Back4.1.6.2.(2)

ATTRIBUTION:

Functional Statement:

F20

To support and withstand expected loads and forces.

Objective:

OS2.1

 

APPLICATION:

Basic roof snow load factor for the calculation of specified snow load on 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 basic roof snow load factor for large roofs will not take into account the fact that, compared to snow accumulation on the ground, wind will not significantly remove snow from large roofs, which could lead to structural failure, which could lead to harm to persons.

F22

To limit movement under expected loads and forces.

OP2.1, OP2.4

 

APPLICATION:

Basic roof snow load factor for the calculation of specified snow load on 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 basic roof snow load factor for large roofs will not take into account the fact that, compared to snow accumulation on the ground, wind will not significantly remove snow from large roofs, which could lead to the excessive deformation of, or excessive stress in, structural components, which could lead to damage to the building.
