Appraisement Study on People Safety Evacuation in Large Scale Communal Building during Fire

摘要

Fire danger degree of large public buildings is very high, difficulty to evacuation. Designed of fire evacuation is the most important factor when the safety degree of a large scale communal building is evaluated. Based on probabilistic analysis method - Markov model to predict public building fire evacuation rational design. Taking a large public places fire safety evacuation example case study, the results showed that: Markov model can scientifically and accurately, effectively predict extreme cases limited time traffic density, and each exit door emergency escape set a minimum flow of people. To ensure that the fire occurred within the time allowed people to evacuate to a safe area provides a theoretical basis.
