To support and withstand expected loads and forces.

Formula or method for distributing the total lateral
seismic force, V, determined in Sentence
4.1.8.11.(2), into forces applied
at each *storey* along the height of the *building*, for 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 calculation of loads due
to earthquake will not take into account the expected distribution of the
base shear into seismic forces acting at each storey, including higher forces
induced at the top of tall buildings, 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.

Formula or method for distributing the total lateral
seismic force, V, determined in Sentence
4.1.8.11.(2), into forces applied
at each *storey* along the height of the *building*, for 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 calculation of loads due
to earthquake will not take into account the expected distribution of the
base shear into seismic forces acting at each storey, including higher forces
induced at the top of tall buildings, which could lead to:

- 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.
