A segunda geração dos Eurocódigos Estruturais está em conclusão e,entre eles, o Eurocódigo 9, que se aplica a estruturas de alumínio, tema importância de poder facilitar um uso estrutural mais amplo dessematerial. Neste ...
Abstract: Fires in large buildings can have tragic consequences, including the loss of human lives.
Despite the advancements in building construction and fire safety technologies, the unpredictable
nature of fires, ...

Fires in tunnels are a major concern due to the casualties they may cause. Therefore, forced
ventilation is mandatory in long tunnels, despite the significant associated costs. In shorter tunnels,
however, natural ...

Vehicle fires are a relevant emergency in tunnels. In such an event, the most dangerous hazards to tunnel passengers are the inhalation of toxic combustion products (namely, carbon monoxide - CO) and the loss of visibility ...
Abstract: The evacuation of buildings in case of fire is a sensitive issue for civil society that also
motivates the academic community to develop and study solutions to improve the efficiency of
evacuating these spaces. ...
The study of the evacuation of buildings in emergency fire situations has deserved the attention of researchers for decades, particularly regarding the real-time guiding of occupants in their way to exit the building. ...

A tunnel fire is a dangerous accident, which may lead to serious injuries and deaths. This work studies the flow of
combustion products during naturally ventilated tunnel fires, i.e., without a mechanical ventilation system. ...

Abstract. Night natural ventilation systems have been receiving increased attention in recent years because of their energy saving potential and environmental protection when used in passive instead of active cooling. A ...
Long motorway tunnels equipped with two independent unidirectional
galleries are usually provided with longitudinal ventilation. This ventilation scheme,
when applied to smoke control, can generate significant pressure ...
Neto, J.; Morais, A.J.; Gonçalves, R.; Leça Coelho, A.(Proceedings of Sixth International Congress on Information and Communication Technology, 2021-09-24)
Considering the growing volume of information and services available on the web, it has become essential to provide websites and applications with tools, such as recommender systems, capable of helping users to obtain the ...
Neto, J.; Morais, A.J.; Gonçalves, R.; Leça Coelho, A.(Proceedings of Sixth International Congress on Information and Communication Technology, 2021-09-10)
Guiding the building occupants under fire emergency to a safe place is an open research problem. Finding solutions to address the problem requires a perfect knowledge of the fire building evacuation domain. The use of ...

Abstract: Vertical air curtains are often used to separate two different zones to reduce contaminant
transfer or even to provide aerodynamic sealing from one zone to the other. In this isothermal
full-size experimental ...

Night natural ventilation systems have been receiving increased attention in recent years because of their
energy saving potential and environmental protection when used in passive instead of active cooling. A
novel system ...
Pinto, M.; Lanzinha, J. C. G.; Viegas, J.; Infante, A.; Freire, T.(International Journal of Sustainable Building Technology and Urban Development, 2021-04)
The Indoor Environment Quality study takes on a very significant challenge when analyzed, mainly, in
buildings that encompass a more sensitive and susceptible type of population, as is the case of children.
To comply with ...
Viegas, J.; Kaluzny, P.; Durand, A.; Fluchaire, L.; Franco, D.; Saldanha, C.; Morais, J.; Gil de Morais, P.; Carrasco, L.; Pinto, L.(Journal of Building Services Engineering Research and Technolog, 2020-11)
An air curtain is used to ensure an adequate separation between two compartments that is aimed torestrict, a clean one and a contaminated one. The air curtain performance is improved with the use of anair extraction from ...
