ASCE 7-22 Minimum Design Loads for Florida Structures
The Florida Building Code (FBC 8th Edition, 2023/2026 update) mandates that all aperture design pressures must be calculated in strict accordance with ASCE 7-22 Chapter 26–30.
The Velocity Pressure Equation ($q_z$)
Our in-house engineering team calculates localized wind pressure using the fundamental velocity pressure formula:
Where:
• $V$ = Ultimate Design Wind Speed (155 to 185 MPH)
• $K_z$ = Velocity Pressure Exposure Coefficient (Height & Exposure)
• $K_{zt}$ = Topographic Factor (Canal embankments & coastal bluffs)
• $K_d$ = Wind Directionality Factor (0.85 for Buildings)
• $K_e$ = Ground Elevation Factor
Exposure Category Breakdown
• Exposure B: Urban and suburban areas with closely spaced obstructions (Inland Kendall, Plantation).
• Exposure C: Open terrain with scattered obstructions (Open agricultural land, large suburban golf courses).
• Exposure D: Flat, unobstructed coastal strips facing water bodies extending 1 mile or more (Palm Beach Island, Miami Beach, Star Island, Key Biscayne).
