CALCULATOR NOTES

1. This calculator is for estimating purposes only and 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’ after fields are filled out to order a review & certification delivered to you for permit.

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 for mobile on the input labels to reveal more information about that item.

  INPUT AREA 1
             
The peak 3‐second gust wind speed. Consult your building department or engineer for governing codes. ASCE CODE YEAR
 
             
The peak 3‐second gust wind speed. Consult your building department or engineer for governing codes.       WIND VELOCITY, Vult
  MPH
             
See help for explanations. If unsure, use C for non coastal, D if near coastal or large flat terrains.      ASCE EXPOSURE CATEGORY
 
             
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
 
             
Use 1.0 for flat terrain. For areas on or near hills, this will need to be calculated elsewhere. Refer to the help for more. 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 End zone 5 is 10% of this value, 40% of height, but 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, a reduction is permitted for positive pressures based on the actual elevation. Enter the elevation from ground to the opening. ELEVATION OF INSTALLATION
  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°.

 ROOF SLOPE
 
             
# OF OPENINGS TO ANALYZE  
If yes, the calculaon for area of opening switches from Width * Height to Height * Height/3. It operates on the assumpon that impact shuers are tested infinite width. IMPACT SHUTTER ANALYSIS 
 
             
INPUT AREA 2
Positive is the force inward into the building, negative is pushing out. Expect larger negative values due to building pressurization. RESULTS
CORNER DIST 'a'
This is your label to help identify the answer on accompanying layout drawings. MARK
(W*L)/144 must be lower than 700ft² to use the C&C method. WIDTH-in
(W*L)/144 must be lower than 700ft² to use the C&C method. HEIGHT-in
 
Use Zone 4 for interior (non corner) openings. Zone 5 are any corners per sketch below & help. IF UNSURE USE 5! ZONE
