- Abstract
- Over the last two decades, the development within modem building technology has resulted in an overall increase of fire hazard; buildings tend towards unconventional sizes and shapes while material contents and fittings exhibit more hazardous flammability characteristics. At the same time real advances have been made in the understanding of fire phenomena and the interaction of fii with buildings. Advancement has been particularly rapid where analytical fire modeling is concerned. Today, an engineered approach to achieving fue safety often involves the use of such calculation models to predict the course of events when a fire starts in a building. It is important to be able to state with confidence how close the actual conditions are to those predicted by a model. The authorities are often asked to accept building fire safety design based on fire models without accepted statements of their predictive accuracy. Currently, work on the determination of safety factors in fire safety design based on performance is being carried out at the Department of Fire Safety Engineering, Lund University. Such work requires uncertainties in input data and modeling uncertainty to be quantified statistically. The scope of this dissertation is on the latter subject.
