性能化防火设计中火灾场景设计的内容和方法

为了提高火灾场景设计的合理性,介绍了火灾场景设计的内容和方法,分析了现有主要火源热释放速率模型及其优缺点.结合某商场性能化防火设计,探讨了火灾场景设计的原则和步骤,提出了火灾场景设计的完整过程应包括：起火点位置的设定、最大热释放速率的确定和火灾蔓延特性的分析等.

Contents and Approach of Fire Scenario Design in Performance-Based Fire Protection

To raise the rationality of fire scenario design, the contents and approach of fire scenario design were presented in detail from the needs of performance-based fire protection, and the advantages and disadvantages of the main models for heat release rate of fuel usually used at present were analyzed. The principles and processes of fire scenario design were discussed by taking the performance-based fire protection design of a mall in Chengdu as an example. It was pointed out that the design processes of fire scenario should include the setting of an ignition position, the determination of max heat release rate and the analysis of fire-spreading characteristics.
