PROBABILISTIC FIRE RISK ASSESSMENT OF A MID-RISE OR HIGH-RISE BUILDING WITH FIRE SAFETY EQUIPMENT SYSTEMS DAMAGED BY SEISMIC SHAKING

Feasibility Study of Use of Elevators in Fire Evacuation in a High-rise Building

In many past fires, not a few people used elevators for their evacuation, although they are told to escape by stairs in emergency. Also, it is expected that the number of people who have difficulty to use stairs in evacuation would become larger, since the proportion of aged people in the total population has been rapidly increasing recently and also accessibility of disabled people has been im...

Application of Fuzzy Neural Network to Fire Alarm System of High-rise Building

Fire alarm system is important in high-rise building. In this paper, a fire alarm system of high-rise building is designed using fuzzy system theory and neural network. The fuzzy system has superiority in inference and the neural network has superiority in learning. The design parameters of the fuzzy system can be adjusted automatically by combining the fuzzy system with the neural network. The...

Optimization of Ventilation Mode of Smoke Control System in High-rise Building Fire

In high-rise building fire, a large amount of fresh air will be pressurized into the fire floor when smoke ventilation and prevention system is used. The fresh air dilutes the smoke, but it also reduces the efficiency of mechanical exhaust. The assumption that vertical composition smoke control model (air curtain combined with pressurization and exhaust fan) is put forward. The mathematic model...

Simulation Model of Pedestrian Evacuation in High-Rise Building: Considering Group Behaviors and Real-Time Fire

Many fire evacuation models have been proposed in recent years to better simulate such as an emergency situation. However, fire has different characters in high-rise building, and is affected by all kinds of factors. Evacuation of persons in case of fire is very complex, the environment will affected it, the individual psychological quality and physical quality, real time fire and so on. The nu...
