“ A REVIEW AND BRIEF ON FIRE EVACUATION IN BUILDING”

civil Engineering

More and more high rising buildings emerged in modern cities, but emergency evacuation of tall buildings has been a worldwide difficult problem. During this project, a replacement evacuation device for a top rising building in a fire accident was proposed and studied. This device is mainly considered special spiral slide ways and shunt valves. People during this device could fast slump to the primary floor under gravity with none electrical power and physical strength, which is suitable for various emergency evacuation including mobility impaired persons. The plane simulation test has shown that a person in alternative clockwise and counterclockwise movement won't become dizzy. The evacuated people should wear a protection pad, which may prevent the slider from being injured by surface friction with the slide, and eliminate the friction coefficient difference caused by different clothes and slide surface. The calculation result show that the evacuation speed of the new device is far faster than traditional staircases. Moreover, such new evacuation device also can be used as a way of vertical transportation in high- rise building partly. People can take it from any floor to ground floor directly, which not only save time for expecting the lifts but also save the facility . The new evacuation system is of straightforward structure, easy to use, and suitable for evacuation and partly used as vertical downwards traffic, which shows light on solving world-wide difficulties in fast evacuation in high-rise building.
