ASCE-7-16 & 7-10 Wall Components & Cladding Wall Wind Pressure Calculator

Use this tool to calculate wall zones 4 & 5 positive & negative ASD design wind pressures for your project.

CALCULATOR NOTES

1. This calculator is for estimating purposes only & NOT for permit or construction. Results are ONLY valid when signed & sealed from a professional engineer from Engineering Express.  Press ‘Order Certified Copies For Permit’ which appears after all fields are filled out to order a review of your submission & PE certification once approved delivered to you for permit submission.

2. Do not use fractions. Round up everything but width and height – round those down.

3. For Florida permits after January 1, 2021 & for 2018 IBC code, use the ‘ASCE -16-7th Edition Florida Building Code (2020) option.

4. Pressure results are Allowable Stress (ASD) design method.

5. Visit EngineeringExpress.com/Wind to learn more about the terms & parameters of this tool & HOVER over / press on the input labels for more information about that item.

6. Discounts available for frequent users by purchasing Tokens

This is generally 0.85. Change to 1.0 only if required by building department or special use case directed by the architect / engineer. WIND DIRECTIONALITY FACTOR Kd
 
Wind pressures are calculated for flat terrain by default. Local hills or ridges may increase calculated wind pressures. LOCAL TOPOGRAPHY
 
Use 1.0 for flat terrain. For areas on or near hills, ridges, or escarpments, this factor helps account for wind speeding up as it flows over the land. If required, this factor can be calculated separately by Engineering Express or the design engineer. Refer to the help glossary above for more information. TOPOGRAPHY FACTOR Kzt
 
For every 1,000 above sea level, atmospheric pressure and corresponding wind pressure is decreased per ASCE 7‐16. Select 0 if unsure or at sea level. ELEVATION ABOVE SEA LEVEL
FT
See help and image below. This is the shortest building dimension. The width of End zone 5 is 10% of this value, 40% of height, or not less than 3’ MIN OVERALL BLDG DIMENSION
FT
This is the average roof height from the peak to the eave. See image below. Your minimum heights will be adjusted to these values:
Exposure B => 30'
Exposure C => 15'
Exposure D => 7' MEAN ROOF HEIGHT, MRH
FT
For buildings over 60 FT, a reduction is permitted for positive pressures based on the actual elevation. Enter the elevation from ground to the lowest opening being analyzed. LOWEST INSTALLATION ELEVATION
FT
If the roof slope is less than 10 degrees, there is a slight reduction in pressure. If complex roof or unsure, set to >= 10°.

Positive values represent pressures directed at or against the building. Negative values are pressures pushing outward from inside the building, or creating suction on exterior faces. Expect larger negative values due to building pressurization. CALCULATED PRESSURES
