Plane layout and fire separation of civil buildings 4.
The new regulations have been implemented in full.
Any violation of any one of the provisions will have serious consequences.
Interpretation of the “General Code for Building Fire Protection” series Chapter 1: Fire resistance and fire resistance rating of building structures (explained in this issue) Chapter 2: General layout of buildings 1.
Fire separation of special sites 3.
However, due to limitations such as test conditions, the fire resistance performance of most structures or components in engineering is difficult to be directly determined through testing, which poses certain risks to the fire safety of building structures
.
Fire partition 2.
We will provide a comprehensive series of interpretations for everyone and pay attention to the continuous updates of the standards.
Because the fire resistance level directly determines the fire separation distance, fire compartment, safe evacuation, etc., before we make a design, we must first determine the fire resistance of the building.
Metal structures or components; 2 wooden structures or components; 3 composite structures or components; Reinforced concrete structures or components.
Article description: 5.1.4 Currently, many building structural designs have not verified or verified the fire resistance performance of building structures or components.

Joint construction Chapter 4: Building construction and decoration 1.
This chapter focuses on explaining the fire resistance rating of civil buildings, the fire resistance limit of building components, and video explanation.
In order to fully understand the requirements of the regulations, the “General Code for Building Fire Protection” series of interpretations has been launched, consisting of 7 chapters and 23 videos, focusing on the civil construction profession.

Fire lane 3.
2 Structural fire resistance rating 1 Basic principle 5.1.4 The following load-bearing structures or components in buildings should undergo fire resistance performance verification and fire protection design based on the design fire resistance limit and stress situation, Or use fire resistance tests to verify its fire resistance performance: 1.
