基于BIM的建筑火灾安全分析

Building fire safety analysis based on BIM

分析BIM模型和火灾模拟模型之间的异同之处,基于Autodesk Revit API二次开发技术,实现了BIM建筑模型与FDS火灾模拟模型之间的转化,应用FDS模拟公寓建筑火灾并应用人员运动模拟软件Pathfinder模拟人员疏散,最后应用Revit API将火灾模拟与人员疏散结果信息重载到BIM模型中。该方法可实现信息传递与集成,形成完整的基于BIM的建筑火灾安全应急分析路线,构建了BIM环境下建筑火灾安全与人员疏散分析技术体系。

This study analyzed the similarities and differences between BIM model and fire simulation model and realize the direct conversion of Revit building model to the FDS fire simulation model based on the application programming interface （API） of Revit. Then it used fire dynamics simulator （FDS） to simulate an apartment building fire and adopts the human movement simulator Pathfinder to simulate emergency evacuation of this building. Finally, this study input the results of fire simulation and personal evacuation simulation into BIM model based on the Revit API. The method can transfer and integrate the information, and form building fire safety evacuation path based on BIM, to structure building fire safety and evacuation system based on BIM.
