climate change are contributing to an increase in the frequency and intensity of wildfires. This problem has challenged society’s knowledge, response capacity, and resilience, revealing its inadequacy to cope with the new wildfire regime characterized by extreme wildfire events (EWE). Policies on wildfire management mainly focus on suppression and managing emergencies, which m...
Opportunities and challenges of digital twins in structural health monitoring
Tran, Minh Quang; Sousa, Hélder S.; Nguyen, Nhung Thi Cam; Nguyen, Quyet Huu; Matos, José C.Digital twin (DT) is one of the most modern and promising technologies in realizing smart manufacturing and implementing Industry 4.0. DT offers opportunity to integrate the physical world with digital world with a seamless data source. Civil engineering industry, in general, is facing many challenges in the process of digital transformation to improve efficiency and technology to meet the current growth rate o...
Improving societal resilience through a GIS-based approach to manage road trans...
Patiño, Erica llovana Arango; Nogal, Maria; Sousa, Hélder S.; Matos, José C.; Stewart, Mark G.Climate change is causing an increase in the frequency and intensity of wildfires, demonstrating that our capacity to respond to them is insufficient. Therefore, it is necessary to reconsider wildfire management policies, practices, and decision-support tools, extending beyond emergency measures. This study presents the extension of a GIS-based methodology for fire analysis, providing decision-making support fo...
Safety assessment of brazilian concrete bridges through reliability analysis
Santos, Ademir F.; Bonatte, Maurício S.; Sousa, Hélder S.; Bittencourt, Túlio N.; Matos, José C.This paper addresses the need for accurate and objective safety assessments of bridges in Brazil taking into account the increase in traffic load and limited funding for infrastructure. In Brazil, the usual method of ensuring bridge safety involves strengthening based on design codes using deterministic analysis and partial safety factors. This method leads to an increase in the maintenance cost of the bridges....
Flanges' impact on Persian historical masonry walls: modeling safety factors
Ghamari, M.; Karimi, M. S.; Lourenço, Paulo B.; Sousa, Hélder S.This comprehensive study investigates the nuanced impact of flanges, height-to-length aspect ratios, wall thickness, and pre-compression levels on Persian historical masonry walls under uncertainty conditions. Numerical testing of 100 masonry wall specimens, varying across five lateral constraints (flanges), four height-to-length ratios, three wall thicknesses, and three pre-compression levels, was conducted. T...
Study on the model to determine riverbed scour and the influence of bridge cons...
Bento, Ana Margarida; Minh, Tran Quang; Ferradosa, Tiago; Sousa, Hélder S.; Nguyen, Huan X.; Matos, José C.River geomorphic features can dramatically change over time. It is undoubtedly the most dynamic geomorphic system that engineers have to manage in the design and maintenance of bridges. In the event of major floods, significant changes can take place within a short period of time. In contrast to rivers which are dynamic, bridges generally do not move except in accordance with planned structural deflections caus...
A systematic review of integrated frameworks for resilience and sustainability ...
Leal, Oscar Javier Urbina; Fekete, Alexander; Ramírez Eudave, Rafael; Matos, José C.; Sousa, Hélder S.; Teixeira, Elisabete RodriguesThere is a growing tendency to assess resilience and sustainability of critical infrastructures (CI), given the significant increment in high-impact natural hazard events affecting socio-economic welfare. Historically, these assessments have been conducted separately due to the independent evolution of each concept. However, recent contributions tend to integrate them. This paper provides a state-of-the-art rev...
