As the number of tall buildings continues to grow across the country, safety concerns—especially regarding fire hazards—have become increasingly critical. Over the past two years, fire risks have emerged as a major threat in construction projects. Traditional building methods often lack detailed fire simulation capabilities, and insufficient attention from relevant authorities has contributed to numerous serious accidents, resulting in significant loss of life and property. In this article, we explore how Building Information Modeling (BIM) is applied to enhance fire simulation.
In recent years, major fires have occurred frequently, with the majority of casualties happening inside buildings. Fire safety poses a significant threat to both lives and property, especially considering the complex internal structures of modern buildings. When a fire breaks out, it can quickly lead to severe injuries and extensive damage. Therefore, ensuring effective evacuation procedures during a fire is essential.
Traditional fire evacuation drills usually depend on manual personnel verification methods, which require substantial manpower and resources. These drills often take place only after the design phase is complete, making them costly and less efficient from an economic standpoint. To overcome these challenges, BIM technology enables virtual fire simulation and evaluation during the design process, allowing fire safety standards to be addressed proactively.
Using BIM, a fire geometry model is created by setting construction layers according to specific requirements, applying accurate thicknesses and materials. Each component is assigned a fire resistance rating based on the building’s fire classification and is automatically categorized when converted into the fire model. Additionally, BIM extracts detailed parameter information for each component, including specific heat capacity, density, conductivity, thermal resistance, and thermal conductivity.
The BIM-based fire protection workflow encompasses simulations of fire smoke, temperature fields, and safe personnel evacuation. This comprehensive simulation is grounded in the fundamental principles of fire ignition, development, spread, and smoke movement within a virtual building information model. By integrating these analyses, the approach helps reduce fire prevention costs, maximizes usable building space, and significantly enhances both the economic and social value of buildings.
Furthermore, BIM provides essential guidance for optimizing fire safety and evacuation performance in large public buildings, ensuring occupants can exit safely and efficiently during emergencies.
By applying BIM models to fire simulation, we can minimize the risk of sudden fires and quickly identify the safest evacuation routes for people, as well as the best transport paths for objects and property. The use of BIM in fire simulation not only raises safety awareness among designers, constructors, and property managers but also offers a reliable tool to effectively manage and control potential risks.
