摘　　要：性能化防火设计方法的应用为我国建筑防火设计领域中的有关难题提供了较为科学合理的解决方案 ,同时也对设计者提出了更高的要求。设计者对设计过程、方法以及工具有一个比较深入全面地认识 ,是保证建筑防火设计安全合理的基本前提之一。通过对建筑防火性能化设计的火灾场景问题进行探讨 ,以求科学地认识和理解性能化防火设计方法 。The application of performance-based design method in building fire protection design brings many benefits to building industry. It creates opportunities for designers to solve many technological problems which were considered to be irresolvable using prescriptive approach under the current building code. On the other hand, it also requires the designers to have good understanding of the engineering principles and the skills to use various engineering tools in the design process.. The use of computer models has become an essential part of performance-based engineering design process. The aim of this paper is to highlight some issues relating to :model applications and particularly the determination of the fire scenarios and the related parameters for sensitivity studies. The issues of multi-cell concept and the cell number dependence are discussed through an example of zone model application to fire simulation in a large space warehouse. The paper is the first part of a series about the performance-based design approach.
