| Abstract |
The main purpose of this study is to investigate the required fire resistance time by using performance-based fire safety design method and to predict the temperatures in post-flashover compartment fires. To examine the performance criteria of fire resistance, this study compared the equivalent time of fire exposure which was calculated by using time-equivalent formulae with the required fire resistance time determined by existing prescriptive code. Twenty-nine different type of building with a total floor area of about 4,576㎡ were surveyed in order to calculate the equivalent time of fire exposure which needs data such as the fire load energy density, ventilation factor, fire compartment materials and fire compartment geometry. A CFD was used in order to predict the temperatures in post-flashover compartment fires. All calculations were performed with STAR-CD v3.10, a commercial finite volume based CFD code. The result of numerical model using CFD has been validated using the data from full-scale experiment. |
