4.1.5.3.(1)ATTRIBUTION:
Functional Statement:
F20
To support and withstand expected loads and forces.
Objective:
OS2.1
APPLICATION:
Specified uniformly distributed live loads due to use and occupancy, and their application for the design of structural elements of buildings, where the use of an area of floor or roof is included in Table
4.1.5.3.
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 will not take into account the expected accumulation and distribution of people and objects on the floor or roof surface, including an allowance for dynamic effects due to people, and
- the live load due to use and occupancy will be less than the prescribed minimum value.
This is to limit the probability of structural
failure, which could lead to harm to persons.
ATTRIBUTION:
Functional Statement:
F20
To support and withstand expected loads and forces.
F22
To limit movement under expected loads and forces.
Objective:
OP2.1, OP2.4
APPLICATION:
Specified uniformly distributed live loads due to use and occupancy, and their application for the design of structural elements of buildings, where the use of an area of floor or roof is included in Table
4.1.5.3.
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 will not take into account the expected accumulation and distribution of people and objects on the floor or roof surface, including an allowance for dynamic effects due to people, and
- the live load due to use and occupancy will be less than the prescribed minimum value.
This is to limit the probability of:
- 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.

Functional Statement:
F22
To limit movement under expected loads and forces.

OH4
APPLICATION:
Specified uniformly distributed live loads due to use and occupancy, and their application for the design of structural elements of buildings, where the use of an area of floor or roof is included in Table
4.1.5.3.
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

INTENT:
To limit the probability that:
- the live load due to use and occupancy will not take into account the expected accumulation and distribution of people and objects on the floor or roof surface, including an allowance for dynamic effects due to people, and
- the live load due to use and occupancy will be less than the prescribed minimum value.
This is to limit the probability of the excessive
deflection or excessive vibration of structural elements, which could lead
to negative effects on the psychological well-being of persons.
