Back4.1.7.1.(2)

ATTRIBUTION:

Functional Statement:

F20

To support and withstand expected loads and forces.

Objective:

OS2.1

 

APPLICATION:

Method for calculating net wind load on a building as a whole using the specified wind pressures and suctions on exterior surfaces of the building determined in Sentence 4.1.7.1.(1).
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 net wind load on a building will not take into account how windward and leeward pressures or suctions on building surfaces act to produce forces in the building structure, which could lead to structural failure, which could lead to harm to persons.

Functional Statement:

F20

To support and withstand expected loads and forces.

F22

To limit movement under expected loads and forces.

OP2.1, OP2.4

 

APPLICATION:

Method for calculating net wind load on a building as a whole using the specified wind pressures and suctions on exterior surfaces of the building determined in Sentence 4.1.7.1.(1).
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 net wind load on a building will not take into account how windward and leeward pressures or suctions on building surfaces act to produce forces in the building structure, which could lead to:
  • the excessive deformation of, or excessive stress in, structural elements, which could lead to damage to the building, or
  • the excessive deflection of structural elements, which could impede the intended use and occupancy of the building.

INTENT:

To limit the probability that the calculation of net wind load on a building will not take into account how windward and leeward pressures or suctions on building surfaces act to produce forces in the building structure, which could lead to the excessive vibration or excessive deflection of the building, which could lead to negative effects on the psychological well-being of persons.
