  1. 1. Temperature distribution in air tight cavities of steel framed modular buildings when exposed to fire

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser; Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Elin Bergroth; Greta Torstensson; [2019]
    Nyckelord :Cavities; fire furnace; fire test; modular building; steel; TASEF; Brandugn; brandtest; hålrum; modulbyggnader; stål; TASEF;

    Sammanfattning : A common way to construct large buildings is by assemble prefabricated modules around a load bearing steel construction. However, if a fire occurs these buildings can be subject to a rapid fire spread due to its cellular nature. LÄS MER

  2. 2. Shadow effects in open cross-sections : An analysis of steel temperatures with COMSOL Multiphysics, TASEF and Eurocode

    Master-uppsats, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Lucas Andersson; [2018]
    Nyckelord :Shadow effects; Construction; Fire; COMSOL; TASEF; EUROCODE; Steel; Thermal radiation; Separated boundary conditions;

    Sammanfattning : Steel is a material commonly used in various constructions such as high-rise buildings, sport arenas, ships etc. Steel is a versatile building material due to its isotropic characteristics, e.g. both high tensile- and compressive strength. LÄS MER

  3. 3. Determination of Thermal Conductivity of Wood Exposed to Fire based on Small Scale Laboratory Trials for Finite Element Calculations

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Johnny Chung; [2017]
    Nyckelord :Wood; Cone Calorimeter. Conductivity; Fire; Temperature; TASEF; Finite element method; Trä; Konkalorimeter; Konduktivitet; Brand; Temperatur; TASEF; Finita elementmetoden;

    Sammanfattning : This study describes an approach to determine the thermal conductivity of wood at elevated temperatures. The aim is to be able to use the developed conductivity as input in structural elements in finite element calculations. LÄS MER

  4. 4. Temperature distribution and charring penetrations in timber assemblies exposed to parametric fire curves : Comparisons between tests and TASEF predictions

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Byggkonstruktion och brand; Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Isac Andersson; Niklas Ek; [2017]
    Nyckelord :TASEF; Delamination; Timber beams; Parametric fire curves; Fire tests; Charring; Eurocode; TASEF; Delaminering; Träbalkar; Parametriska brandkurvor; Brandtester; Förkolning; Eurocode;

    Sammanfattning : Four furnace tests have been performed using two different parametric fire curves and the results are compared with computer simulations and Eurocode calculations. What differentiates the parametric fire curve from other fire curves is in particular the cooling phase, something that has proven to be hard to model for timber structures. LÄS MER
