基于BIM的火灾模拟与安全疏散分析

Analysis on Fire Model and Safety Evacuation based on BIM

随着国内建筑数量在不断增加,建筑发生火灾时的人员安全疏散成为重要问题。本文选用某一建筑作为研究对象,利用Revit软件建立3D模型并分别导入火灾模拟软件Pyrosim和人员疏散软件Building Exodus中,将3D模型转换为火灾模型和疏散模型,根据对火灾的具体描述在疏散软件中进行人员安全疏散分析,并将分析结果与火灾模拟时间对比,优化建筑模型以达到安全要求。将BIM建筑信息模型运用到公共建筑安全疏散中充分体现其数据化、可视化的特点,为今后人员疏散具有重要指导意义。

With the increasing number of domestic buildings,the importance of safety evacuation in case of fire in the buildings has aroused public attention. Taking a certain public building as the research subject,the author of the thesis imports the 3D model processed by Revit software into such softwares as Pyrosim and Building Exodus by which the 3D model is converted into the fire model and the evacuation model,then conducts the analysis of safety evacuation via the evacuation software according to its detailed description of the fire. The analysis results are compared with the fire in time,and the building model is optimized in order to achieve the safety requirements. The appliance of the BIM model into the practice of safety evacuation in buildings is considered as the manifestation of the data-orientation and visualization of the BIM model,and it would provide the future practice of evacuation with significant guidance
