### Intent 1:

To limit the probability that the calculation of
wind effects on the building structure will not take into account
how the properties of the building structure affect dynamic amplification,
which could lead to structural failure, which could lead to harm to
persons.

### Intent 2:

To limit the probability of the implementation of
unacceptable design methodologies for the calculation of dynamic amplification
due to wind, which could lead to structural failure, which could lead
to harm to persons.

### Intent 3:

To exempt certain buildings from the application
of Sentence 4.1.7.2.(1), which would otherwise classify buildings
as not dynamically sensitive, if certain conditions are met.

### Intent 4:

To clarify how to calculate the effective width
of a building.
