Can Class A single-fire compartments be separated by floors?

That is, if the area of a floor is exactly less than or equal to the area of a fire compartment, then the fire compartments between different floors are separated by floor slabs, and the connection between these floors can be achieved through enclosed stairwells； If there are multiple fire compartments on a single floor, firewalls must be used for separation within that floor (what is emphasized here is not that floor slabs cannot be used; rather, it means that other types of separators such as rolling shutters or water curtains are not permitted). Therefore, there is no problem with this approach~~~~~

According to your understanding: Should the specification be described as follows: Fire compartments should be separated by firewalls, floor slabs, etc.? It can’t be used. . . Facilities are separated by such partitions. Regulations are very precise in their wording, and it’s difficult to justify one’s interpretation in such cases. The Ministry of Housing and Urban-Rural Development has explicitly stated that violations of these strict requirements exist, and design firms are required to indicate the source of the rules regarding the division of floors in multi-story \"Class A factories\"; your explanation currently lacks a legal basis.

You can’t even understand what’s being said, yet you claim my arguments are invalid. I’ve explained things to you so clearly... and yet you bring up things like bolded requirements or strict rules. These days, there aren’t many people who can understand things in such a thorough manner and explain the relevant regulations so clearly; I often correct mistakes for design institutes. There aren’t many people who can explain so much, who are willing to do so, and who get it right!

You must work in civil construction, right?

It is technically feasible from a regulatory perspective to use floor slabs to separate multi-story fire compartments of Class A, but it is impossible in practice. The reasons are as follows: Fire compartmentation of the floor is required, and the area of a single floor is close to 2,000. However, for Class A workshops, multi-story structures are necessary due to process requirements that dictate material transportation from top to bottom. If the floors are used for fire compartmentation, it becomes impossible to arrange the equipment and pipelines so that they do not pass through those floors, and regulations explicitly prohibit this

Fire compartments can be divided into vertical compartments and horizontal compartments. Among them, vertical partitioning is easy to achieve – simply set up a firewall. Horizontal partitioning is difficult to achieve, as it’s hard to ensure that equipment pipelines and similar elements do not cross fire partitions

Building Code: Article 3.3.1 (bolded as a mandatory requirement); Note 1: Fire compartments shall be separated by fire walls. This sentence is simple and straightforward, so there should be no ambiguity. 1. Between fire compartments: both vertical and horizontal connections should be included entirely. 2. It should be adopted: explicitly stated, very strict. 3. Firewall separation: no other methods are used; only this one is specified. 4. Checking the explanations of the stripes at the end of the specifications as well as the accompanying atlas also reveals no mention of fire compartments being able to be separated by floor slabs. 5. In the definition of fire compartments: they can be separated by firewalls, floor slabs, and other fire separation devices. This sentence refers to the composition of fire compartments, but it cannot be used to infer that two different fire compartments can be separated by using \"firewalls, floor slabs, and other fire separation devices\". 6. If the specifications are incorrect or overly rigid, design must be carried out in accordance with those specifications; unless the specifications are revised, they cannot be implemented based on individual interpretations. 7. Typically, the zoning in civil building designs is done by dividing them based on floor levels. There must be a reason for this; could you please explain why this approach is adopted? Is there any explanation provided during the standard implementation process?

You are referring to the note in the provisions: Fire compartments should be separated by firewalls. In the definition of fire compartments, floor slabs are mentioned. We consulted the standards development team (the Fire Protection Bureau of the Ministry of Public Security), and the response was that if a floor slab can meet the fire resistance time requirements specified in the standards as well as other requirements outlined in those standards, it can be used as a fire compartment

“Can the floor slab achieve the fire resistance time required by the standards and meet other requirements specified in them? Is this in accordance with the requirements for firewalls? For example, there should be no voids within 2 meters on either side of the firewall; does this requirement also apply to the upper and lower sides of the floor slabs?
