  1. 1. Fires in Narrow Construction Cavities : Fire Dynamics and Material Fire Performance

    Författare :Karlis Livkiss; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fire; Ventilated façade; flame height; Stone wool; expanded polystyrene; Fire Dynamics Simulator FDS ;

    Sammanfattning : There have recently been devastating fire incidents related to fire spread over ventilated façades. These incidents indicate gaps in our understanding of the fire behaviour of façades. This thesis takes a bottom-up approach to investigating fire behaviour in materials and elements associated with narrow cavities in modern constructions. LÄS MER

  2. 2. Demand for Extinguishing Media in Manual Fire Fighting

    Författare :Stefan Särdqvist; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fire fighting; Fire brigade; fire suppression; extinguishing agents; extinction; Technological sciences; Teknik;

    Sammanfattning : Risk analysis and intervention planning are important in fire prevention and risk management strategies. This study has shown that it is possible to use fire safety engineering models to estimate the development of fires on a realistic scale, and the corresponding requirement for extinguishing media.

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

    Författare :Joakim Albrektsson; Johan Silfwerbrand; Lars Boström; Manouchehr Hassanzadeh; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 4. The Development of a European Fire Classification System for Building Products - Test Methods and Mathematical Modelling

    Författare :Björn Sundström; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building construction; Byggnadsteknik; Teknik; Technological sciences; Brandteknik; Fire Protection Engineering; Conflame; Cone Tools; FDS; CFD; Duhamel?s integral; Fire Growth Rate; FIGRA; Euroclass; SBI; Single Burning Item; Cone Calorimeter; Room Corner Test; fire modelling; Reaction to fire; flashover;

    Sammanfattning : The fire technical properties of products are determining factors for the initiation and growth of fires. Measurement of fire technical properties and the understanding of how they relate to real hazards are therefore important for fire safety. LÄS MER

  5. 5. Reaction to fire performance of wood and other building products

    Författare :Lazaros Tsantaridis; KTH; []
    Nyckelord :building products; charring of wood; cone calorimeter; fire retardant treated wood; fire tests; ignitability; mass loss; rate of heat release;

    Sammanfattning : The theme of this thesis is the reaction to fire performanceof wood and other building products, andparticularly thematerial fire properties time to ignition, rate of heat releaseand smoke production. These properties have been measured by asmall-scale fire test method, the Cone Calorimeter, andpresented for different types of building products. LÄS MER
