2. 1. Fire safety evaluation of multifunctional buildings - Special emphasis on antagonistic attacks and protection of sensitive areas

   Author : Martin Nilsson; Avdelningen för Brandteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multifunctional building; multipurpose building; antagonism; terrorism; design fire; fire scenario; sensitive areas; electrical appliances room; fire protection; hypoxic air venting; reduced oxygen; fire growth; building code; fire safety engineering;

   Abstract : Multifunctional buildings, often hosting societal important functions, have become increasingly more common during the last years. The combination of many functions within the same building as well as an increased exposure to antagonistic attacks create new, not previously well analyzed problems for fire safety. READ MORE

4. 2. Compartment Fire Temperature Calculations and Measurements

   Author : Alexandra Byström; Ulf Wickström; Sven Thelandersson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compartment fire temperature; heat transfer; FEM; calculation of temperature; temperature measurement; fire scenario; validation; flashover; Stålbyggnad; Steel Structures;

   Abstract : This thesis is devoted to heat transfer and fire dynamics in enclosures. It consists of a main part which summarizes and discusses the theory of heat transfer, conservation of energy, fire dynamics and specific fire scenarios that have been studied. READ MORE

5. 3. Determination of Material Properties for Fire Modelling

   Author : Ulf Göransson; Avdelningen för Brandteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material properties; Material degradation; Measurements; Fire test data; Byggnadsteknik; Building construction; Teknik; Technological sciences; Fire; Surface temperature; Mathematical modelling;

   Abstract : Fire and flame spread are very complex phenomenon to study. Several aspects need to be considered and treated. In order to be able to do a correct analysis of the flame spread phenomenon, which is necessary to be able to predict flame spread, knowledge of material properties are needed. Material properties can be obtained in different ways. READ MORE

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

   Author : Björn Sundström; Avdelningen för Brandteknik; []
   Keywords : 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;

   Abstract : 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. READ MORE

7. 5. Fire Dynamics in Multi-Room Compartment Fires

   Author : Nils Johansson; Avdelningen för Brandteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fire safety engineering; fire dynamics; multi-room compartment; numerical experiment; small-scale experiment; hot-gas-layer temperature; hot-gas-layer interface height; reproducibility;

   Abstract : Fire dynamics in multi-room compartments are explored in this thesis and new methods to study conditions in rooms adjacent to the room of fire origin are presented. Simple and transparent engineering methods can create good possibilities for understanding different complex phenomena present in fire science. READ MORE
