基于三维建筑空间表达,充分结合建筑防火专题语义信息,建立了面向建筑物内部空间划分与通达性分析的一体化语义描述,并结合防火部件层次的动态特征,发展面向室内火灾动态疏散过程的三维建筑信息模型,从而辅助火灾应急疏散的三维空间逃生分析。基于实验构建的三维建筑信息模型及其基于语义的动态联通网络,证明了其在室内火灾动态疏散中的特殊价值。
A VGE-based,BIM/IFC information-supported and semantic analysis oriented 3D building information model is proposed for facilitating indoor fire emergency evacuation.By taking the dynamic behavior reasoning of building components into account,the model extends the semantic classification AVGE-based,BIM/IFC information-supported and semantic analysis oriented 3D building information model is proposed for facilitating indoor fire emergency evacuation.By taking the dynamic behavior reasoning of building components into account,the model extends the semantic classification oriented to indoor fire and considers"fire compartments-building components-building entrances"as a basis of the 3D topological representation for identifying escape spaces avoiding dangerous area.Experimental analysis proves the model has a potential to provide effective support for dynamic indoor fire emergency evacuation.
