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

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

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

    Abstract : 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. READ MORE

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

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

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

    Abstract : 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. READ MORE

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

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

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

    Abstract : 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. READ MORE
