Back4.1.7.1.(4)

ATTRIBUTION:

Functional Statement:

F20

To support and withstand expected loads and forces.

Objective:

OS2.1

 

APPLICATION:

Reference velocity pressure for the calculation of load due to wind to be used in the design of buildings or 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 wind pressures at the site based on available climatic data, as provided for by the reference velocity pressure in , which could lead to structural failure, which could lead to harm to persons.

ATTRIBUTION:

Functional Statement:

F20

To support and withstand expected loads and forces.

F22

To limit movement under expected loads and forces.

Objective:

OP2.1, OP2.4

 

APPLICATION:

Reference velocity pressure for the calculation of load due to wind to be used in the design of buildings or 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 wind pressures at the site based on available climatic data, as provided for by the reference velocity pressure in , 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.

APPLICATION:

Reference velocity pressure for the calculation of load due to wind to be used in the design of buildings or 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 wind pressures at the site based on available climatic data, as provided for by the reference velocity pressure in , which could lead to the excessive vibration of the building, which could lead to negative effects on the psychological well-being of persons.
