Calculating Wind Loads
Wind loads are typically calculated using the following formula:Wind Load (psf) = Kz x V^2 / (1.86 x (ln(z/n)) + 5.2)Where:
- Kz = zone factor (a value between 0.002 and 1.0)
- V = wind velocity (mph)
- z = height above ground (ft)
- n = terrain roughness
For example, let’s consider a carport with a height of 20 feet and located in a city with a wind velocity of 50 mph. Using the formula above, we can calculate the wind load as follows:Wind Load (psf) = 0.002 x (50)^2 / (1.86 x (ln(20/2)) + 5.2) = 6.34 psf
Calculating Snow Loads
Snow loads are typically calculated using the following formula:Snow Load (psf) = 0.25 x h x (1 + 0.5xh^2)Where:
- h = roof height (ft)
- h = roof slope (in/ft)
For example, let’s consider a carport with a roof height of 12 feet and roof slope of 4 inches per foot. Using the formula above, we can calculate the snow load as follows:Snow Load (psf) = 0.25 x 12 x (1 + 0.5x(12)^2) = 22.5 psf
