4.1.6.2.(7)ATTRIBUTION:
Functional Statement:
F20
To support and withstand expected loads and forces.
Objective:
OS2.1
APPLICATION:
Slope factor for the calculation of specified snow
load when used in conjunction with shape factors for increased snow loads
as given in:
- Clause 4.1.6.2.(8)(b), which applies to sloped roofs in roof valleys, and
- Clause 4.1.6.2.(8)(e), which applies to sloped roofs subject to snow sliding or meltwater draining from adjacent roofs.
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 slope factor will not
take into account the site conditions affecting the maximum expected accumulation
of snow on sloped roofs where the roof configuration prevents snow from sliding
off the roof, which could lead to structural failure, which could lead to
harm to persons.

F20
To support and withstand expected loads and forces.
F22
To limit movement under expected loads and forces.
Objective:
OP2.1, OP2.4
APPLICATION:
Slope factor for the calculation of specified snow
load when used in conjunction with shape factors for increased snow loads
as given in:
- Clause 4.1.6.2.(8)(b), which applies to sloped roofs in roof valleys, and
- Clause 4.1.6.2.(8)(e), which applies to sloped roofs subject to snow sliding or meltwater draining from adjacent roofs.
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 slope factor will not
take into account the site conditions affecting the maximum expected accumulation
of snow on sloped roofs where the roof configuration prevents snow from sliding
off the roof, which could lead to the excessive deformation of, or excessive
stress in, structural elements, which could lead to damage to the building.
