4.1.5.12.(4)ATTRIBUTION:
Functional Statement:
F20
To support and withstand expected loads and forces.
Objective:
OS2.1
APPLICATION:
Minimum specified horizontal force parallel to the
top of the rails to be used for the design of crane runway structures.
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 dynamic structural effect
of horizontal dynamic forces parallel to the rails due to the operation of
cranes will not be taken into account in the design of crane runway structures,
which could lead to structural failure, which could lead to harm to persons.

OP2.1, OP2.4
APPLICATION:
Minimum specified horizontal force parallel to the
top of the rails to be used for the design of crane runway structures.
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 4.
INTENT:
To limit the probability that the dynamic structural effect
of horizontal dynamic forces parallel to the rails due to the operation of
cranes will not be taken into account in the design of crane runway structures,
which could lead to the excessive deformation of, or excessive stress in,
structural elements, which could lead to damage to the building.
