Intent 1:
To limit the probability that the calculation of
wind load on a building will not take into account the expected maximum
winds at the site based on terrain roughness, the height of the surface
or part thereof above ground, and hill configuration, which could
lead to:
- the excessive deformation of, or excessive stress in,
structural elements, which could lead to damage to the building, or
- the excessive deflection or excessive vibration of structural
elements, which could impede the intended use and occupancy of the
building.
Intent 2:
To limit the probability that the calculation of
wind load used for the design will not take into account the height
of the surface or part thereof and shielding provided by surrounding
buildings or trees, which could lead to:
- the excessive deformation of, or excessive stress in,
structural elements, which could lead to damage to the building, or
- the excessive deflection or excessive vibration of structural
elements, which could impede the intended use and occupancy of the
building.
