4.1.8.12.(6)ATTRIBUTION:
Functional Statement:
F20
To support and withstand expected loads and forces.
Objective:
OS2.1
APPLICATION:
Minimum value of the 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.
INTENT:
To limit the probability that the base shear used for the
design of the structure will be based on a value obtained from a model that
is more flexible than an actual structure would be, which could lead to a
base shear value that is lower than it should be, which could lead to structural
failure, which could lead to harm to persons.

To support and withstand expected loads and forces.
F22
To limit movement under expected loads and forces.

APPLICATION:

structures analyzed using a Linear Dynamic Analysis, to be used in the design
of buildings for earthquake.

INTENT:
To limit the probability that the base shear used for the
design of the structure will be based on a value obtained from a model that
is more flexible than an actual structure would be, which could lead to a
base shear value that is lower than it should be, 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.
