Studies On The Fire Safety Classification Of A Library

With the improvement of society, the form of architectures won't be single, which puts fire control work into a hard place, and all kinds of laws, or criterions about fire work can't establish one standard to treat with this problem. As the result, giving architecture an accurate fire safety grade is significant to fire control work, fire crops' preparing, and establishment of fire laws.This dissertation starts with the model using to classify the fire safety of simple architecture, at the base of this, sets up a special model only used into library. The model is proposed by hierarchy analysis and fuzzy evaluation, for the mensurable parameters building formation and evacuation system which play an important role in the fire safety classification, use computer simulation to get their arrangement weighting, other parameters are analysed by the conventional method that is marked by experts. For every parameter there are five different grades, after ascertaining the arrangement weighting of the middling grade, use coefficient to reduce the error.In this dissertation, fire project assessment methods are studied, set up models for fire and evacuation simulations, idiographic operated items are enumerated also. Using FDS software to get the eigenvalue of temperature, EVACNET4 gains the time of evacuation. Based on the simulation results, the arrangement weighting of parameters and coefficients are confirmed, and the practical experiences got from experts are used for reference.According as the research, an assessed table used to classify the library fire safety grade is got, and very exercisable in daily fire control work.
