To support and withstand expected loads and forces.

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.

To limit the probability that the calculation of wind load
on a building will not take into account the effect of wind turbulence in
the calculation of the maximum expected wind forces on structural elements,
which could lead to structural failure, which could lead to harm to persons.

To support and withstand expected loads and forces.

To limit movement under expected loads and forces.

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.

To limit the probability that the calculation of wind load
on a building will not take into account the effect of wind turbulence in
the calculation of the maximum expected wind forces on structural elements,
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.

To limit movement under expected loads and forces.

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.

To limit the probability that the calculation of wind load
on a building will not take into account the effect of wind turbulence in
the calculation of the maximum expected wind effects on 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.

To support and withstand expected loads and forces.

Dynamic gust effect factor for the calculation of
load due to wind on *buildings* and parts of *buildings*.

To limit the probability that the calculation of wind load
used for the design will not take into account the effects of wind turbulence
and dynamic amplification, which could lead to structural failure, which could
lead to harm to persons.
