Back4.1.8.12.(8)

ATTRIBUTION:

Functional Statement:

F20

To support and withstand expected loads and forces.

Objective:

OS2.1

 

APPLICATION:

Determination of the design values of elastic storey shears, storey forces, member forces and deflections whose values are obtained from 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 elastic storey shears, storey forces, member forces and deflections resulting from a Linear Dynamic Analysis will be proportioned in accordance with the design base shear, which could lead to structural failure, which could lead to harm to persons.

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:

Determination of the design values of elastic storey shears, storey forces, member forces and deflections whose values are obtained from 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 elastic storey shears, storey forces, member forces and deflections resulting from a Linear Dynamic Analysis will be proportioned in accordance with the design base shear, 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.
