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

Sammanfattning: 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. A method for selection and evaluation of fire scenarios in multifunctional buildings has been developed. The evaluation method is based on the performance-based design approach, using scenario analysis, and accounts for specific identified problem areas for multifunctional buildings and antagonistic attacks. To aid application of the evaluation method a method to quantify fire growth rate of fire scenarios was developed and fire protection using hypoxic air venting was investigated. Finally specific research areas that need further investigation were identified.
