What does the exposure classification of a building imply with respect to wind?
What will be an ideal response?
The exposure classification refers to the roughness of ground around the building and is classified as Exposure B, Exposure C, or Exposure D. A densely built-area or highly forested area (greatest ground roughness) is Exposure B, a sparsely built area (lower ground roughness) is Exposure C, and an ocean front (lowest ground roughness) is
Exposure D. Everything else being the same, the greater the ground roughness, the lower the wind pressures.
