Solution
The windward side of a building generally encounters positive pressure due to direct wind impact, resulting in an outward force against this structural facade. Positive pressure refers to the force exerted by the wind on a structure in the direction perpendicular to its surface, creating an outward push. This force occurs when the wind strikes the surface directly, generating an increase in pressure. Conversely, negative pressure, also known as suction or suction pressure, occurs when the wind creates a low-pressure zone on the leeward side of the structure, causing a pulling force inward. Negative pressure happens as wind flows around the structure, creating a suction effect due to the pressure drop behind it.
Consequently, side A represents the windward side experiencing wind pressure, while side B, the leeward side, is subjected to negative pressure conditions. This distinction creates a differential pressure environment wherein side A undergoes a positive pressure state while side B experiences a negative pressure state, illustrating the dynamic interplay between wind forces and structural responses in architectural contexts.
