And, all of the analysis results including building fire simulation, structure safety design, and evacuation simulation can be integrated in Autodesk Revit, establishing a framework of IFC- and FDS-based information sharing for building fire safety analysis successfully. The BIM model restoring fire simulation results can support other performance-based design of building, such as structural fire-resistant design and evacuation design. And, both geometrical building information and sematic information can be shared by this approach through the transformation of coordinate systems, outer database, and IFC file extension. In this paper, a quick and accurate approach for information sharing for building fire safety analysis between mainstream BIM applications and widely used fire simulation software has been successfully implemented, based on Industry Foundation Classes (IFC) and Fire Dynamics Simulator (FDS). Although nowadays building information modeling (BIM) has become a buzzword in the Architecture, Engineering, and Construction (AEC) field to facilitate information integration and interoperability, data sharing and exchange are still weak in the traditional interoperability between BIM applications and fire simulation software, since the data schema of them are totally different. However, the fire modeling practices are often highly time-consuming and cost-intensive especially for building geometry information which does limit the further implementation of building fire safety analysis. Therefore, evacuation simulation has been done separately from each exit and evaluated with all FDS results.Abstract : With the development of computer processors, vast numerical simulation tools are widely used by fire engineers to determine the spread of fire and smoke. On the other hand, depending on the fire source and smoke movement, sometimes occupants cannot use all exits. According to comparative results, the combination of scenarios that forced smoke evacuation by fan and evacuation of occupants from all exits at the basement of the building has the lowest FED value. FED results were evaluated for poisoning risk of occupants. While occupants move through changing CO, CO 2, and O 2 concentrations, Fractional Effective Dose (FED) was gathered to obtain results from both simulations.
Fire dynamic simulations (FDS) have been done for natural and forced smoke evacuation with different scenarios at the same time, evacuation simulations have also been done for various scenarios for different exits at the building.
In this study spread of smoke from a possible fire in a University building and the evacuation time of occupants were simulated.
