Introduction
Fire Safety Assessment needs to set the fire scene analysis, and by analyzing the results to determine performance-based design and test criterion set by the
Degree of compliance. Set fire scenario is the basis for selection of fire safety assessment. To enable construction works to meet the fire safety objectives, fire scene
The setting is essential.
Fire safety goals include life safety, property safety, environmental protection and the use of continuity, for each target, the available range of different
Setting fire scene to assess the reasonableness of the test design.
Set the fire scene is selected, you need to describe the assumed characteristics of fire, the fire scenario as a basis for quantification. These assumptions fire
Disaster feature called "setting fire." Needs analysis and goal setting fire fire safety engineering to adapt, and the need to generate conservative design
Program.
Fire may develop from ignition to complete the development phase, the final decay until extinguished. Throughout the development of the fire, the usually ready
Between variables to describe the change of setting fires, such as the rate of heat release and smoke generation rate.
This section provides a set of fire and set fire scene selection methods can be used to analyze the uncertainty of fire safety of construction projects, by
Set fire scene and set fire the method chosen is credible and conservative.
To set the fire scene selection and fire safety design objectives to adapt, and can explain the occurrence likelihood and potential consequences of a fire scene.
Setting fires and fire safety should be chosen to adapt the design goals, and to ensure that combustible material that is credible and stringent fire conditions.

Part 4. Setting fire scene and setting selection fire
1 Scope
GB/T 31593 in this section provides a selection set fire scene and set fire approach.
This section applies deterministic analysis of fire safety in construction projects.

3 Terms and Definitions
GB/T 5907 and GB/T 31592 and defined by the following terms and definitions apply to this document.
3.1
Setting fire designfire
Set fire to a fire scene assumed the characteristics of a quantitative description.
Note. A typical case is important fire parameters describe changes over time, such as heat release rate and the amount of toxic components to generate, while others described
Important model input data, such as fire load density.
3.2
Set fire scenario designfirescenario
A deterministic fire safety engineering analysis of the specific fire scenario adopted.
Note. Because of possible fire scenarios is very large, so it is necessary to select the most important scenes for analysis. Setting fire scene selection is set and fire safety
Total goals adaptation, and can explain the possibility and consequences of a potential fire scenario.
3.3
Fire scene firescenario
Fire on a qualitative description of the entire development process, which is described to determine the fire characteristics reflect the views and different from other fire might occur
The key event of disaster.
NOTE. To define the fire scene is usually fire, growth, fully developed and decay phases, as well as the impact of various systems and environmental conditions of fire development process.
