Performance-based design of building fire protection

I. fire safety engineering

with the continuous deepening of people's research on fire phenomena and their laws, the quantitative description and analysis of fire process have been realized to a certain extent, and a new engineering discipline fire safety engineering has emerged. While developing performance-based specifications, fire safety engineering is also developing rapidly. Because of its potential, complexity and applicability, fire safety engineering has been greatly developed in the fields of basic theory, methodology and practical tools. Of course, people still need to further study the fully quantitative fire safety engineering method in architectural design

fire safety engineering involves the application of engineering principles and principles, and expert judgment based on fire phenomena, fire effects, and human reactions and behaviors. Universal energy experimental machine is a kind of comprehensive function. Because there is still a lack of fully quantitative engineering method of building design fire safety, it is required to adopt a more conservative method formed by experts or engineering analysis and judgment. However, in many countries, these recognized or accepted fire engineers who can make expert judgments are few

second, performance-based design method

performance-based design method is a new building fire protection design method based on fire safety engineering. It uses the principles and methods of fire safety engineering to quantitatively predict and evaluate the fire hazard and harmfulness of buildings according to the specific situation of the structure, purpose and internal combustibles of buildings, so as to obtain the optimal fire protection design scheme, Provide the most reasonable fire protection for buildings

performance-based design uses fire science and fire safety engineering to establish design indicators and evaluate design schemes; Fire hazard analysis and fire risk assessment are used to establish the parameters required for the rebound of the hammer body when the sample is not broken in the fields from the overall goal and functional goal to the fire scene. Performance-based fire safety design is an engineering process that can define non engineering parameters such as human behavior and response in fire

III. performance-based specifications and performance-based design methods

in performance-based specifications, generally only acceptable methods that can meet the requirements of the specifications are determined, and the requirements in the building are described through policy general objectives, functional objectives and performance requirements. For example, Australia's first performance-based comprehensive building code, the Australian building code (bca96), prepared by the Australian building code board (ABCB) in December 1996, consists of four levels of systems, namely, objectives, functional descriptions, and performance requirements; Performance based design is to choose an alternative method based on performance, that is, a term describing the design process that can achieve a specified performance level. Its design method is an engineering method in design

if the electrochemical design method with the same volume and weight can only be used together with the functional specification, there must be a set of fixed general objectives, functional objectives and performance requirements required in the specification

if the performance-based specification is not used, the following seven steps will guide the analysis and design, that is, 1. Determine the project site or the specific content of the project. 2. Determine the overall objectives, functional (or loss) objectives and performance requirements of fire safety. 3. Establish performance index and design index standards. 4. Establish fire scenarios. 5. Establish design fire. 6. Propose and evaluate the design scheme. 7. Write the final report

performance-based r=......................... The factors that must be considered in the design of formula (10) include at least the following factors: 1. Fire and development. 2. Smoke spread and control. 3. Fire spread and control. 4. Fire detection and extinguishing. 5. Inform users and evacuate. 6. Alarm reception and response of fire department
