Abstract: Because of the lack of research on the topology characteristics of the BIM ( Building Information Modeling) sub-model with the high level of detail ( LOD) , it is hardly to extract the correct feature models instantaneously and control the quality of the modeling process efficiently. Taking the structural engineering information as the research object, the network describing the relationship between the sub-model of the high-LOD BIM of a bridge box girder was obtain and the two kinds of network nodes were mainly discussed. By employing the theorem of the Artificial Neural Electromagnetic Field ( ANEF) , the evolution laws of two types of nodes regarding the structural BIM sub-model as the information carrier were described, and the network node model without environment field effect was obtained. The node model could describe the features of the information space and the high-LOD modeling process. The connection weight of nodes demarcate the importance index of parameters, and the input matrix present the mathematical significance of the LOD index. The conclusion could provide the reference for further researching the topology of high LOD model, exploring the node model considering environment field effect, optimizing the feature information extraction scheme and quality control method of the BIM model.
