To support and withstand expected loads and forces.

Determination of the design base shear, Vd,
for structures analyzed using a Linear Dynamic Analysis, to be used in the
design of *buildings* for earthquake.

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 design base shear used
for the design of buildings for earthquake, as obtained from a Linear Dynamic
Analysis, will not take into account:

- the inelastic response of the structure, or
- the level of reliability appropriate for the use and occupancy.

This is to limit the probability of 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.

Determination of the design base shear, Vd,

To limit the probability that the design base shear used
for the design of buildings for earthquake, as obtained from a Linear Dynamic
Analysis, will not take into account:

- the inelastic response of the structure, or
- the level of reliability appropriate for the use and occupancy.

This is to limit the probability of:

- the excessive deformation of, or excessive stress in, the structural elements, which could lead to damage to the building, or
- the excessive deformation of, or excessive stress in, the building structure, which could lead to damage to the building, which could impede the intended use and occupancy of the building.
