ASCE 7-22 WALLS C&C wind pressure calculation
STATUS
Stable
STANDARD
asce 7 22
DESCRIPTION
This calculator determines design wind pressures for wall components and cladding (Zones 4 & 5) based on ASCE 7-22, Chapter 30, Part 1 (h ≤ 60 ft). It is intended for informational purposes only. Results must be verified by a qualified professional engineer.
ASCE 7-22 C&C Wall Pressure Calculator
Wall components and cladding, Figure 30.3-1: mean roof height h ≤ 60 ft. Enter the project-specific ultimate wind speed and assign each component to its wall zone. This calculator does not select the wind speed from the address or risk category.
Project & General Parameters
Determines internal pressure (GCpi).
Wind & Building Parameters
Ultimate design wind speed selected for the location and risk category. Do not enter an ASD-converted speed. The ASD factor is applied once to pressure.
Enter h per ASCE 7-22: use eave height for roof slopes ≤ 10°; otherwise use the applicable mean roof height.
Enter the actual slope. The 7° and 10° limits affect different rules; select the applicable figure for nonuniform roof geometry.
Low Slope applies 10% GCp reduction.
Preview: Ke = exp(−0.0000362 × elevation in ft), ASCE 7-22 §26.9. The Worker computes the authoritative value. Elevation input range: −2,000 to 15,000 ft.
Determine per §26.8; 1.0 applies when topographic speed-up is not required. This calculator accepts 1–4 as its supported input range.
0.85 for C&C on buildings (Table 26.6-1).
Component Information
An empty effective-area input assumes the entire window or door assembly is the element under consideration and uses its gross width × height. For individual framing members, mullions, panels or fasteners, supply the effective wind area determined for that element under ASCE 7-22 §26.2. The effective area may differ from gross area; selecting a zone requires the component’s location in plan.
