4.1.7.1.(3) | Application | Intent |
OS2 | OP2 | OH4 |
Objective | OH4 Vibration and Deflection Limitation |
Attribution | |
Application | Application 1: Method for calculating the net specified pressure
due to wind on part or all of a surface of a building using
the specified external wind pressures or suctions determined in Sentence 4.1.7.1.(1) and
the specified internal pressures or suctions due to wind on interior surfaces
of buildings calculated using the formula provided.

Intent | Intent 1: To limit the probability that the calculation of net wind
pressure on a building surface will not take into account how external and
internal pressures or suctions on building surfaces act to produce forces
in structural elements, which could lead to the excessive vibration or excessive
deflection of structural elements, which could lead to negative effects on
the psychological well-being of persons. Intent 2: To limit the probability that the calculation of specified
wind pressures or suctions on interior surfaces of buildings will not take
into account all the factors that affect the expected maximum magnitude and
distribution of wind pressures or suctions on interior surfaces of buildings,
which could lead to the excessive vibration and excessive deflection of structural
elements, which could lead to negative effects on the psychological well-being
of persons. Intent 3: To limit the probability that the calculation of wind load
used for the design of the building structure for vibration will not take
into account the level of reliability appropriate for vibration serviceability,
which could lead to the excessive vibration of the building, which could lead
to negative effects on the psychological well-being of persons.
