  2. With analyzing of the case study and based on simulating and analyzing quantitatively, this article, considering the goal of the performance - based fire - protection design is protecting occupants from being injured and keeping buildings from being damaged, thought that fire compartmentation of a large building of saling books can be divided according to their saling malls and fire compartmentation in the saling mall can be separated by the fire - proof screen. on the evacuation design, the quantity of safety exits around these buildings and the evacuation width should be increased if possible and the safety exit number, exit width and evacuation distance can be determined according to the simulating results on smoke layer temperature and height, concentration of co2 and co, occupants evacuation time and visibility. on the means of preventing and discharging smoke, the most proper measure should be determined according to their geometrical characteristics and the natural means of discharging smoke is feasible to the large building of saling books. based on analyzing of smoke

    通過對案例分析研究，本文認為大型書城建築性能化防火設計研究的最終目的是保證人員生命安全和保證建築結構安全，在模擬計算和量化分析的基礎上，大型書城的防火分區可以將中庭連通的書城區域劃分為一個區，在書城場地內可以採用防火卷簾進行防火分區劃分;在人員疏散設計中，應盡可能利用書城賣場的空間設計較多的安全出口和增大疏散寬度，其安全出口數量、寬度和疏散距離可以根據人員安全疏散時間和煙氣溫度、沉降高度、 co2濃度、 co濃度、能見度模擬計算結果驗證確定;在防排煙方式的選擇上，應當根據建築物的幾何特點選取最適宜的措施，就大型書城建築而言，採用自然排煙的方式是可行的。
