ATTRIBUTION:

Functional Statement:

F20

To support and withstand expected loads and forces.

Objective:

OS2.1

 

APPLICATION:

Determination of live loads due to use and occupancy on floors and roofs as specified in Sentences 4.1.5.3.(1) and 4.1.5.10.(1) for the structural design of buildings.
This applies to buildings described in Sentence 1.3.3.2.(1) of Division A and to buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9] that are required to be designed in accordance with the requirements of Part 4.

INTENT:

To limit the probability that the live load due to use and occupancy, which is used for the design of structural elements, will not take into account the most critical of the uniformly distributed specified live load, the live load resulting from the intended use or the concentrated specified live load, which could lead to structural failure, which could lead to harm to persons.
To direct Code users to Sentence 4.1.5.3.(1) for specified uniformly distributed live load due to use and occupancy, and to Sentence 4.1.5.10.(1) for specified concentrated live load due to use and occupancy.
To direct Code users to Sentence 4.1.5.1.(2) for buildings in the Low Importance Category according to Table 4.1.2.1.

APPLICATION:

Determination of live loads due to use and occupancy on floors and roofs as specified in Sentences 4.1.5.3.(1) and 4.1.5.10.(1) for the structural design of buildings.
This applies to buildings described in Sentence 1.3.3.2.(1) of Division A and to buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9] that are required to be designed in accordance with the requirements of Part 4.

INTENT:

To limit the probability that the live load due to use and occupancy, which is used for the design of structural elements, will not take into account the most critical of the uniformly distributed specified live load, the live load resulting from the intended use or the concentrated specified live load, which could lead to:
  • the excessive deformation of, or excessive stress in, structural elements, which could lead to damage to the building, or
  • the excessive deflection or excessive vibration of structural elements, which could impede the intended use and occupancy of the building.
To direct Code users to Sentence 4.1.5.3.(1) for specified uniformly distributed live load due to use and occupancy, and to Sentence 4.1.5.10.(1) for specified concentrated live load due to use and occupancy.
To direct Code users to Sentence 4.1.5.1.(2) for buildings in the Low Importance Category according to Table 4.1.2.1.

To direct Code users to Sentence 4.1.5.3.(1) for specified uniformly distributed live load due to use and occupancy, and to Sentence 4.1.5.10.(1) for specified concentrated live load due to use and occupancy.
