Many researchers have explored the use of BIM technology to simplify and enhance fire and evacuation simulations in building operations.
During the design phase of integrated projects, BIM software is used to create detailed 3D conceptual models. These models incorporate comprehensive information, including building geometry, construction details, geographic location, material properties, geological conditions, and investment estimates. The main challenge lies in accurately converting BIM model data—merged with real-world conditions—into fire dynamics models. These models need to represent factors such as raw materials, fuel sources, public facilities, and financial considerations. Additionally, BIM can assist in analyzing light source illumination for various design options, helping to select appropriate lighting equipment for fire simulations.
Despite progress, significant research opportunities remain in integrating BIM with fire simulation, particularly in developing interaction techniques and secondary software enhancements. Currently, relevant published literature is limited.
In China, fire research primarily focuses on small-scale space experiments and simulations due to the hazards and control difficulties of large-scale fire testing. Evacuation studies in large spaces rely on fire drills, which lack precise scientific data. Traditional Fire Dynamics Simulator (FDS) research often targets conventional buildings, making it challenging to model innovative or unique structures. BIM addresses these challenges by offering rapid, convenient modeling while ensuring accurate and objective fire simulation outcomes.
The advantages of incorporating BIM into fire simulation include:
1) Establishing a digital, intelligent on-site management system that consolidates information from multiple platforms, enhancing fire query and command efficiency.
2) Integrating with fire dynamics and evacuation simulation software to streamline fire scene reconstruction processes.
3) Providing direct access to building and structural data critical for command and personnel investigation purposes.
