Determination of Fire Spread Hazardous Buildings in Village Building Complex based on Node Deletion Method
The low-intervention building renovation measures based on fire spread analysis are meaningful for fire spread prevention and control of the village building complex. By determining the fire spread paths among buildings, the adjacency matrix and spread matrix of the fire spread network of the building complex are first established to determine the fire spread risk, and further, the node deletion method is adopted to determine the fire spread risk reduction rate of the building complex after retrofitting different buildings. Then the priority sequence of building retrofitting is analyzed and the dangerous buildings are identified. Finally, the method is applied to determine the fire spread risk of buildings in a stilt-style village complex in Yunnan. The results show that the presented method can effectively identify the hazardous buildings which have a great impact on fire spread in the complex, and the fire spread risk of the complex can be reduced considerably when only a small number of buildings are renovated.
