Introduction
The past 20 years, on fire, and smoke generation model development has been greatly developed, but also for the advancement of computing technology test
Model provides the input data, but also to large scale fire test can be used to verify the validity and limitations of computational models.
Fire safety design objectives is to prevent fires and reduce the size of the fire. By limiting the current fire codes generally combustible materials
Use, control fire and reduce the fire load method to prevent fires and reduce the size of the fire, while using material Reaction to fire tests
And combustion properties of materials classification method for controlling ignition performance, flame propagation, burn rate, smoke and toxic formation.
Assess the occurrence of fire, smoke generation and development is an important part of the performance-based design and assessment. This section provides
Using fire model or test methods to predict the likelihood of a building fire, fire development, smoke and fire product flow, etc.,
Building fire risk assessment specific workflow. This section should be GB/T 31540 other parts used in common.
This section for professionals engaged in fire safety engineering, including building fire staff, fire rescue personnel, fire safety standards
Norm makers, insurers, fire safety officers, standard users should fully understand the calculation method given in this section of the relevant parameters
Meaning and application conditions.
Fire Safety Engineering Guidelines
Part 2. fire, smoke generation and development
1 Scope
This section GB/T 31540 of the calculation method used to predict the occurrence of fire engineering, development and fumes generated can be used to assess
In order to reduce the chance of fire, limiting the development of fire, heat and smoke reduced accumulation of toxic combustion products as the goal of the effectiveness of fire safety measures.
This section applies to building fire safety engineering and fire risk assessment, as well as related engineering and computing applications.
