Automated Evaluation of the Evacuation Performance for Large Complex Buildings Based on BIM

To evaluate the evacuation performance in building, this paper proposes a method based on BIM. First, an evacuation evaluating index system is established based on BIM. Then, the method obtained data from BIM and used improved BP neural network algorithm to evaluate and check the evacuation performance in building. The case study shows that result can be achieved to evaluate and check the evacuation performance in buildings by BIM and BP neural network. The result can be used to optimize the evacuation performance in building and provide help for the design and operation management.
