To support and withstand expected loads and forces.

Formula for calculating the specified snow load on
roofs and other *building* surfaces subject to snow accumulation.

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.

To limit the probability that the calculation of snow load
will not take into account all the factors that affect the accumulation and
distribution of snow on roofs or other building surfaces subject to snow accumulation,
which could lead to structural failure, which could lead to harm to persons.

To limit the probability that the ground snow load and associated
rain load values will not be compatible with the geographic characteristics
by directing Code users to Sentence
1.1.3.1.(1) [], which could lead to structural failure, which could lead to harm to persons.

To limit the probability that the calculation of snow load
used for the design will not take into account the level of reliability appropriate
for the use and occupancy, which could lead to structural failure, which could
lead to harm to persons.

To support and withstand expected loads and forces.

To limit movement under expected loads and forces.

Formula for calculating the specified snow load on
roofs and other *building* surfaces subject to snow accumulation.

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.

To limit the probability that the calculation of snow load
will not take into account all the factors that affect the accumulation and
distribution of snow on roofs or other building surfaces subject to snow accumulation,
which could lead to the excessive deformation of, or excessive stress in,
structural elements, which could lead to damage to the building.

To limit the probability that the ground snow load and associated
rain load values will not be compatible with the geographic characteristics
by directing Code users to Sentence
1.1.3.1.(1) [], which could lead to the excessive deformation of, or excessive stress in, structural elements, which could lead to damage to the building.

To limit the probability that the calculation of snow load
used for the design will not take into account the level of reliability appropriate
for deflection serviceability, which could lead to the excessive deformation
of, or excessive stress in, structural elements, which could lead to damage
to the building.
