ATTRIBUTION:

Functional Statement:

F20

To support and withstand expected loads and forces.

Objective:

OS2.1

 

APPLICATION:

Exposure factor for the calculation of load due to wind on buildings and parts of buildings.
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 wind load on a building will not take into account the expected maximum winds at the site based on terrain roughness, the height of the surface or part thereof above ground, and hill configuration, which could lead to structural failure, which could lead to harm to persons.
To limit the probability that the calculation of wind load used for the design will not take into account the height of the surface or part thereof and shielding provided by surrounding buildings or trees, which could lead to structural failure, which could lead to harm to persons.

F22

To limit movement under expected loads and forces.

Objective:

OP2.1, OP2.4

 

APPLICATION:

Exposure factor for the calculation of load due to wind on buildings and parts of buildings.

INTENT:

To limit the probability that the calculation of wind load on a building will not take into account the expected maximum winds at the site based on terrain roughness, the height of the surface or part thereof above ground, and hill configuration, 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 or excessive vibration of structural elements, which could impede the intended use and occupancy of the building.
