The use of composite concrete filled hollow columns has increased in the last decades. This type of column has several advantages, such as the exemption of the use of forms, a higher load bearing capacity and the prospect use of smaller cross sections. Although it has a good behaviour in fire situation, the use of slender columns, mainly in tall bu...
As alvenarias têm sido usadas ao longo dos séculos em paredes estruturais ou simples de compartimentação. Nos últimos 50 anos, houve algumas investigações para avaliar a resistência ao fogo de paredes de alvenaria de diversos materiais, sendo um deles o
concreto. Em 1970, Byrne [1] realizou 14 ensaios de resistência ao fogo em paredes estruturais d...
The construction in masonry is one of the oldest ways of construction. However, the knowledge regarding its structural behavior is still not well consolidated, especially regarding extreme conditions, such as fire. Although the few available studies regarding structural masonry under fire conditions show some promising results, still the available...
This paper presents the results of an experimental investigation on the fire behaviour of restrained composite columns made with square concrete filled double-skin and double-tube hollow sections. In the fire resistance tests the columns have been tested for different parameters that may influence their behavior, as for example the type of cross-se...
Nos últimos anos, o mundo tem observado alguns dos maiores incêndios florestais em termos de dimensão, número de operacionais e meios de socorro necessários no combate, levando, muitas vezes, a perdas patrimoniais e humanas. Os Grandes Incêndios Florestais (GIF) de 2017 em Portugal, pelo seu grau de destruição na floresta, habitações e indústrias e...
External walls are part of the construction system where new solutions appear every day. These systems are usually built with new materials that offer greater thermal resistance but with poor fire behaviour. This fire behaviour can be evaluated in large-scale tests, such as the ones prescribed at BS 8414-1, LEPIR II or ISO-13785-1 standards, that c...
The behaviour of building external wall systems in fire is very important on the assessing the building’s resilience. Large-scale fire tests, simulating urban fire scenarios, wherein a fire initiates inside a building and extends outward through the windows or vents are usually carried out with this purpose. However, the influence of external fires...
Os grandes incêndios florestais registados nos últimos anos em Portugal evidenciaram a vulnerabilidade dos aglomerados urbanos e das zonas industriais que possuem florestas na sua envolvente. Os incêndios de 2017 tiveram um enorme impacto com uma elevada perda de vidas humanas, mas também de infraestruturas, nomeadamente nas zonas industriais. Nest...
This paper presents a numerical model for analyzing the fire behavior of composite steel and concrete end-plate joints after earthquake. The model was developed and validated with experimental results. The obtained moment-rotation results showed that cyclic loading damage affects the performance of the joint in case of fire.
In Portugal, forest fuel management (FFM) around buildings is mandatory and regulated by Decree-Law. However, regarding the Portuguese Building Fire Safety Regulation, there are no specific provisions for applying safety measures to mitigate forest fire effects on buildings in the wildland-urban interface (WUI). Therefore, for evaluating the influe...
O incêndio representa um dos eventos mais danosos à vida e à natureza, podendo provocar tanto perda de vidas humanas, de fauna e flora nas florestas, e destruição do patrimônio e sítios ambientais e/ou arqueológicos. Os incêndios florestais, comuns em diversas partes do mundo, quando se aproximam das zonas urbanas são denominados incêndios de Inter...
A ocorrência de um incêndio, cuja origem pode ser acidental ou intencional, causa danos irreparáveis. No sentido de mitigar ou reduzir seus efeitos devastadores faz-se necessário implementar, para todo o tipo de edificação, a segurança contra incêndio, de forma a evitar perdas humanas e econômicas. Para isso, vários aspectos devem ser levados em co...
Countries like Australia, France, Greece, Italy, Portugal, Spain, and US are known for their devastating forest fire seasons, where housing and industrial buildings were subject to fire damage or destruction. To address this problem, researchers in some of these countries conducted several investigations on how forest fires affected housing buildin...
