Classify the building based on its use (Category I to IV). This determines the Importance Factor (
Open terrain with scattered obstructions (the default). Exposure D: Flat, unobstructed areas and water surfaces. Step 4: Calculate Velocity Pressure ( wind load calculation as per asce 7-05
q = 0.00256 * Kzt * Kz * G * Cp * V^2
From Fig 6-11A, low-rise? h=35 ≤60, yes: ( GC_p = -0.85, +0.70 ) for zone 4 ( p_suction = 31.33(-0.85) - 31.33(0.18) = -26.63 - 5.64 = -32.27 ) psf ( p_pressure = 31.33(0.70) - 5.64 = 21.93 - 5.64 = +16.29 ) psf Classify the building based on its use (Category I to IV)
