What is the primary focus of ASCE 7 regarding wind?

• A. Understanding wind direction only
• B. Only structural steel requirements
• C. Electrical systems
• D. Understanding wind pressure vs wind uplift and the effects on roof zones

Answer: (D)

ASCE 7’s wind provisions focus on how wind creates pressures on surfaces and how those pressures translate into uplift, with special attention to how these forces vary across different roof zones. In practice, wind loads aren’t uniform: edges, corners, and other roof zones experience different pressure coefficients than the interior, leading to higher uplift near boundaries and lower uplift toward the center. The standard provides methods to estimate those pressures (including how factors like wind speed, exposure, height, and terrain affect them) and then apply them to the roof system, fasteners, and edge details so the structure can resist the resulting uplift. It’s not about wind direction alone, or solely about structural steel or electrical systems; it’s about understanding wind pressure, uplift, and how they manifest across roof zones.