Facades are essential components of buildings that contribute to their aesthetic and functional appearance, but they can also play a significant role in spreading fires, as evidenced by the Grenfell Tower tragedy. To enhance building fire resilience, predicting fire behaviour on facade cladding systems is a critical role. Several studies have used...
Mediterranean regions are characterised by areas where wildland vegetation intermingles with human settlements and industrial facilities, called wildland-urban interfaces (WUI) and wildland industrial interfaces (WII), respectively.
Moreover, their climate conditions are prone to fire ignition and propagation in very flammable vegetation during spe...
The fire resistance of composite steel and concrete double-tube and double-skin square cross-section columns has been previously evaluated through experimental tests carried out at the University of Coimbra. The results of these experimental tests were used to calibrate a finite element numerical model. This numerical model allowed a parametric stu...
The InduForestFire project seeks mitigation solutions to avoid damage caused by large fires in industrial areas through scientific studies that explore the phenomena associated with these damages. For this, the project involves two approaches of very different nature, but complementary. The first is a forest-based approach, aimed at understanding f...
Modern facade walls, especially in high-rise buildings, have become high-performance
construction systems designed by advanced engineering [1] to improve the building’s thermal insulation and acoustic performance. Although concerns about performance have evolved, the facade performance against fires is still lacking [3]. Fire propagation on facades...
Os incêndios florestais com grande complexidade e potencial destrutivo são uma realidade que se agravou nas últimas décadas. Estes eventos tem uma recorrência histórica, mas tem-se verificado uma tendência crescente na sua regularidade e impactos na interface urbano florestal (IUF), com especial destaque para a perda de vidas humanas e para a destr...
A previsão do comportamento ao fogo dos sistemas de paredes de fachada têm se caracterizado como um desafio mundial para a segurança contra incêndio. Destaca-se que nas últimas três décadas o número de ocorrências de incêndio em fachadas cresceu em quase cinco vezes, segundo Bonner e Rein [1]. Ainda, tais dados apontam uma tendência crescente das o...
A previsão do comportamento ao fogo em fachadas é de grande importância para a resiliência do edifício contra a ação do incêndio. Diversos trabalhos têm utilizado o software FDS – Fire Dynamics Simulator [1] para o estudo da dinâmica do incêndio e seus efeitos. Foram desenvolvidas análises numérico-experimentais utilizando as normas BS-8414-1[2,3,4...
A resistência ao fogo de pilares mistos com secção quadrada de duplo-tubo (DT) e dupla-pele (DS) tem sido objeto de avaliação através de ensaios experimentais, como os desenvolvidos na Universidade de Coimbra [1]. Contudo, estes ensaios exigem muito tempo de preparação, tendo associados custos muito elevados [2]. Por forma a desenvolver um novo mét...
Nos últimos anos, a utilização de elementos mistos de aço e betão tornou-se cada vez mais popular, em particular as colunas mistas de perfil tubular de aço preenchidas com betão. A dispensa de cofragens, maior capacidade resistente axial e as reduzidas dimensões da secção transversal são algumas das razões para o sucesso deste tipo de coluna. Contu...
Forest fires have affected the Wildland-Urban Interface (WUI) in the last years with greater violence, causing damage to houses, industrial and commercial buildings. Businesses face the same fire hazard as houses but with a much greater potential due to labor interruption, job losses, and tax revenue impacts. In Canada, forest fires affected oilsan...
Nowadays with disorderly urban growth into forested areas and climate changes becoming more pronounced, the number of buildings affected by forest fires is increasing. Forest fires are becoming more destructive and socially threatening. However, it is irrefutable that the probability of a forest fire to reach a structure is dramatically reduced by...
Masonry is one of the oldest and most traditional materials in building construction. Nevertheless, the knowledge on the structural fire behaviour of masonry elements is not yet well consolidated. The literature on the load-bearing capacity of masonry walls in case of fire showed an enhanced performance of these elements, however the lack of normat...
As alvenarias ocupam o seu lugar na história da humanidade há vários séculos e são usadas para a construção de edifícios, monumentos e obras de arte. Estas são compostas por unidades de alvenaria que são ligadas entre si com argamassa.
