| To further improve fire safety management on construction sites of super high-rise buildings, this study constructs a fire risk factor index system from five dimensions: personnel, materials, equipment, environment, and management. By integrating the DEMATEL and ISM models, DEMATEL is used to transform the interdependent relationships among factors into two causal groups and to quantitatively analyze the influence relationships among system elements through indicators such as cause degree and centrality. Meanwhile, ISM is employed to classify the influencing factors into hierarchical levels and to construct a bottom-up hierarchical model, thereby more clearly revealing the hierarchical relationships among the factors and identifying key causative factors. The results show that the key factors affecting fire accidents on construction sites of super high-rise buildings are B3 (fire management capability of managerial personnel), B1 (fire safety awareness of construction personnel), and B15 (implementation of fire safety training and education). Among them, B3 (fire management capability of managerial personnel) has the highest centrality. Based on the hierarchical structure and centrality, the hierarchical structure model of fire risk causative factors can be divided into seven levels. B4 (amount of flammable materials used), B5 (storage conditions of flammable materials), and B9 (operating conditions of mechanical equipment) are located at the highest level and are identified as direct influencing factors. The model proposed in this study can provide a reference for improving fire safety management on construction sites of super high-rise buildings, thereby helping to prevent fire accidents and ensure the safety of personnel and property. |
