Analysis Of Fire Protection Strategy On Domestic Timbered Ancient Building

By introducing fire, fire science and security science, the author deeply analyzes the characteristics and dual rule of fire and discusses the developing direction of modern fire protection science. The purpose of this paper is to put up an idea of fire risk evaluation system concerning the fire situation and security status of ancient building.Based on current status research and case analyze, the author conclude the characters, cause and hidden risk of fire, and according to which, the author puts forward the concept of "Three Emphasis and Four Difficulties" and the four aspects from nature, human, electrical and environment which cause the fire. The author also clarifies the hidden fire risk of ancient building from three aspects of people, substance and environment and two sides of possibility and harm of fire disaster. Also, some special rules of seasonal, monthly, timely and locational fire disaster are specifically analyzed through data statistical research.Through analyzing the function and significance of fire risk evaluation technology for protecting ancient building, the author primarily discusses the different means of evaluation in application of ancient building and utilizes fuzzy comprehensive evaluation to estimate the probability and harm grade of fire disaster. Ultimately, the author establishes a whole structure of fire risk evaluation system of ancient building.Further more, the author discusses the utility of the evaluation system and detailed analyzes the whole project of establishing the system as well as the relevant evaluating and mathematical measure. Found on these researches, the author brings forward the critical issues in the process of establish the system and analyzes its prospect of applicability.
