  2. 1. Durability of fire exposed concrete : Experimental Studies Focusing on Sti„ffness & Transport Properties

    Author : Joakim Albrektsson; Johan Silfwerbrand; Lars Boström; Manouchehr Hassanzadeh; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete; Fire; Polypropylene fibres; Durability; Tunnel; Damage assessment; Ultrasonic pulse velocity; Water absorption; Chloride migration; DIC; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : Road and rail tunnels are important parts of the modern infrastructure. High strength concrete (HSC) is commonly used for tunnels and other civil engineering structures, since it allows high load carrying capacity and long service life. In general, Swedish road and rail tunnels should be designed for a service life of 120 years. READ MORE

  4. 2. Fire safety design of road tunnels

    Author : Jonatan Gehandler; Avdelningen för Brandteknik; []
    Keywords : HUMANIORA; HUMANITIES; Brandsäkerhet; vägtunnlar; design; Riskbedömning; Road tunnel fire safety; Fire safety engineering; design framework; risk evaluation;

    Abstract : This thesis can be described as a journey in performance-based fire safety design. Along the way questions such as what fire safety is, how it can be measured, whether we are posing the right questions, or engineer the best solutions, have arisen. READ MORE

  5. 3. Utilizing Research to Enhance Fire Service Knowledge

    Author : Stephen Kerber; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fire dynamics; fire service; fire safety engineering; firefighting; firefighter safety;

    Abstract : This thesis explores the fire service workplace through full-scale experiments. Evidence-based information has been developed to be combined with firefighter experience to improve their knowledge of fire dynamics and the cause and effect impact of their tactics on life safety, property conservation, and incident stabilization.

  6. 4. Emissions from Fires Consequences for Human Safety and the Environment

    Author : Per Blomqvist; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kontroll av utsläpp; pollution control; Miljöteknik; Environmental technology; Byggnadsteknik; Building construction; incapacitation; CFD; simulations; emissions; particles; dioxin; PAH; gases; quantitative analysis; fire effluents; chemical characterisation; large-scale experiments;

    Abstract : Accidental fires represent a risk for people from the heat and fire effluents produced. It is clear from fire statistics that it is, in fact, the toxic gases that kill and injure many fire victims. Further, there are a number of compounds that are readily produced in fires, which have important sublethal effects on humans. READ MORE

  7. 5. Polybrominated dibenzo-p-dioxins and furans : from source of emission to human exposure

    Author : Filip Bjurlid; Jessika Hagberg; Bert van Bavel; Ingrid Ericson Jogsten; Peter Haglund; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PBDD Fs; PCDD Fs; marine mammal; combustion; fire; human milk; occupational exposure;

    Abstract : Brominated flame retardants (BFRs), which are ubiquitous in modern life and the environment, are the major source for polybrominated dibenzo-p-dioxins and furans (PBDD/Fs). The knowledge about PBDD/Fs is lim-ited compared to other environmental pollutants, even though PBDD/Fs show similar toxicity as polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs) which are considered to be among the most toxic man-made substances.
