The most direct load on a building caused by wind is known as what?

• A. Lateral wind
• B. Direct wind
• C. Direct wind pressure
• D. Uplift

Answer: (B)

Direct wind describes the immediate pressure exerted by wind as it strikes a surface head-on. This is the most direct load because it acts perpendicular to the surface, pushing on walls and the roof as the wind hits them. Uplift is the vertical suction on the roof, and lateral wind refers to horizontal forces on the sides; both are important but represent components of wind loading rather than the direct, surface-normal pressure produced by the wind’s impact. So the primary, direct action of wind on the building is the direct wind loading.
