Back4.1.6.2.(1)

ATTRIBUTION:

Functional Statement:

F20

To support and withstand expected loads and forces.

Objective:

OS2.1

 

APPLICATION:

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.

INTENT:

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.

APPLICATION:

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

INTENT:

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.
